Sony a7 IV initial review

The Sony a7 IV is the fourth generation of the company’s core a7 full-frame mirrorless camera model. It’s the most advanced yet, bringing many of the improvements Sony has made in terms of autofocus and interface design since the launch of the a7 III, back in February 2018.

Key Specifications

  • 33MP BSI CMOS full-frame sensor
  • Up to 10 fps shooting in lossy Raw with extensive buffer
  • In-body stabilization rated up to 5.5EV
  • Full-width oversampled 4K from 7K, up to 30p
  • 4K/60p with Super35 / APS-C mode
  • 10-bit video or HEIF stills capture
  • H.265 video, S-Cinetone color mode
  • 3.69M dot OLED viewfinder
  • Twin card slots (1x CFe A/UHS-II, 1x UHS-II SD)
  • Full-time Bluetooth LE connection

The a7 IV sees just about every one of its specifications improved over the a7 III, from basics such as the resolution of the sensor and viewfinder to significantly increased video capture options.

The a7 IV will be available from late December 2021 at a recommended price of $2499, a $500 increase over the launch price of the a7 III.


What’s new

33MP BSI-CMOS Sensor

At the heart of the a7 IV is a new 33MP BSI-CMOS sensor. This represents a move away from the 24MP chip used by the a7 III and its immediate Panasonic and Nikon rivals. Given that BSI sensors are already widely used in the current generation of cameras, we’re not expecting huge leaps forward in image quality. A slight uptick in detail and comparable low light performance is the most likely thing we can expect, in terms of image quality.

Despite the higher resolution, the a7 IV can still shoot at 10 frames per second. However, it can only do so in the lossy compressed format if you want to shoot Raw. The a7 IV has a lossless compression option, for when you need maximum processing flexibility, but the burst rate drops to around 5 fps if you use it. Sony says the camera’s buffer depth allows over 800 Raw+JPEG images (or over 1000 JPEGs), but this is in the uncompressed Raw format, which again shoots at around 5 fps.

Our first look at the rolling shutter rates suggest this isn’t an especially fast sensor. 14-bit readout of the whole sensor for stills takes around 1/15 sec (~66ms), which is around seventeen times longer than the super-fast a1 takes to read out its sensor. This means silent shutter mode is likely to result in significant distortion with moving subjects.

Full-width 4K video takes around 26.5ms, which is comparable with the other models in its class. It’s likely the camera is dropping to 12-bit readout for video mode, but the process of combining pixels should reduce noise and hence prevent DR dropping to ~12EV. 60p footage has rolling shutter rate of around 12.8ms, which is low enough to avoid distortion of all but the fastest movement.

Autofocus

In terms of autofocus, the improvements over the a7 III should be fairly significant, not so much because of the promise to focus in conditions that are one stop darker (–4EV with an F2 lens) but because that camera was one of the last Sonys that didn’t integrate Eye AF into its main AF system, and relied on a much more primitive AF tracking system. The a7 III could detect human eyes, but it couldn’t seamlessly and dependably switch between eye, face and body tracking, if you set the camera to focus on a person.

The a7 IV does exactly this, and has modes that can detect and more accurately track animals, include birds, dogs and cats. For the first time, these animal detection capabilities extend to the camera’s video mode, too.

The a7 IV still offers a dizzying array of AF area modes (including ‘tracking’ variants of each), but you can at least disable all the ones you don’t use. The tracking versions are unavailable in video mode: instead you tap the rear screen to select a subject for the AF to follow.

The simplicity of the system makes it difficult to convey just how effective it is. But like Canon’s latest AF system, you need only indicate to the camera what you want to focus on and it’ll use the most appropriate of its powerful AF algorithms to maximize your hit rate. Until you’ve used a system like this, or the comparable one in recent Canon cameras, it’s difficult to appreciate how powerful, reliable and simple they can be.

Video

Movie mode gets its own switch, rather than being part of the exposure mode dial. The camera lets you choose different settings (WB, color mode), custom button layouts and Fn Menu options for stills and video modes but exposure values are carried between the two.

Breathing compensation

The a7 IV adds a Breathing Compensation mode that crops and resizes the video to cancel-out any change in a lens’s angle-of-view (AoV) as it focuses. The mode only works with select Sony lenses (all the GM lenses and some G series glass), as the camera needs a profile of the breathing characteristics. Video is cropped to match and maintain the narrowest AoV that might occur if you focused from minimum focus distance to infinity, meaning there’s no distracting change of framing as you refocus.

