Tamron 17-70 F2.8 Di III-A VC RXD field review
Introduction
The Tamron 17-70 F2.8 Di III-A VC RXD is a very compact general-purpose lens for Sony’s APS-C, E-mount mirrorless cameras. Think of it as roughly equivalent to a 24-105mm F4 lens on a full-frame camera, but scaled down to match the APS-C sensor format.
Although it’s designed for cameras with APS-C sensors, it can still be used with full-frame models when cropped to APS-C. We tried both approaches for this review, pairing it with the Sony a6600 as well as the Sony a7R IV in APS-C crop mode.
With a constant F2.8 maximum aperture across its zoom range, the Tamron 17-70mm makes a great travel lens for photographers on a budget. It also shows potential as a video lens thanks to its vibration control and lack of focus breathing. It’s available now at a price of $799.99 USD.

Tamron launched the 17-70mm F2.8 Di III-A VC RXD in late 2020. It’s both the company’s first F2.8 zoom for sub-frame mirrorless cameras, and the industry’s first to achieve a 4.1x zoom ratio, so we were keen to try it in the real world.
For our review, DPReview TV host Chris Niccolls took it on a road trip to the Calgary Zoo and the nearby town of Okotoks, Alberta, while editor Dan Bracaglia gave it a whirl closer to home around DPReview’s headquarters in Seattle.
Let’s take a look at what the Tamron 17-70m F2.8 can do and what it’s like to use.
All sample images edited in Adobe Camera Raw 13 with adjustments limited to white balance, exposure, highlights, shadows, white and black levels. Sharpening and noise reduction at ACR defaults.
Handling
The 17-70mm F2.8 is pretty typical of Tamron’s modern product line. At 524g (18.5oz), it’s very lightweight, but build quality is nevertheless pretty good.
A pair of rings encircle the lens barrel, with the smaller of these near its tapered base controlling manual focus, and the larger one adjusting the focal length. Up front there’s a 67mm filter thread, a size that’s also common on many of the company’s other lenses.
Absent from the lens, though, are any buttons. We found that to be a somewhat perplexing omission; with no dedicated controls for focus mode or vibration control, owners of the Tamron 17-70mm F2.8 will have to spend more time in their camera’s menu system than would otherwise be the case.
The good news is that Tamron’s vibration compensation is generally really solid, and functions well in combination with in-body stabilization if supported by your camera body.
The zoom ring is very smooth and well-balanced. The manual focus ring has relatively little damping and so feels very light in use, but that’s pretty typical of lenses in this category. An internal focusing design means that focus adjustments won’t change the lens barrel’s length or cause filters to rotate, although turning the zoom ring will cause the barrel to extend or retract to match.
Autofocus and manual focus
The Tamron 17-70mm F2.8 foregoes the fancy linear motors typical of higher-end lenses, opting instead for a stepper motor-based autofocus drive. Yet despite that choice, AF performance is nevertheless very impressive, with even significant shifts in focusing distance taking just a fraction of a second on our Sony a7R IV body.
And while this is by no means a macro lens, it can still focus fairly close. At wide-angle, the minimum focusing distance is as little as 19cm (7.5″), yielding a maximum magnification of 0.21x (1:4.8). At telephoto, meanwhile, you can focus to around 39cm (15.4″) for a slightly lower magnification of 0.19x (1:5.2).

The good news, though, is that there is almost no focus breathing regardless of focal length. What that means is that the focal length doesn’t noticeably change when focus is adjusted. Along with its quiet autofocus drive, this makes the 17-70mm F2.8 an attractive option for videographers.
Image quality
The Tamron 17-70mm F2.8 pairs nicely with either Sony’s APS-C mirrorless bodies, or with its full-frame models when using the APS-C crop mode. Sony’s APS-C cameras currently top out at 24 Megapixel resolution, while the full-frame a7R IV can extract just a smidgen more detail from its 26.2 Megapixel APS-C crop. We used the latter for our image quality comparison.

Sharpness
Near its 17mm wide-angle, the lens is pretty sharp across the entire image frame when shooting wide-open at F2.8. In fact, we didn’t notice much difference in detail levels when stopping down to F5.6, even in the corners.
And the news is almost as good at the 70mm telephoto end, too. Again, sharpness was very good across the frame at F2.8. We did see some improvement to detail when we stopped down to F5.6 this time, even towards the center of the frame, but it was a relatively subtle difference.

