Fujifilm X-S20 review


Product photos by Shaminder Dulai and Brendan Nystedt

Fujifilm has debuted its enhanced midrange APS-C mirrorless model, the 26MP Fujifilm X-S20. This interchangeable lens camera has improved video features and a new vlog mode, but doesn’t stray from the original very much. The X-S20 retains the deep grip, approachable design, plentiful ports, and in-body image stabilization of the X-S10 (though its grip hides a bigger battery), making for a well-rounded new camera for beginners and intermediate shooters alike.

Key specifications

  • 26MP X-Trans BSI-CMOS sensor
  • 5-axis in-body image stabilization (CIPA-rated to 7 stops)
  • On-sensor phase detection
  • 3″, 1.84M-dot fully articulating touchscreen
  • 2.36M-dot OLED electronic viewfinder
  • 20 fps burst shooting (up to 30 fps with a crop)
  • DCI and UHD 4K at up to 30p with 10-bit F-Log and F-Log2 support
  • External mic and 3.5mm headphone socket
  • 750 shots per charge using LCD
  • USB power delivery support
  • Single UHS-II card slot
  • Wi-Fi + Bluetooth
  • Compatibility with FAN-001

The Fujifilm X-S20 will be available from June 29th with a recommended price of $1299 body-only. Two kit options will be available, one with the XC15-45 for $1399 and another with the XF18-55 for $1599. This is a $300 price increase from its predecessor, the X-S10.

What’s new

A bigger mode dial makes room for a Vlog mode. Larger buttons should be easier to press without looking, too.

A quick look at the spec sheet tells us that the Fujifilm X-S20 is a lot like its predecessor. It has the same 26MP X-Trans sensor, a slightly improved in-body stabilization system, and a very similar overall design. But look closer and the subtle changes start to pop out. Many buttons and dials are repositioned or larger to make them easier to press. The grip has grown a tad larger to fit a bigger battery. There’s a flap for a headphone jack underneath the palm rest. And more differences start to appear once you dig into the menus and twist the mode dial.

Video upgrades

An upgraded X Processor 5 gives the biggest boost to the new model in its video capabilities. That means in-body 4K/60 4:2:2 10-bit internal is now on the table, as is open-gate (3:2 aspect) 6.2K. Fujifilm has also included is the F-Log2 color profile, giving users a Fujifilm-rated additional stop of grading potential at its base ISO of 1250. If you want to use an external HDMI recorder, the camera can now output to ProRes RAW or Blackmagic RAW if desired.

With the right accessories, the X-S20 becomes a fully-featured video shooting machine.

If you’re thinking that this is starting to seem like a mini X-H2, then you’re on the right track. The X-S20 adds compatibility with that camera’s cooling fan, the FAN-001, which screws onto the back of the X-S20 with ease. Also new in this model is a headphone jack, eliminating the need for a USB-C to 3.5mm adapter.

Continuous record time is a bit of an issue for the camera on its own, lasting only 36 minutes in the demanding 6.2K mode when tested by Fujifilm at 25°C (77°F). With the FAN-001 attached, runtime more than doubles to 78 minutes.

A new ‘1080/60P LP’ mode is designed to make extended recording easier on the camera. By using a 1.29x crop and thus a smaller portion of the image sensor, the processor can take a break from binning or line skipping; this mode nets you 32 minutes recording in 40°C (104°F) heat, or 78 minutes equipped with the FAN-001.

Vlog mode and UAC webcam

Conveniently located on the mode dial, Vlog mode brings a new video shooting interface to the Fujifilm system. This is designed to make typical kinds of content creator work easy and accessible. Tap the Vlog button on the touchscreen, and you get six quick-access buttons for common features like stabilization, the self-timer, eye/face detection, a product priority mode (that makes the autofocus snap onto objects held towards the lens), a high-speed recording toggle, and a background defocus mode (that opens the lens up as much as possible). The X-S20 also shows the user it’s filming with a red box around the LCD preview, or a green one if high-speed footage is being captured.