After autofocus, the biggest area of improvement is in terms of video capability. The a7 III was the first a7 model to offer 4K capture. Its implementation was pretty good for early 2018, with oversampled 24p capture from the full width of its sensor but a crop required for 30p shooting. All footage was captured in 8-bit precision, at relatively modest bitrates.

The a7 IV moves things forward considerably, adding 10-bit capture to increase the processing flexibility of Log footage and to allow full Hybrid Log Gamma (HLG) capture for playback on HDR TVs.

It also gains the ability to shoot 4K/60p for action capture or slow-mo work, but this requires a crop to APS-C/Super 35 dimensions. There are also options to use H.265 compression (XAVC HS) and apply the S-Cinetone color profile.

Eye AF is now available in video mode, which should substantially increase the degree to which you can depend of autofocus staying on your chosen subject. As in stills shooting mode, the camera has been trained to recognize humans, animals and birds.

However, while you can set video mode to use different color and white balance settings, define separate button setups and Fn menu layouts for stills and video, the camera still carries its exposure settings over from stills to video shooting, which isn’t always ideal.

Live streaming

A fully articulating screen can be useful for waist-level shooting, vlogging or selfies. It also allows you to monitor the camera if you’re using its streaming mode.

The a7 IV also offers the ability to live stream video over its USB connection using the audio and video standards (UVC/UAC) that are part of the USB standard. This allows a choice of HD or FullHD resolutions with FullHD available at up to 60fps. There’s also a 4K option but this only supports 15 frames per second, which gives a dreadful stop-motion look to the footage. Connection is designed to be as simple as possible, using the Imaging Edge Webcam software for Mac or PC. A connection via smartphone is also possible, though audio may not be available at resolutions above HD (720).

HEIF 10-bit stills

The a7 IV gains the ability to capture 10-bit compressed images, rather than just the 8-bit JPEGs historically offered. Unlike Canon, which only uses HEIF capture for HDR images, the Sony lets you shoot standard DR images in 10-bit, with a choice of 4:2:2 or 4:2:0 chroma sub-sampling, if you can find benefit to doing so.

The downside of this added flexibility is that you need to engage HEIF capture before you can engage the Hybrid Log Gamma (HLG) color/gamma mode, rather than having both settings change to match one another. It’s worth trying, though: images shot in HLG can show much more of the camera’s dynamic range to give a much more lifelike version of your image, if viewed with an HDR-capable TV.


How it compares

The a7 IV becomes the most expensive iteration of the a7 model yet, with a price that makes it among the most expensive of its peers. We’ve lined it up next to the similarly priced EOS R6 and the significantly cheaper Nikon Z6 II. Panasonic’s Lumix DC-S5, which we didn’t have space to include, offers a pretty similar video spec (10-bit 4K capture, including 60p from its APS-C crop) but its autofocus isn’t quite as effective. Like the Nikon, thought, it’s markedly less expensive.

We’ve included the a7 III to show what the a7 IV gains over its predecessor but there’s also the smaller, less expensive a7C that shares most of its specs with the a7 III. The only major difference is that the a7 C has a slower flash sync speed and a smaller but higher resolution viewfinder. The a7C has a newer AF system than the a7 III, so its performance and usability will be a little more like that of the new camera.

This table should make clear that the a7 IV is well specced, but not to the point of standing out from its less expensive rivals. As such, it’s going to be the real-world performance of the AF system, the degree of rolling shutter in its 4K footage, and its ability to maintain its 10fps burst rate for many hundreds of images that will need to set it apart.


Body and controls

The shoulder dial (with the toggle-lock shown in its unlocked state) controls exposure comp by default, but is now unmarked and can be set to control other functions.

The a7 IV appears to share its body with the a7S III, which offers a series of refinements over the previous a7 model. The grip is slightly deeper, the joystick on the back is improved and there’s a full-size Type A HDMI socket on the side of the camera.

A further improvement over the a7S III is the move to an unmarked lockable dial on the shoulder of the camera, meaning it can be re-purposed if you don’t shoot in a manner that requires exposure compensation.

There’s also a fully-articulating rear screen. These aren’t to everyone’s taste but allow video, vlogging and selfie shooting in a way that a tilt-out screen doesn’t.

Both of the a7 IV’s slots accept SD cards (up to UHS-II type), with the top slot also having an inner recess that accepts CFexpress Type A cards. There’s only one slow-mo video mode that requires the use of CFexpress cards: everything else can be written to V90 SD cards.