Vignetting and distortion
The 17-70mm F2.8 exhibits quite strong distortion throughout its focal length range. At 17mm there’s significant barrel distortion, and as you zoom in, pincushion distortion is readily visible at mid- to tele-photo focal lengths. While distortion is easily fixed in post-processing, the large amount of it present in this lens means it’s likely to impact corner sharpness and, furthermore, will mean a slightly longer corrected minimum focal length on the wide end.
Vignetting is well-controlled throughout the zoom range, with some darkening of the corners which is easily corrected in post-processing.
Although there’s quite strong distortion at wide-angle, it can easily be corrected in post-processing. ISO 100 | 1/1000 sec | F2.8 | 26mm equiv. | Sony A6600 Photo by Dan Bracaglia |
Bokeh
There are a couple of weak spots in the Tamron 17-70mm F2.8’s image quality, and unfortunately bokeh is one of them. Amateurs and enthusiasts will likely find it more than acceptable, but users on a quest for maximal image quality may want to spend a bit more for a higher-performing alternative.
The problem, specifically, is quite strong onion ring bokeh. Out-of-focus highlights in images shot with the Tamron appear to be patterned by numerous concentric circles, giving their bokeh an undesirably busy appearance.
The 17-70mm F2.8 is quite prone to onion ring, giving its bokeh a rather busy look. ISO 1600 | 1/250 sec | F2.8 | 105mm equiv. | Sony a7R IV (in APS-C crop mode) Photo by Chris Niccolls |
Cat’s eye effect – which causes elliptical rather than round bokeh as you stray further from the center of the frame – is relatively mild, and mostly goes away once you stop down to F4. However, wide open the circle of confusion is increasingly truncated at image peripheries as in the image above. In other words, you may notice chopped-off out-of-focus highlights and generally busier – or sometimes swirly – bokeh as you stray away from the center of the frame.
Flare and sunstars
If you’re a fan of sunstars in your landscape images, the Tamron 17-70mm actually puts up a pretty good showing in this regard, with pretty 18 well-defined ‘spikes’ coming from small, bright light sources in the frame.
In this, an odd landscape photo of a dystopian future where we are ruled by cameras and smartphones (wait, we’re in that world already, aren’t we, and this is just a gear cabinet), you can see that at smaller apertures the Tamron 17-70mm F2.8 produces some pretty solid sunstars. ISO 12800 | 1/20 sec | F16 | Sony a6600 |
On the other hand, the Tamron 17-70mm is rather prone to flare, which could prove more of a concern. If bright light sources like the sun can be kept out of the frame, though—and the provided compact lens hood certainly helps here—then things aren’t too bad.
Cherry-red flare artifacts can prove problematic if you can’t keep the sun out of the frame. ISO 100 | 1/200 sec | F4 | 77mm equiv. | Sony a7R IV (in APS-C crop mode) Photo by Chris Niccolls |
If the sun is in your shot, though, the lens hood can’t help you, and you’ll see rather intrusive cherry-red ghosting, something that can be a pain to fix in post. Again, for Tamron’s target market it’s not likely to be a big issue, but it may push more advanced users up the line to a more-expensive rival.
Lateral and longitudinal chromatic aberration (fringing)
Lateral CA is a type of fringing around high-contrast edges near the edges of the frame; it’s called ‘lateral’ because it appears to the left or right (or top or bottom, depending on the orientation) of these edges. While it’s not attractive, it’s usually easy to remove, and not a particular concern for the Tamron 17-70mm F2.8, largely because with this lens it’s automatically corrected for in JPEGs and in Raw converters.
Longitudinal CA or LoCA can be seen as cyan / magenta fringing in the bokeh circles of this shot. ISO 100 | 1/1000 sec | F2.8 | 105mm equiv. | Sony a7R IV (in APS-C crop mode) Photo by Chris Niccolls |
Longitudinal CA, which appears as cyan / magenta fringing just in front of and behind the plane of focus in the Tamron, can be far more troublesome and difficult to remove. It’s not terrible, by any means, but it’s definitely there, and something to be aware of. Note the cyan fringing around highlights around the lettering behind the plane of focus.
Conclusion

Despite a few minor issues that may cause users chasing ultimate image quality to look elsewhere, we think the Tamron 17-70 F2.8 Di III-A VC RXD shines at its $799.99 USD price point. That’s great news, because there really aren’t a lot of alternatives.