If you’re less of an aspiring YouTuber and more of a Twitch streamer, then the X-S20 can be used as an impressive webcam. Using the USB-C port, you can output a 4K/60p live stream from the camera. And unlike older Fujifilm models, the XWebcam software isn’t necessary, since the X-S20 relies on the UAC standard.

Autofocus and subject detection improvements

Stills shooters also get some extra help thanks to the faster X Processor 5 inside the X-S20. Fujifilm claims to have added an improved autofocus algorithm, developed originally for the high-end X-H2S model, so moving subjects and smaller subjects in particular should be captured with higher reliability.

The X-S20 also inherits the X-H2 family’s subject detection modes. In PASM or custom modes, these can be individually selected. You can pick from Animal, Bird, Automobile, Motorcycle & Bike, Airplane, and Train modes. If you shoot in full Auto mode, the camera will attempt to recognize and apply the correct mode based on the subject in the frame.


How it compares

As the market of vlog-friendly cameras blossoms, hybrid shooters have a wide array of models to choose from at a surprising range of prices. Here we’ve compared the Fujifilm X-S20 to some of its APS-C competition. Though the X-S20 sits at the high end price-wise, it comes with a commensurate amount of features and seems like a good value overall.

Weight 491g (17.3oz) 405g (14.3oz) 493g (17.4oz) 426g (15oz)

We can see that although it’s bested in a few minor specs, there’s one standout area: its video capabilities (particularly the open gate 6.2K option) are beyond what most mirrorless competitors offer, which becomes doubly effective coupled with its strong battery. The Canon EOS R10, for instance, still maintains a good lead in continuous shooting, but has less than half the CIPA-rated battery life of the X-S20. The inexpensive vlog-centric Nikon Z30 might be good for those with 1080p video needs, but Fujifilm’s option is in a different class altogether.


Body and handling

While the X-S20 seems a dead ringer for the X-S10, it improves on the original design in subtle ways.

The Fujifilm X-S20 is hardly a shouty camera, choosing a subdued style that focuses on functionality over visual appeal. With its compact size, DSLR-style grip, and dual control dials, it’s approachable – it looks like an average camera. Appropriately, it’s the functional touches that have been adjusted on the body. Compared to its predecessor, many of the controls have been enlarged, with bigger dials and more pronounced buttons, while retaining the satisfyingly clicky rear joystick. The articulated touchscreen gets a small bump in resolution, while the electronic viewfinder, with its small OLED panel, is the same as in the X-S10.

The keen-eyed among you will recognize the two holes and small plug behind the rear LCD. Cribbing from the X-H2 models, the X-S20 can accept Fujifilm’s FAN-001 accessory, which adds a cooling fan to the camera. This is a pricey accessory at around $200, but it can let the X-S20 shoot video for double the default duration and provide reliability in higher temperatures.

Thanks to the addition of a real headphone jack on the grip, the USB-C port can be used to power the camera while you monitor the audio.

Fujifilm has clearly tried to bolster everything photographers liked about the X-S10, including its port selection. It has a USB-C with power delivery for charging, a micro HDMI and a 2.5mm microphone jack that also can accept a wired shutter release. On the grip, there’s a brand-new 3.5mm headphone terminal. In the X-S10, users needed to use a USB-C to 3.5mm adapter, but X-S20 users can plug in directly.

The Fujifilm X-S20 has a battery that can achieve a rating of 800 shots on a single charge, in the right mode.

Apart from the upgraded processor, the biggest internal change is shifting from the smaller, 8.7Wh NP-W126 battery to the 16Wh NP-W235 battery. This almost doubles the battery capacity: the CIPA-rated shot count on a single charge goes from 325 shots all the way to 750, or as far as 800 when using the camera’s Economy power setting. In order to accommodate this bigger battery, the camera’s grip is slightly larger, which makes the camera a bit more comfortable to hold. As usual, it’s not uncommon to achieve twice the CIPA-rated value.

Next to the battery is the upgraded UHS-II SD card slot. While you only get the one slot, and it’s more or less in the same spot, the uprated interface will be a boon for burst shooting. With a fast SD card, Fujifilm says the X-S20 can shoot more than 1,000 JPEGs or compressed Raw files at 8 fps.