The a7 IV still offers twin card slots: both accept UHS-II SD cards with the upper one also able to take one of Sony’s small CFexpress Type A cards, which can maintain much faster write speeds than the fastest SD cards (typically 400MB/s minimum sustained write, vs 90MB/s minimum sustained write for V90 SD cards).

The a7 IV also gains the white balance sensor from the a7S III, which should help deliver greater white balance consistency, even if you’re shooting tight-in on a brightly colored subject.

Improved UI

More than the ergonomic changes, we’re delighted to see the a7 IV gain the improved menus and expanded touchscreen utilization first seen in the a7S III. The menus now have their section tabs down the left-hand side of the screen, meaning you’re only ever a click or so away from being able to jump between tabs. They’re also touch sensitive, so you may not need to click or nudge anything at all.

This layout makes the menus much quicker to navigate, as do sub-section headings within each tab. The arrangement differs from previous Sony cameras but the underlying relationships between settings remain the same, so it shouldn’t take too long to familiarize yourself with the new system, if you’re an existing Sony user.

Constant smartphone connection

Sony has offered Bluetooth on its cameras for many years but has used it solely for transferring location data from smartphones. The a7 IV adds a constant-connection option of the type offered by most of its rivals. This means you only have to pair the camera with your smartphone once, after which they will automatically re-establish a Bluetooth Low Energy connection, making it much quicker and simpler to transfer images to your phone.

Closable shutter

The a7 IV gains the ability to close its mechanical shutter when the camera is turned off, helping to prevent dust build-up on the sensor. Shutter blades tend to be very lightweight, which also means they can be pretty fragile, so this should be seen as a dust prevention, rather than physical protection measure.

Battery

The a7 IV uses the same NP-FZ100 battery as the a7 III and other more recent Sony cameras. It’s a usefully hefty unit that, combined with the relatively modest viewfinder res, lets the a7 IV achieve a CIPA battery life rating of 580 shots per charge using the rear screen and 520 shots per charge using the EVF.

As always, these figures are more useful for comparing cameras, rather than getting an idea of exactly how many shots you’ll get (in our experience, getting double the rated number isn’t unusual with a new battery). We tend to find a rating of over 500 shots per charge means not really having to worry about battery life in anything but the most intensive pro sports or wedding shoots.

As you might expect of a new camera, the a7 IV can be either charged or powered over its USB-C socket.


Initial impressions

Much has changed in the eight years since the original a7 was launched: with Sony now far from alone in offering a modern full-frame mirrorless camera. Technology has made huge leaps forward, too, with autofocus in particular improving in terms of speed, sophistication and simplicity, to the point that no one would now suggest DSLRs retain the upper hand.

Sony’s move to bigger batteries has had a huge impact on its cameras’ usability, and its ergonomics and user interface have been radically improved with each iteration. The video features have also expanded significantly, with the fourth a7 model bringing the series back into line with its competitors.

What’s clearly changed, in the meantime, is the positioning. The original a7 was launched at what was then a record low price for a full-frame camera: $1700, body only. Even taking inflation into account, that’d still be a hair under $2000 in today’s money. The a7 IV’s price is a significant increase over this, and it’s notable that Sony now offers the a7C for more price or size-conscious buyers. This provision of a relatively up-to-date sister model, rather than simply lowering the prices on outdated models is a welcome change. The a7C might not have the improved menus of the a7 IV but it doesn’t feel as unrefined and clunky as the Marks I and II do, by comparison to the latest cameras.

Owners of the first two a7 models, and even some a7R series users are likely to be stunned by how far the series has come in the past few years

This move allows the a7 IV to address the needs of more dedicated enthusiasts, and makes it a direct competitor to Canon’s very likable EOS R6. On paper, at least, it doesn’t go far beyond the Canon, though, so it’ll be interesting to see how they compare in real-world use. Of course, if Sony decides to continue the a7 III at a lower price, the waters get significantly muddier. The a7 III’s autofocus is recognizably more than a generation behind the new camera, but it isn’t made to look like a work-in-progress, the way that the older models were when the Mark III arrived. The a7 III still does very well at most of the things the a7 IV does, which could undermine the attempt to push the series upmarket.