If the sometimes-busy bokeh, strong distortion and flare aren’t big concerns for you, and you can live with the slight inconvenience of its lack of physical controls, there’s a lot to recommend this lens. We found ourselves especially surprised both by its corner-to-corner sharpness across the focal range, even when shooting at or near wide-open. And autofocus performance is very impressive, too.
Yet it’s a good 20% cheaper than its nearest rival, Sony’s Zeiss Vario-Tessar T* E 16-70 mm F4 ZA OSS ($999.99), which does not offer unequivocally better image quality. And it’s in a totally different league to the only more-affordable option, the Sony E PZ 16–50 mm F3.5–5.6 OSS ($299.99), a lens which we honestly can’t recommend for anything other than the portability offered by its small size.
And of course, neither of those lenses can match the Tamron’s continuous F2.8 maximum aperture. For that, you’d need to look to the much-pricier Sony E 16–55mm F2.8 G lens. That optic, while excellent, is priced at $1,299.99, and is nearly two-thirds more expensive than the Tamron 17-70mm F2.8, despite offering a narrower zoom range (though some will prefer its wider starting focal length).
Despite some optical flaws, the combination of edge-to-edge sharpness, versatile range, bright aperture and great value is currently hard to find in the APS-C E-mount lineup. If you’re in the market for a new travel zoom for your Sony APS-C camera, the Tamron 17-70mm F2.8 Di III-A VC RXD unquestionably deserves a spot near the top of your shopping list, and easily garners a Silver Award from us here at DPReview.

The APS-C lens landscape has changed
Images: Canon, Nikon |
It wasn’t long ago that many of our reviews of APS-C cameras had to come with a warning: no matter how good the body was, you were almost certainly going to be limited by lens selection. This was especially true with Nikon and Canon’s mirrorless cameras. Sony has followed its longstanding tradition of letting third parties build out a healthy selection of lenses, and the selection for Fujifilm’s APS-C-only X-mount is second to none, but Nikon’s Z mount and Canon’s RF mount appeared to be almost completely locked down. As a result, you could count the number of APS-C lens options available on your fingers.
But things are changing. Over the past year, we’ve seen several APS-C lenses announced and released for Canon and Nikon cameras, filling notable gaps in the first-party lens lineups. But while the situation is improving, it’s clear that the two companies are still in control.
This week, Sigma released four APS-C primes for Canon’s RF mount, making good on its promise to release six licensed lenses for the system – earlier this year, it released the 10-18mm F2.8 and 18-50mm F2.8. Meanwhile, Nikon has allowed Sigma to release select primes for Z-mount – a trio of F1.4 primes at 16, 30, and 56mm. It’s worth noting the company’s 23mm F1.4 is the only one of its APS-C primes that it hasn’t brought to Z-mount; it likely isn’t a coincidence that Nikon’s only first-party APS-C prime lens is a 24mm F1.7.
Sigma’s APS-C prime lens lineup is quite good, and now most of them are available for almost any mirrorless APS-C camera.
Image: Sigma |
However, Nikon hasn’t stopped companies like Viltrox and Sirui from releasing a slew of Z-mount APS-C prime lenses, complete with autofocus. If you pick up a Nikon Zfc or Z50II, you can get anywhere from a 13mm F1.4 (20mm equiv.) to a 75mm F1.2 (113mm equiv.) to go with it, as well as most of the classic focal lengths in between.
Your choices are no longer limited to a few first-party options, manual-focus only lenses, or glass meant for full-frame bodies
This is an important change for APS-C shooters. Even going back to the DSLR days, it’s felt like many manufacturers have viewed the format as a stepping stone to full-frame rather than something enthusiasts and pros might consciously choose. Neither Canon nor Nikon have been particularly prolific when releasing new APS-C glass. But with the gates being slightly opened, you’re no longer limited to a few first-party options, manual-focus-only lenses from third parties, or heavier, more expensive full-frame lenses. Now, there’s at least some selection of third-party lenses with autofocus to choose from, alongside Canon and Nikon’s offerings.
This isn’t to say that you can now buy any APS-C camera you want and be assured that all the lenses you want will be available – you are still at the mercy of what Canon and Nikon wish to allow. While plenty of primes are available for Z-mount APS-C cameras, no fast zoom lenses are available; Nikon’s all start at F3.5 and end at F5.6 or F6.3.
In fact, there are currently no third-party APS-C zooms available for Nikon Z-mount at all, despite the fact that two have made the jump from E and X-mount to RF – it also goes without saying that there are many others more available on Fujifilm and Sony’s systems. That’s a bummer for anyone looking to step up from the kit lens or wanting to shoot sports or birds in anything but ideal lighting without having to shell out for and lug around a full-frame 70-200mm.