Image quality

Our test scene is designed to simulate a variety of textures, colors and detail types you’ll encounter in the real world. It also has two illumination modes to see the effect of different lighting conditions.

Like we’ve seen in other recent 26-megapixel Fujifilm cameras, image quality is very good from the X-S20. All in all, you’re basically getting image quality on par with the discontinued X-T4 – Fujifilm’s still and video flagship from three years ago – which retailed for hundreds more. It’s competitive with its peers, as well, showing similar image quality to the Canon EOS R10, Sony a6600, and Nikon Z fc.

Colors are typical of Fujifilm in the default profile, giving subjects just a bit of pop without looking overly garish. Reds, in particular, aren’t as bright as those from Nikon or Canon. Of course, if you’re buying a Fujifilm, you’ll want to experiment with its signature film simulation modes, as JPEGs from the X-S20 can look very stylish if you don’t want to fuss with developing Raws.

Dynamic range

Like its predecessors, the sensor in the X-S20 is somewhat of a known quantity as it’s been turning out great images for a few years now. While it’s of a previous generation and lacks whizzy new sensor technologies, it has plenty of dynamic range and will let you underexpose your photos to protect highlights, without sacrificing information in the shadows.


Autofocus

Although the sensor is old hat, the X-S20 adds faster processing which directly impacts autofocus performance and features. You can expect fairly good performance, but accuracy is very much tied to subject detection modes. If you’re shooting a moving subject, definitely switch over to the camera’s face detection mode to keep your subject in focus more reliably. The subject detection modes we tried worked well but is still somewhat prone to false positives, particularly in human face detection mode.

In our continuous AF test, we found that straight-line performance with face detection on or off was fairly similar, only starting to lose focus as the subject got closer to the camera. This is what we’d expect: the riding directly approaching the camera is simply meant to test the camera’s ability to measure and predict subject distance, and to drive the lens to the correct focus distance.

But in a zig-zag, the subject was sometimes lost as the rider changes direction: a challenge for the camera as the rate of approach varies. The hit rate was pretty good, and the camera didn’t try and refocus on the background, as some previous Fujifilm models have, but there are shots that are noticeably a bit out of focus as the X-S20 struggles to anticipate the movement. On the whole, Fujifilm’s AF is still behind competitors like Sony, with its a6700 featuring far better subject tracking.


Video

The ability to add a fan to the back of the X-S20 means you can add the ability to shoot for long periods more reliably but that stills-only shooters don’t incur any expense or bulk. Having to keep the screen extended when the fan is attached is a but awkward, though.

Video is where the Fujifilm X-S20 picks up some new tricks from the company’s X-H2 cameras. Not only will this shoot great-looking 4K at a number of standard frame rates, but it also picks up a 6.2K open-gate mode, perfect for cropping later into wide-and-tall aspects for all matter of social media. The X-S20 resolves a little less detail than the Sony a6700, but not by a whole lot and should still look great once uploaded to social media.

The provision of the attractive ‘Eterna’ color mode also helps give a stong starting point for making attractive video.

For more advanced videographers, you have access to the Eterna and F-Log color profiles, as well as Hybrid Log Gamma. That means you’ll be able to grade this footage after the fact to get the look you want.

Rolling shutter

Rolling shutter results we measured from the X-S20 were around the same as the X-T4. That means that in UHD 4K, when shooting 60p footage, you can expect 16ms, and when shooting 24p footage it’s more like 20ms.

If you want to use the 3:2 aspect open-gate mode at 6.2K/24p, which uses the full height and width of the sensor, you can expect a slower response time at 24ms. That’s far behind the stacked sensor of the pricier X-H2S, which clocked in at 6.2ms. This might sound worrying bad, but if you only use a crop of the frame, there’ll be less of a lag between the top and bottom of your shot (as you’d expect, a full-width 16:9 crop would take around 20ms, while a native UHD crop would take a mere 12.5ms).

All of these results are very good, and as long as you aren’t shooting very fast subjects, you shouldn’t see much rolling shutter “jello” effect in your video.