Sony seems very keen to say that the a7 IV has gained many of its improvements from the flagship a1, which we think that risks implying a closer connection than actually exists. While it is not untrue that the a7 IV has some features that arrived with the a1, the new camera doesn’t have the Stacked CMOS sensor that provides the brute power underpinning the a1’s performance. In many instances, it’s fairer to point out that the a7 IV’s features are shared with the video-centric a7S III. Still not a bad thing to be able to claim, but perhaps setting more realistic expectations, in terms of how much star quality you expect to rub off on the more mass-market model.

Overall the a7 IV looks to be a very capable camera: one with much-enhanced video and more sophisticated autofocus. For newcomers the increased price, an array of credible rivals and the high bar set by the a7 III means it’s going to have its work cut out if it’s to stand out in the way earlier a7 models did. However, owners of the first two a7 models, and even some a7R series users are likely to be stunned by how far the series has come in the past few years.

Ulanzi’s 52mm MagFilter Magnetic Filters offers interchangeable filters for smartphones

Ulanzi’s 52mm MagFilter Magnetic Filters offers interchangeable filters for smartphones


Image: Ulanzi

Lens filters for smartphones are not a new concept. Designed to give photographers more creative and technical control over their images, there are several types on the market today that can control how much light comes into the camera, reduce reflections and flare or add more vibrancy to your images with different color tones.

Up until a few years ago, photographers wanting to add a physical filter to a smartphone would need to attach a clamped filter that sits at the top of the phone’s camera lenses or use a third-party smartphone lens with filters.

Although useful, clamps tend to be bulky and aren’t always the easiest to align with your camera. Third party lenses offer more accuracy, but good-quality options can cost in excess of $100, without the inclusion of filters.

Ulanzi aims to be different by offering a lightweight foldable adapter ring that snaps on to the center of your MagSafe compatible device or case, which the manufacture says leads to a quicker workflow and more accurate alignment of the filter to the camera lens on the back of the phone. On an iPhone 14 or 15 it works by magnetically attaching to the rear using Apple’s MagSafe attachment system.

For users without an iPhone, there are workarounds through the use of third-party smartphone cases with magnetic ring plates that emulating MagSafe. WIth such a case, you can attach Ulanzi’s adapter to the ring plate and use the filters as normal.

As we reported last week, the concept isn’t new. Tiffen recently released a similar product with its MagSafe 58mm Filter Mount. Both products approach a solution to adding filters in a similar manner but differ in design. The Ulanzi opts for compactness with a foldable design.

The Tiffen comes with one polarizing filter (you can buy other filters separately) at around $40. In contrast, the Ulanzi’s version comes as a kit for $219 with an ND filter, a polarizing filter, one soft focus filter and a selection of color effect filters. There’s a storage case as well. Having multiple filters packed in may be enticing to users seeking to experiment with different filters and want the simplicity of having them all packaged together.

Tamron announces 28-75mm F2.8 Di III VXD G2 for Nikon Z mount


Image: Tamron

Tamron has announced it will release its popular 28-75mm F2.8 Di III VXD G2 fast standard zoom for Nikon’s Z-mount.

Nikon already sells a 28-75mm F2.8 with an optical formula and calculated MTF charts that are a match for Tamron’s original, stepper-motor driven 28-75mm F2.8 Di III RXD. The newer, linear-motor-driven G2 model features improved optical performance.


Buy now:


The G2 uses a more complex 17 element / 15 group design and has a fractionally shorter minimum focus distance (18cm/7.1″ vs 19cm/7.5″) to deliver very slightly increased maximum magnification. The G2 is also a fraction lighter than the Nikon-branded 28-75mm, weighing 550g (19.4oz), rather than 565g (19.9oz). On the E-mount versions, Tamron claimed the VXD linear motor design was twice as fast as the RXD version.

The focal length range makes the 28-75mm a wide to short-telephoto lens for Nikon’s full-frame Z-mount cameras but could, in principle, be used as a 42-113mm equivalent on DX APS-C bodies, if you wished.

The announcement adds a more affordable option for Nikon’s Z-mount users, but the hope has to be that, letting Tamron compete against its own-brand lenses, might also indicate some relaxation of Nikon’s restrictions around the mount. As the footnotes make clear, this lens is “developed, manufactured and sold under the license agreement with Nikon Corporation.”

The Tamron 28-75mm F2.8 Di III VXD will be available from April 18th at an MSRP of $999. This is $100 more than the E-mount version and a match for the current price of the Nikkor Z 28-75mm F2.8. It’s $200 below Nikon’s launch price for the Nikkor version.