Tamron has promised to bring its 11-20mm F2.8 APS-C lens to Canon RF mount this year as well – no word on Z-mount, despite Tamron bringing some of its full-frame lenses to Nikon.
Image: Tamron |
RF mount at least has the two constant F2.8 zooms thanks to Sigma, with one more on the way from Tamron, though those are all at the wide end. However, there are far fewer autofocus primes available for Canon, as manufacturers like Sirui and Viltrox aren’t producing them. That’s not surprising; a representative for the latter once said that Canon had told it to stop producing products for RF mount. The 85mm F1.4 lens that Samyang announced for the system in 2020 also disappeared from the market not long after.
In a perfect world, these problems wouldn’t exist. Canon and Nikon would make the lenses that their APS-C cameras needed to stand on their own feet as a real alternative to full-frame options, and there would be robust competition from third parties, which would be allowed to make whatever lenses they want.
None of that seems particularly likely. However, at least those who choose to shoot with a smaller sensor in a Canon or Nikon body have gotten a wider choice of lenses, even if they’re still bound by the companies’ rules.
At the end of the day, that’s better for everyone interested in APS-C, because it means that cameras like the EOS R7 and Z50II are competitive with the Sony a6700 and Fujifilm X-T5 in a way that they wouldn’t have been with an extremely limited lens selection. With any luck, this trend will continue, and the APS-C landscape will become more competitive – even if Canon and Nikon aren’t giving it their full attention.

Sony a1 II initial review: is Sony's flagship camera another game changer?
The Sony Alpha 1 II is the company’s latest flagship full-frame mirrorless camera. It’s built around the same 50.1MP stacked CMOS sensor as the original but now includes an “AI processing unit,” which allows its autofocus system to recognize seven different subject types and to automatically select one based on what’s in the scene.
Key specifications
- 50.1MP stacked CMOS sensor
- In-body stabilization rated at up to 8.5EV
- Improved autofocus subject recognition with automatic selection
- Continuous shooting at up to 30fps with full AF tracking
- Pre-release capture from 0.03 to 1 second
- Fully-articulated rear screen on tilt-out cradle
- 8K 30p video downsampled from 8.6K / 4K 120fps
- 9.44M dot 240fps viewfinder – full res up to 120fps
The a1 II will retail for $6,499.99 – the same as its predecessor – and will be available in mid-December.

What’s new
Despite using the same sensor as its predecessor, Sony claims the a1 II will have improved image quality at mid-to-high ISOs thanks to its improved image processing engine. Presumably, these improvements will only appear in the JPEGs.
Improved Autofocus
The original a1’s autofocus system could recognize humans when shooting stills and videos, and animals and birds when shooting stills. The a1 II, however, inherits the dedicated “AI processor” seen in cameras like the a7R V and a9 III and can now recognize even more subjects: it adds insects, cars, trains and airplanes. All the recognition modes are now available in movie mode as well, and the system can specifically target key parts of recognized subjects, such as a driver’s helmet.
The a1 II brings an ‘Auto’ subject recognition mode to the Alpha line
Sony also claims that human and animal eye recognition should be around 30% better than the a1 and that bird eye recognition should be 50% better. The Animal and Bird modes have also been merged, meaning you won’t have to switch between subject recognition modes if you want to go from shooting animals to birds or vice versa.
The a1 II’s Auto Subject Detection mode lets you narrow-down the types of subject it’ll search for, to help optimize the performance. |
Not that you would necessarily have to switch modes manually. The a1 II is Sony’s first Alpha camera to have an Auto subject recognition mode, where it can determine what type of subject it should be tracking and lock on to it. As with the similar system on Nikon’s cameras, this comes with a small speed penalty compared to having a specific subject recognition mode selected. However, it can be useful if you need to quickly go between shooting a variety of subject types.
You can also speed up the system by limiting which types of subjects the Auto mode selects between; for example, you can make it so it only looks for humans, animals, and birds if you’re not planning to shoot any insects or vehicles.
Finally, Sony’s also adding extra small and extra large spot focus area options.
Pre-Capture
One feature that’s become commonplace since the launch of the a1 is pre-capture – a way for the camera to save the moments before you press the shutter, helping you capture key moments beyond your ability to anticipate them. The a1 II adds it, recording up to 30 frames in the moments leading up to you pressing the shutter button, though if you want to go above 20fps, you will be limited to using lossy compressed Raws instead of lossless compressed ones. When enabled, the pre-capture is activated by a half-press of the shutter, the press of the AF button, or both, depending on your settings.