Conclusion

What we like… What we don’t…
  • Great image quality
  • Compact size
  • Impressive video features
  • Solid battery life
  • Good burst shooting speed
  • Approachable control setup
  • Fair price
  • Headphone and mic jacks
  • Autofocus trails competitors
  • Small electronic viewfinder
  • AF joystick inconveniently placed for some users
  • Small ∼2 sec buffer makes 20fps shooting less useful

The bottom line is that Fujifilm’s X-S20 gives you a lot of value for the money. Although it’s a little more expensive than (and a dead ringer for) the previous X-S10, this is a meaningful upgrade in most regards – especially if you’re hoping to capture video with it. The battery life makes it a competent companion for day-long shoots without having to hassle with USB-C charging or spare batteries.

Subject detection modes can come in handy, like when shooting trains or airplanes. Auto mode can apply subject detection without user intervention.

That’s not to say it’s a perfect camera. Fujifilm still is behind its competitors (specifically Canon and Sony) when it comes to tracking and keeping high-speed subjects in focus. Looking at the marketplace around the X-S20’s price, you absolutely need to weigh your needs when it comes to autofocus – around the same MSRP you can get competing options with far more reliable subject tracking. Oh, and that itty-bitty viewfinder is fine in a pinch, but it’s in need of a replacement the next time around.

The 26-megapixel X-Trans sensor is a little older, but can still output gorgeous images with vivid colors.

All of that said, if lenses are what you’re after, and you’re eager to pick up some unique prime lenses, Fujifilm has a leg up in that department. Between Fujifilm’s appealing film simulations and the diversity of lenses available, the X-S20 will be the pick for those who like to march to the beat of their own drum but don’t want to compromise on image quality.

“If you’re on the hunt for your first ‘real’ camera, the Fujifilm X-S20 is an extremely appealing package.”

If you’re on the hunt for your first ‘real’ camera, the Fujifilm X-S20 is an extremely appealing package. Especially when paired with the superb 18-55mm F2.8-4.0 kit lens, this is a camera that gives you most of Fujifilm’s best technology for not a whole lot of dough. It might not have the distilled sex appeal of the tre chic X100V, but the X-S20 packs a powerful performance punch.

The autofocus and viewfinder stop it achieving our highest award, as it undermines its appeal to the general customer, but they don’t stop it being one of our favorite photographer’s cameras in its class.

They may look incredibly similar, but the X-S20 is a big upgrade from the previous generation.

Scoring

Scoring is relative only to the other cameras in the same category. Click here to learn about what these numbers mean.

Compared to its peers

The Fujifilm X-S20 is a better-rounded camera than either the cheaper Canon EOS R10 or the slightly more expensive, higher-performance EOS R7. While the Canon cameras have more modern autofocus, a big pitfall is the lack of lenses in the Canon EOS RF-S system. While you can get plenty of full frame lenses, smaller, optimized-for-APS-C options are few and far between – and you’ll have to get them only from Canon. Fujifilm’s X-mount system is focused on APS-C and has a wide array of lenses to choose from, giving you a lot of choice.

Sony’s lens selection, on the other hand, is quite good, and the competing a6700 is a real tough comparison. This has a faster-readout version of the same 26MP sensor as the X-S20, but with more sophisticated autofocus supporting it for shooting fast action. Plus, Sony’s lens lineup is impressive, as it has been making APS-C mirrorless cameras longer than anyone, so there are options for most types of photography. Sony’s offering is the logical one to pursue, but the Fujifilm X-S20, with all its flaws, still has a certain character that sets it apart.

The cheap-and-cheerful Nikon Z30 is a tempting option for beginners. Its autofocus tracking is a little more reliable than the X-S20, though it lacks the X-S20’s subject recognition, so it’s a little slower to use. It’s a similar story with the Z50 and Zfc but both cameras lack in-body stabilization and their video features are far behind those of the Fujifilm X-S20. The range of APS-C lenses for Nikon’s Z-mount is improving, but Fujifilm still has the much better selection on the whole, giving you more room to grow as a photographer.

Adobe Max Roundup: the demos

Adobe Max Roundup: the demos


Photo: Mitchell Clark

This year we attended Adobe Max in person, where we got to demo several of the new features in Photoshop, Lightroom, and Adobe Camera Raw. If you missed the announcement, you can read our coverage of it here, though we’ll be covering the hits here.