TAMRON announces the launch of fast-aperture standard zoom lens for “Nikon Z mount system”

28-75mm F/2.8 Di III VXD G2 (Model A063) for Nikon Z mount

March 27, 2024, 11pm ET / 8PM PT, Commack, NY – Tamron announces the launch of the 28-75mm F/2.8 Di III VXD G2 (Model A063), a fast-aperture standard zoom lens, for Nikon Z mount full-frame mirrorless cameras1. The lens will be available April 18, 2024, at $999 USD / $1399 CAD.

The 28-75mm F2.8 G2 is compact and easy to use yet has excellent optical performance and is compatible with the latest digital cameras with increasingly high pixel resolution. The AF drive uses a linear motor focus mechanism VXD (Voice-coil eXtreme-torque Drive) that is fast, highly accurate and quiet. The lens also excels at close-up shooting, achieving an MOD (Minimum Object Distance) of 7.1” (0.18m) at the wide end and a maximum magnification ratio of 1:2.7. Additionally, the lens design takes operability into consideration by including a coating with excellent scratch resistance on the barrel of the lens and a rubber focusing ring for a comfortable, secure grip among other features.

TAMRON pioneered the category of compact fast-aperture standard zoom lenses for mirrorless models. Now the 28-75mm F2.8 G2 will be available for Nikon Z mount as the ideal everyday lens for Nikon full-frame mirrorless camera users.

Product highlights

1. Best image quality in the standard zoom lens class

The new zoom leverages the latest design expertise and comprises an optical construction with 17 elements in 15 groups. Two optimally arranged LD (Low Dispersion) and GM (Glass Molded Aspherical) lens elements control optical aberrations to the highest degree. The lens provides high-resolution performance from edge-to-edge and corner-to-corner over the entire zoom range, even at wide open aperture. In addition, the soft, beautiful, round bokeh that can be achieved with a fast-aperture lens adds a distinctive dimension, especially to portraits. The overall compact size and high performance can be used advantageously with top-class, ultra-high-resolution mirrorless cameras.

2. Fast, quiet VXD linear motor for high-speed and high precision autofocus

The AF drive system employs TAMRON’s VXD linear motor focus mechanism. The high-speed, high-precision AF is exceedingly responsive and provides dependable and accurate focusing performance from MOD to infinity, despite the fast F2.8 aperture. The lens delivers excellent focus tracking of moving objects, so you are always ready for fast action. Additionally, the focus motor is quiet, so it’s ideal for shooting both still images and video in situations that demand low noise.

3. Lightweight and compact

The 28-75mm F2.8 G2 is a fast-aperture standard zoom lens with a remarkably compact and lightweight design, just 4.7” (119.8mm) long. The maximum diameter is 75.8mm and it weighs only 19.4 oz. (550g). Filter size is 67mm. With a size that’s easy to carry and a light weight that’s well-suited for handheld shooting for extended periods, the 28-75mm F2.8 G2 will surely become your favorite zoom for travel, street shooting, everyday carry, and spontaneous photo opportunities.

4. MOD of 7.1” (0.18m) at the wide end and a maximum magnification ratio of 1:2.7 for creative close-ups

The 28-75mm F2.8 G2 features an MOD of 7.1” (0.18m) at the wide end. The working distance shrinks to around 1.7” (4.4cm) when used at MOD. Because the maximum magnification ratio is 1:2.7, you can get close to your subject for wide macro photography, enabling powerful visual impact with the subject positioned large in the frame while keeping a wide view of the background.

5. TAMRON Lens Utility™ expands the possibilities of still photography and video shooting

The 28-75mm F2.8 G2 is compatible with the dedicated TAMRON Lens Utility software developed in-house by TAMRON that empowers users to easily update the lens to the latest firmware without going through the camera2 and includes functions to support focusing operations and other actions when shooting still images or video. By utilizing a wide range of functions3, users can expand the breadth of expression in still images and video. For example, A-B Focus allows users to limit focusing to two pre-selected focus points, shifting focus from one subject to the other with just a click of the Focus Set Button. Users can also choose between Linear and Non-Linear, which affects how the focus shifts during manual focusing.

6. Enhanced overall lens design for user-friendly operation

Every individual part of the lens has been carefully scrutinized, right down to the fine details, resulting in an enhanced design that optimizes both operability and ergonomics. The surface of the lens exterior is glossy black. Improved abrasion resistance makes the lens barrel harder to scratch and resists fingerprints. Additionally, the grip performance has been improved. The smoothly curved, elegant surface of the brand ring creates a dignified appearance with a design that signifies functional beauty and high quality.