You can set the pre-record window to be as short as 0.03 seconds or as long as a second, with several options in between.
Better stabilization
The a1 II’s internal image stabilization is now rated for up to 8.5 stops in the center of the frame and 7 stops on the periphery (a new CIPA metric), up from a 5.5 stop rating on the a1.
Viewfinder tweaks
Hardware-wise, the a1 II’s EVF seems largely unchanged from the a1’s: it’s the same resolution and can run at the same 240fps. However, Sony says you can now run in 120fps mode with display quality set to ‘high,’ though you will still see a drop in resolution if you go up to 240fps.
There’s also now a ‘deep’ viewfinder eyecup included in the box, alongside the standard one
Video
The a1 II retains most of the original’s video specs. This means 8K capture at up to 30p, full-width 4K capture at up to 60p and up to 120p with a 1.13x crop. The 4K isn’t derived from the 8K footage, though, so you don’t gain the detail benefit of 2x oversampling.
The a1 II adds a few quality-of-life updates, though. The most impactful will probably be the aforementioned support for using all the subject tracking modes while shooting video, but you can also now import up to 16 custom LUTs that you can use to preview what your Log footage will look like when graded. You can also embed the LUT alongside your files, so that someone else editing your footage can match your intended look.
Just as we’ve seen with Sony’s other recent large-sensor cameras, the a1 II only shoots the S-Log3 profile, which captures a very wide dynamic range. It no longer offers the less expansive S-Log2 option. The a1 II also gains the attractive and flexible S-Cinetone profile if you don’t want to color grade in post.
The camera also has the Auto Framing feature found on some of Sony’s vlogging cameras, where it will crop in on the subject and move the frame around to make it seem like there’s a cameraperson tracking them. There’s also a ‘Dynamic active’ image stabilization mode, which Sony says will increase the stabilization by up to 20% compared to the standard ‘Active’ mode, and a ‘Framing Stabilizer’ mode that’s meant to ensure that your frame maintains the same composition as much as possible when shooting handheld.
Noise Reduction Composite Raw
Sony has expanded on the a1’s pixel shift multi-shot mode, adding a noise reduction mode that shoots between 4 and 32 Raw images that can be composited together using a desktop computer running the company’s Imaging Edge software. Sony pitches it as a mode for low-light portraiture.
It’s most easily understood as a multi-shot mode without the pixel-shift movement. Rather than trying to boost resolution it aligns and combines multiple images to boost the signal-to-noise ratio (ie: tonal quality) at each pixel position. As with pixel shift mode, it’ll work best when there’s little to no movement within your scene.
The a1 II also gains focus bracketing, which the original a1 lacked.
How it compares
The most direct competitor to the a1 II is Nikon’s Z9, its pro-focused high speed, high resolution model. Canon’s EOS R1 lower resolution makes it more of an a9 III competitor, but it’s these models primarily and explicitly made for professional shooting in the most demanding circumstances that Sony’s trying to target.
However, given how much of the Z9 and R1 Nikon and Canon have included in the Z8 and EOS R5 II, respectively, it’s also fair to include one of those models here, too. Sony doesn’t use the two-grip and larger battery design for its pro models, which makes the comparison even more inviting, despite them being a different class of camera.

* – Sony rates its AF sensitivity using an F2 lens, while Nikon and Canon use an F1.2 lens. We’ve adjusted Sony’s rating by -1.33EV to account for the difference.
The a1 II has the joint fastest shooting rate here and its sensor readout is quicker than the roughly 1/160 that the EOS R5 II can achieve. Likewise it has a built-in Ethernet connection, which the Canon lacks and, unlike the EOS R5 II and Nikon Z8, has matched card slots so that pros can focus on a single type of media and never have to worry about an performance difference between slots.
It’s much more evenly-matched against the Z9, which has a much lower resolution viewfinder but a low-latency readout path from its sensor to make the viewfinder more responsive. The Z9 can only shoot at up to 20fps in Raw, dropping to 12-bit readout and JPEG-only mode to hit 30fps.
Body and handling
Given that the a1’s audience is professionals who use it day in and day out, it’s no surprise that Sony has been conservative with changes to its magnesium body and controls – the a1 II’s tweaks are largely the same as the a9 III’s, with the grip getting deeper and the shutter button being angled forward towards your finger.