We documented the demos on our Instagram, but in case you missed it, we’re rounding them up here. We were also able to interview some folks at Adobe while at the show, so stay tuned for more on the future of Photoshop, Lightroom, and other Adobe projects like Content Credentials.

Adobe Camera Raw Adaptive profile

Adobe has added a new profile to Adobe Camera Raw, called Adaptive. It uses AI to analyze what’s in the scene, and adjust exposure, tones, saturation, and other parameters automatically, potentially giving you a better starting point for your own edits. It’s also designed to work with HDR images and produces both HDR and SDR profiles, making it even more useful for those who aren’t used to editing for HDR displays yet.

Since it’s substantially more opinionated than other profiles like Adobe Color or Adobe Landscape, there’s also an amount slider that lets you tone down or turn up the results.

Photoshop automatic distraction removal

Perhaps one of the niftiest features Adobe added to Photoshop is the automatic distraction removal tool. It analyzes your photo for cables, wires, or people that may be in the way of your subject, then automatically fills in the areas they took up.

Lightroom Quick Actions

Lightroom’s new Quick Actions, available on Mobile and Web, will automatically mask parts of your image like subjects, backgrounds, and skies, and let you make adjustments to them.

Lightroom Frame.io integration

Frame.io is now built into Lightroom, letting you access images uploaded to the cloud service. Combine that with Frame.io’s Camera To Cloud feature, available on some Fujifilm, Panasonic, Nikon, Canon, and Leica cameras, and you can take pictures on your camera then watch them appear wirelessly in Lightroom.

Content Credentials

Adobe’s Content Credentials system is part of a larger industry-wide initiative to help prove what content on the web is authentic, and to keep track of what edits have been made to it. While at Max, we got to take a look at the Chrome extension meant to surface the credentials attached to images on social media and other sites, as well as the closed beta site that lets you attach content credentials to your own images, and view what credentials are attached to existing images.

We got to sit down with one of the senior directors of the Content Authenticity Initiative at Adobe while at the conference, so expect a more thorough check-in of the technology to come.

Generative Extend in Premiere Pro

Photoshop has had several generative AI features in beta for a while now, but now Adobe has introduced one for its Premiere video editing software. It lets you extend a clip by up to two seconds, helping you fill in gaps, transitions, or slightly flubbed takes with imagery generated by Adobe’s Firefly model.

According to Meagan Keane, Principal Product Marketing Manager for Adobe Pro Video, the idea came from asking customers what some of their biggest editing pain points were. The Pro Video team was then able to take that to the research team, and the result is Generative Extend.

On this day in 2014: The Panasonic GH4, which brought 4K to the masses, reviewed

As part of DPReview’s 25th anniversary celebration, we’re looking back at some of the more significant cameras to come along over the past 25 years, and today, we’re highlighting the camera that led the 4K revolution in consumer cameras: the Panasonic GH4. Officially announced in early 2014, we published our GH4 review on October 16, 2014 – ten years ago today.

We’ve all become so used to 4K video that it no longer registers as unique. It’s found on virtually every mirrorless camera made today, smartphones, action cameras, miniature gimbal cameras, webcams, security cameras, and even those wacky $100 ‘pro’ video cameras you see on Amazon and wonder who buys them.

But, of course, it wasn’t always that way, and we have the GH4 – the first mirrorless camera to capture 4K video internally – to thank for opening the metaphorical floodgates and ushering in the 4K era.

I had a personal interest in the GH4: as someone who had adopted the GH line early on for video projects, I was as curious as anyone to know how it stacked up. Although I was on staff at DPReview, I wasn’t involved in writing the GH4 review and probably read it with as much anticipation as anyone else.

It’s worth remembering that the GH4 was a hybrid camera designed to appeal to both stills and video shooters, and it had features to appeal to those who wanted to do both. Like the GH3, the camera was built around a 16MP sensor, but it supported 12fps burst shooting (7.5fps with focus tracking), a 1/8000 shutter speed and 1/250th flash sync. It even had a rather lovely 2.36M-dot OLED viewfinder.