The dials and buttons are largely in the same places, though the exposure compensation markings have been removed from the locking top-plate control dial. The stills / video / S&Q modes have also been moved to a sub-dial rather than being settings on the mode selector dial, and the drive select dial now has a disable setting that lets you control the camera’s drive mode purely through menus.
The a1 II also features an additional programmable button on the front next to the grip. By default, it acts as a ‘Speed Boost’ button, upping your shooting rate as you hold it down. For example, you could be shooting at 15fps and press the button to start shooting at 30fps for a few seconds when the action speeds up or when you want to be sure you’ll capture a specific moment. This option can be moved to another button and the boosted frame-rate can be tailored to suit your subject.
The biggest physical change is the display. It’s a bit larger and higher resolution than the a1’s, and it can now tilt in addition to being fully articulated. It’s a design we saw with the a7RV, and one that should make both photographers and videographers happy. It also has the slightly updated menu system from the a7RV as well, with the interactive settings tab.
As discussed above, the viewfinder is largely still the same, with a large 0.9x magnification and 9.44M dots giving a resolution of 2048 x 1536px. Its 120fps mode is nicer to use now that it doesn’t come with a substantial drop in resolution.
Ports and slots
The a1 II’s I/O is largely unchanged from its predecessor, though the ports have moved around a bit. It still has a headphone and microphone jack, a USB-C port that runs at 3.2 Gen 2 10Gbps speeds, a full-size HDMI port, Sony’s micro USB ‘Multi’ accessory port, and a flash sync port.
It also has dual-band 2.4 and 5GHz Wi-Fi with 2×2 MIMO and an upgraded Ethernet port that runs at 2.5Gbps instead of the 1Gbps speeds the port on the a1 was limited to. That should make transferring large videos and batches of photos over long distances faster – try finding a high-speed USB-C cable that’s more than a few meters long – and is another sign of the pro workflows this camera is designed to support. The Ethernet port also now has a Wake on LAN feture that can be used to remotely turn the a1 II on using Remote Camera Tool.
On the other side, the a1 II features a pair of the combined CFexpress Type A / UHS-II SD card slots for storage that feature on many of Sony’s cameras.
Battery
The a1 II uses Sony’s NP-FZ100 batteries, and includes a dual-battery charger in the box, which it claims will charge two batteries at once in around 155 minutes.
The camera is rated to give 420 shots per charge when using the rear screen. As always, CIPA figures tend to significantly underestimate the actual number of shots most people will get, and this discrepancy gets significantly larger when you’re shooting bursts. But, while we’d expect a camera rated at 420 shots per charge to actually be able to shoot multiple times this number in practice, it’s usually a good indicator of how its battery life compares with other cameras (ie: if it gets a rating 50% lower than another camera, it’s likely to capture around 50% fewer shots per charge).
Initial impressions
By Richard Butler
The a1 II’s AF proved very effective at staying focused on the player we’d specified, in our testing so far.
Sony FE 400mm F2.8 GM OSS | F2.8 | 1/4000 sec | ISO 640 |
When the original a1 arrived, just shy of four years ago, it represented an unprecedented combination of high resolution and speed. Despite a 50MP sensor, its Stacked CMOS design with on-board RAM let it capture stills at up to 30fps with readout speeds of around 4ms (fast enough to allow flash sync at up to 1/200 sec). This was around four times faster readout than the 20fps Canon EOS R5, which had previously come closest to offering high-speed and high res.
However, in the time that’s passed, both Canon and Nikon have produced fast high-res bodies and done so at something closer to a consumer-reachable price, leaving Sony’s pro flagship looking expensive, rather than exemplary. Don’t let this or Sony’s single-grip approach fool you: the a1 II is designed to square-up against the Z9 and R1, not the Z8 and R5 II. But it goes to show how quickly things have been moving that these more affordable models can match so much of the of the original a1’s spec and offer more advanced subject recognition.
The a1 II helps redress this balance, somewhat, pairing the same processing capabilities as Sony’s other pro-focussed model, the a9 III, with the 50MP Stacked CMOS sensor. This includes the gain of subject recognition AF modes with the first ‘Auto’ option that lets you pare back the range of subjects it hunts for, to hit an optimal speed/convenience balance for your photography. We’ve been very impressed by the camera’s AF performance so far.
The a1 II also gains the pre-capture option that’s been becoming increasingly common on action-focused cameras. It still tops-out at 8K/30 on the video side though, and has no option for 4K derived from this 8K capture, leaving it behind both the R5 II and Z8 in this regard.