But realistically, nobody was buying a GH4 just to shoot stills. You bought it because you wanted a solid video camera that could shoot stills when needed.

“Realistically, nobody was buying a GH4 just to shoot stills.”

The GH4 could capture 4K video at up to UHD 4K/30p (3840×2160) or DCI 4K/24p (4096×2160) internally and supported both Long GOP and All-I codecs at bit rates up to 200Mbps. Although we take bit rates like this for granted today, this was very high at the time. The camera also produced pleasing 1080p video, though as we called out in our review, its HD video wasn’t as good as the perfectly oversampled 1080p video from the Sony a7s.

Despite the impressive specs and beautiful video to match, we had some nitpicks. To start, 4K video captured internally only had 8-bit 4:2:0 color, providing less flexibility for color grading in post. (10-bit 4:2:2 color was supported, but only when recording externally.) Additionally, the GH4’s sensor was 4608 pixels wide, requiring the camera to use a smaller, native crop of the sensor when shooting 4K. This resulted in a 1.1x crop for DCI 4K and a 1.2x crop for UHD 4K.

Equally as crucial as its video specs, the GH4 illustrated Panasonic’s commitment to supporting a professional video workflow.

The camera included several now-common tools to improve the video shooting experience, including focus peaking, two zebra settings, control over Master Pedestal (black level) and luminance scale, and a ‘cinema-like’ gamma preset. It also allowed users to set the shutter speed and ISO as shutter angle and gain and could generate color bars for calibration. It was also possible to switch between capture frequencies, meaning the camera could support NTSC, PAL, and true 24fps cinema standards.

“Equally as crucial as its video specs, the GH4 illustrated Panasonic’s commitment to supporting a professional video workflow.”

Alongside the camera, Panasonic released the optional DMW-YAGH interface unit. This $1999 accessory unit added two XLR inputs for audio, an SDI input for timecode, four 3D-SDI connectors capable of outputting 4:2:2 10-bit video and a 12V DC power socket. The unit attached to the bottom of the GH4 and felt oversized relative to the camera. Beginning with the GH5, the interface unit was phased out in favor of the DMW-XLR1, a much more affordable option in the style of the hotshoe-mounted XLR adapter we’ve become accustomed to today.

The GH4 was also the camera Panasonic used to debut its newest autofocus technology: Depth-from-Defocus, or DFD. DFD attempted to build a depth map of a scene by making tiny focus adjustments and analyzing changes in the image. With an understanding of the out-of-focus characteristics of a particular lens, the camera could build a depth map of the scene.

The optional DMW-YAGH ‘Interface Unit’ provided a more extensive selection of video industry connectors for using the GH4 as part of a high-end video rig.

However promising the technology may have been, DFD never quite met expectations. Panasonic really wanted to make it work, and it’s possible that, given fast enough sampling and processing, it might have continued to improve. Unfortunately for Panasonic, cameras using phase-detect autofocus consistently provided a better AF experience, particularly when shooting video, and the company eventually made the jump to phase-detection with the Lumix S5II in 2023, finally arriving in the GH series on the GH7 in 2024.

In our review of the GH4, we found a lot to like and a few frustrations. For example, despite having an autoexposure compensation dial, the camera didn’t allow you to use it when using Auto ISO in manual exposure mode, and there was no Auto ISO option when shooting video in M mode. Overall, though, we were mighty impressed and saved our biggest praise for the camera’s video capabilities:

“The GH4 was also the camera Panasonic used to debut its newest autofocus technology: Depth-from-Defocus, or DFD.”

“It’s in terms of video that the GH4 really stands out. It produces some of the best video we’ve yet seen – losing out only to the Sony a7S’s moiré-free 1080 output. The ability to capture good quality 4K, whether for use at full resolution, downsampling to 1080 or cropping to 1080, adds real flexibility to the camera. Low light performance is solid if not exceptional,” we concluded.

The GH4 landed in the retail market at a price of $1699, or about $2260 today adjusted for inflation, which isn’t far off the $2199 price of the GH7. It’s amazing to think about how expectations for video have changed over the years. However, the GH7 has its work cut out for it: rather than being an obvious standout in the crowd, it has to compete in a marketplace of cameras brimming with video features. Maybe in another ten years, we’ll look back to see how it held up.