Interestingly, the a1 II still needs to drop to Sony’s damagingly lossy Raw format at 30 fps: it can only shoot lossless compressed Raw at 20fps. The difference only becomes apparent at high-contrast edges after significant editing pushes, so is unlikely to be a major issue for action shooting, but it’s a surprise that this couldn’t be addressed with the Mark II’s greater processing grunt.
“It’s these workflow features aimed at professionals that try to set the camera apart”
Critically, the a1 II also includes a series of features from both the a1 and the a9 III designed specifically for professionals trying to deliver images quickly that the less expensive rivals lack. This includes a variety of transfer options, including SFTP and several ways of marking files to be transferred. We’d also expect the a1 II to gain the ability to encode C2PA authentication metadata to its files.
Unsurprisingly, it’s the cumulative impact of these workflow features aimed at professionals working in high-intensity environments that try to set the camera apart. And if you’re not one of those people (and most of us aren’t), then the a1 II almost certainly isn’t worth so much more than the more consumer-priced models.
But how can these small details, an Ethernet port, that huge, high-res viewfinder and details like matched media card slots really add up to justify a 50% premium over the enthusiast/pro crossover bodies, such as the Z8 and EOS R5 II? Ultimately, it may simply be a ‘Pro Tax’: that $6K is how much a pro-focused camera costs. It’s the amount the market has shown it will bear, and it’s likely to be how much companies (including single-photographer companies) will have budgeted.
If there’s any doubt in your mind about whether the a1 II is worth the extra $2000 over the Z8 or EOS R5 II, then you’re not its target audience, and consequently it almost certainly isn’t, But if you are a Sony-shooting pro, the a1 II adds significantly to the skill-set of the previous model. But against dramatically improved competition and with so much Z9 and R1 tech trickling down to the Z8 and R5 II, it’s not the game-changer its predecessor was. We’ll get a chance to test this assessment as we continue using the camera.

Sony's new 28-70mm F2 GM is a zoom for dark places

Sony has announced the FE 28-70mm F2 GM, a zoom lens that trades 4mm at the wide end for an aperture that’s a stop brighter than the one found on a classic 24-70mm F2.8. It’s the company’s first constant F2 zoom lens for its E-mount cameras.
The lens’s optical formula consists of 20 elements in 14 groups, with three aspherical lenses, three super ED elements, and one ED element. It uses an 11-blade aperture. The front element has an oil and water-resistant flourine coating, and the lens is moisture and dust resistant.
It’s far from a compact lens, though it’s not as monstrously large as you might expect – it weighs in at 918g (32 oz) and is around 140mm (5.5″) long. It has an 86mm filter thread.
Sony makes it obvious what lens it’s competing with; highlighting that it’s 36% lighter and 11% smaller in diameter than Canon’s RF 28-70mm F2 L lens while claiming better corner-to-corner sharpness. The company also says the lens’s four linear motors can focus even when shooting at 120fps, and emphasized that they’re quieter than the older ring-type ultrasonic style motor in the Canon F2. In fairness, that lens was one of the original RF-mount releases, announced in 2018.
“Sony makes it obvious which lens it’s competing with”
The quieter operation should help when shooting video. Other pluses for video: it has an internal focusing mechanism which should make it easier to use the lens on a gimbal, the ability to switch the aperture ring into clickless mode and supports the focus breathing compensation mode included on some Sony bodies. You can also set the manual focus ring to have a linear response, which should make focus pulls easier.
The lens has a variety of switches and buttons. There are two customizable focus hold buttons, an Iris lock switch, the aperture click switch and a zoom smoothness switch that lets you adjust between “smooth” and “tight” torque settings.
It’s not the fastest zoom lens available for E-mount: at the time of writing, that prize goes to Sigma’s 28-45mm F1.8, though that model has substantially less reach on the tele end and only a 1/3EV increase in light-gathering ability.
The FE 28-70mm F2 GM will be available in mid-December and has an MSRP of $2,899.
Sony Electronics Announces Its First Constant F2 Aperture Zoom Lens: The Full-Frame 28-70mm F2 G Master™
The Unique Combination of a Versatile Focal Range, Large F2 Aperture, and Compact Form Factor
SAN DIEGO, Nov. 19, 2024 – Sony Electronics Inc. introduces the 28-70mm F2 G Master, the first1 Sony zoom lens with a constant F2 aperture and 77th lens in the Sony E-Mount lineup. This full-frame lens offers a versatile focal range from 28mm to 70mm while delivering prime-like2 bokeh with its constant F2 aperture. Despite its wide aperture and zoom range, the 28-70mm F2 G Master remains compact, lightweight, and well-balanced, making it ideal for both photography and video applications. This combination of zoom range, large aperture, and compact design makes this an innovative and versatile lens for portrait, sports, wedding, event, and video professionals.
“Our goal with the 28-70mm F2 G Master was to create a high-performing zoom lens that could be a strong single lens alternative to multiple primes,” said Yang Cheng, Vice President of Imaging Solutions, Sony Electronics Inc. “We prioritized a lightweight design during the engineering process as we knew that was a critical factor for real-life, practical use. And in a manner that only Sony can do, we were able to deliver a small, standard F2 zoom lens that does not sacrifice image quality. We’re proud to add this to our G Master series and believe it is one of the most innovative lenses ever offered to professionals.”
Sharp Imagery and Beautiful Bokeh
The 28-70mm F2 G Master produces extremely sharp corner-to-corner results throughout the entire zoom range, even while shooting wide open at F2. The high-resolution output is made possible by the three XA (extreme aspherical) elements and three aspherical elements built within the lens that minimize aberrations. The lens also features a floating focusing system that helps maintain internal stability. This focusing mechanism enables an impressive minimum focusing distance of up to 14.8 inches (0.38m) throughout the entire zoom range.
Staying true to the G Master lens lineage, the lens’ aperture up to F2 produces extraordinary bokeh, ideal for creating images that showcase a shallow depth of field. The 28-70mm F2 amplifies the G Master bokeh standards through a newly designed 11-blade circular aperture unit. Chromatic aberrations, which cause color fringing within photos, are effectively minimized with three Super ED (extra-low dispersion) elements and one ED element built within the lens. Additionally, Sony’s Nano AR Coating II reduces flare and internal reflections, ensuring clear images, even when strong light sources are present in the frame.
Compact, Lightweight Design Without Compromising Quality
The 28-70mm F2 G Master is one of the most advanced mirrorless camera lenses manufactured with a total 20 different lens elements arranged within 14 internal groups. Despite the advanced optical design, the lens remains compact at 3.6 x 5.5 inches (92.9 x 139.8mm) and lightweight at approximately 32.3 ounces (918g). The combination of imaging performance and a compact form factor offers an innovative solution that meets the demands of industry professionals.
Precise Autofocus Tracking with Instant Response
Reliable and responsive autofocus is delivered through the lens’ four XD (extreme dynamic) linear motors powered by advanced control algorithms. This smooth performance system provides accurate and quick focus tracking, often essential in many professional use cases like weddings and sports. This lens is fully compatible with Sony’s Alpha 9 III‘s high-speed continuous shooting capabilities of up to 120 frames per second3 with AF/AE (autofocus/autoexposure) tracking, even while zooming.
Designed for High-Performance Video Shooting
Along with its F2 aperture, the zoom range of the 28-70mm G Master provides a versatile video option that can cover standard field-of-view shots and tighter compositions up to 70mm. This lens minimizes focus breathing through its build and compatibility with the Breathing Compensation feature on various Alpha bodies4. Its high autofocus performance ensures reliable focus even when recording in high frame rates up to 4K 120p / FHD 240p5. Additionally, the XD linear motors and newly developed aperture unit operates silently, preventing any lens noise from being captured during filming.
The lens is ideal for gimbal use with a minimal zoom extension of approximately .68 inches. The compact form factor and short external zoom helps maintain gimbal balance, even at varying focal lengths.
Operability and Reliability for Versatile Control
Key control features include Linear Response MF for intuitive manual focusing, adjustable zoom ring torque, and an aperture ring with a click ON/OFF switch. The lens also offers two customizable focus hold buttons, an iris lock switch, and an AF/MF switch. The 28-70mm F2 G Master has an 86mm filter diameter and a convenient window on the lens hood for variable filter adjustments.
For durability, all buttons and switches are sealed with silicone gaskets, and critical areas are designed to resist dust and moisture6. This ensures reliability, even while using in challenging outdoor environments. Additionally, a fluorine coating on the front element repels contaminants for easy cleaning.
Pricing and Availability
The 28-70mm F2 G Master will be available in December 2024 for approximately $2,899.99 USD and $3,999.99 CAD. It will be sold at a variety of Sony’s authorized dealers throughout North America.