DJI has announced the Air 3S, an update to its existing dual-camera Air 3 model that upgrades the primary camera to a larger Type 1 sensor and adds features that promise to make the drone easier to operate at night. DJI is positioning the Air 3S as “perfect for travel photography.”

The main camera on the Air 3S gains a 50MP Type 1 (13.2 x 8.8mm) CMOS sensor and features a 24mm equiv. F1.8 lens. That’s an upgrade from its predecessor, which utilized a smaller Type 1/1.3 (4.8 x 3.6mm) CMOS sensor with a marginally faster F1.7 lens. The telephoto camera remains unchanged between the two models, using a 48MP Type 1/1.3 sensor and featuring a 70mm equiv. F2.8 lens.

In addition to stills, both cameras can capture up to 4K/120p or 4K/60p when shooting HDR. All video can be captured in 10-bit, even in regular color mode, and D-Log M and HLG modes are available. The maximum ISO has been raised to 12,800 (3200 when shooting D-Log M). However, DJI says the Air 3S includes a new, more advanced video encoding algorithm that reduces video file size by over 30% without compromising image quality.

DJI claims both cameras can capture up to 14 stops of dynamic range and says the new main camera should capture even more detail than the camera on its more expensive Mavic 3 Pro model.

The DJI Air 3S is similar to its predecessor, the Air 3, but it gains a larger Type 1 (13.2 x 8.8mm) CMOS sensor on its main camera.

Beyond the cameras, DJI has added several appealing features to the Air 3S:

A new Free Panorama mode enables users to create panoramic shots by stitching together images across a manually selected subject area. This works with either camera, but DJI suggests the best results will come from using the telephoto camera, which reduces distortion.

The Air 3S also includes features designed to make it easier and safer to fly at night, including Nightscape Obstacle Sensing, with the Air 3S becoming the first DJI drone to feature forward-facing LiDAR. Additionally, the drone includes downward-facing infrared sensors and six vision sensors (two each at the front, rear and bottom). According to DJI, this combination of sensors provides the Air 3S with “nightscape omnidirectional obstacle sensing,” which should allow the drone to automatically identify and navigate around obstacles for safer nighttime photography.

This technology also enables DJI’s next-gen Smart RTH (return-to-home) feature, intended to allow the drone to return safely to its takeoff location, even at night.

The Air 3S is available with either DJI’s RC-N3 controller, which requires a smartphone to monitor the camera feed and aircraft status, or the RC 2 controller (above), which includes a built-in 700-nit 5.5″ 1080 screen.

The Air 3S also includes real-time vision positioning and map construction technology, designed to allow the drone to memorize a flight path and to return safely when adequate light is available, even in areas without satellite coverage.

The new model also features DJI’s ActiveTrack 360 subject tracking but introduces a new subject focusing feature designed to keep a subject in sharp focus, even during manual flight or when a subject moves off-center. This should allow a pilot to focus on creative decisions like composition or camera movement while ActiveTrack keeps the subject in focus.

There are a few hardware specs worth noting as well. The Air 3S weighs 724g (1.6 lbs), just 4g more than its predecessor, and is rated for 45 minutes of flight time. It includes DJI’s O4 video transmission system that transmits 10-bit video at up to 1080/60p and 42GB of built-in storage. A new Off-state Quick Transfer feature allows files to be transferred from the drone to a smartphone or a computer even when powered off.

Finally, for the privacy-conscious, a new Local Data mode completely disconnects the drone from the internet, ensuring that all data stays only on the device. DJI likens this mode to airplane mode on a smartphone.

The Air 3S is available in several packages. The Fly More combo shown above includes the RC 2 controller, ND filter set, two additional batteries (for a total of three), a charging hub, extra props and a shoulder bag, will retail for $1599.

The charging hub that ships with the Air 3S supports PD fast charging and features a power accumulation function. It allows users to transfer the remaining power from several depleted batteries into the battery with the most remaining power – something anyone who has had to use drones in remote locations without a charging station is likely to appreciate.