7. Moisture-Resistant Construction and Fluorine Coating provide extra protection

1. The lens for Sony E-mount previously launched on October 28, 2021.

2. To connect your PC and lens, use the TAMRON Connection Cable (USB Type-A to Type-C/ Model CC-150, or USB Type-C to Type-C/ Model CC-350) sold separately. To connect your smartphone and lens, use the TAMRON Connection Cable (USB Type-C to Type-C/ Model CC-350) sold separately. Lens firmware updates are not supported with the Mobile version. Performing firmware updates requires the TAMRON Lens Utility for PC and a computer.

3. The ring function (Focus/Aperture) is not supported for Nikon Z mount.

Sony announces major firmware upgrades for a1, a9 III, a7S III and a7 IV

Sony announces major firmware upgrades for a1, a9 III, a7S III and a7 IV


Photo: Dan Bracaglia

Sony has announced major firmware updates for four of its current full-frame range, bringing many features and behaviors up to its latest standards and adding C2PA authenticity verification capabilities.

Sony a1 f/w v2.00

Firmware v2.00 for the Sony a1 is perhaps the most extensive, adding features that have appeared in other models in the three-and-a-bit years since it was launched, such as the lens breathing compensation function. It also adds a handful of new features and modifications of behavior, including an option to ensure the EVF remains on, regardless of the LCD position, and relay playback of images across multiple media. Among the extensive list of additions an updates are features such as Timecode Sync, previously only available in Sony’s Cinema Line cameras.

A series of FTP options, including SFTP support are also added.

The firmware doesn’t activate the C2PA function – which not only authenticates the camera and date/time but also that the photo is of a 3D subject, not a photo of a photo – but instead adds the capability to the camera. Once installed, users need to activate a separate license via the Creators’ App to use the function.

Sony a7S III f/w v3.00

Firmware v3.00 brings many of the updates seen in the a1, including Timecode Sync, breathing compensation and relay playback. It also adds the ability to close the mechanical shutter when the camera is turned off, to mitigate dust ingress, and the ability to transfer Raw files to smartphones.

In addition to the C2PA capability, firmware v3.00 includes the ability to add DCI 4K 24p shooting. Again a license needs to be downloaded to a camera running the new firmware to actually activate the function.

Sony a7 IV f/w v3.00

As one of the most recently updated cameras on this list, the a7 IV gains fewer features than the other cameras here. But in addition to C2PA capability, it adds network streaming, direct cloud upload support and an expansion of the features accessible via software development kit (SDK).

Sony a9 III f/w v2.00 [Expected April 9th]

As the newest of the cameras here, the a9 III receives fewer additions and updates than the a1 and a7S III, as in many instances they are gaining the features that the latest a9 introduced. However, in addition to details such as outputting lens names in video file metadata, the a9 III gains the promised ability to use the camera’s full shutter speed range when continuous shooting. But beyond this, the a9 III gains a small array of feature expansions and refinements being added across the four cameras, including the ability to extract stills from video capture, to take advantage of its lack of rolling shutter.

Sony Electronics Delivers Firmware Updates including C2PA Compliancy as a Next Step to Ensure Authenticity of Images

SAN DIEGO, March 27, 2024 – Today, Sony Electronics delivers the highly anticipated firmware updates for the Alpha 1 (Ver. 2.00), Alpha 7S III (Ver. 3.00), Alpha 7 IV (Ver. 3.00), and after April 2024, the Alpha 9 III (Ver.2.00). The update contains some of Sony’s most impactful technology, including Camera Authenticity Solution, the proprietary in-camera digital signature and C2PA (Coalition for Content Provenance and Authenticity) format support1. Together, these tools will make it possible for news agencies to ensure the authenticity of images, contributing to industry efforts to protect creators, and society from fake imagery.

Additionally, the firmware updates include many requested features to improve everyday use. The update evolves shooting functions and post-shooting workflow and brings advanced movie features like breathing compensation. It also includes new remote-control capabilities, new features for professional applications, and expanded access to cloud services applications.

“There is nothing more core to our mission than listening to the voices of the photographers, videographers, and filmmakers who shoot with Sony Alpha cameras. We know this community has been asking for these updates, and we’re happy to deliver. Each of these updates are designed to promote ease of use for our creators and allow them to maximize the strengths of their cameras,” says Yang Cheng, Vice President, Imaging Solutions, Sony Electronics Inc. “We’re especially pleased to deliver C2PA compliancy with this update. This compliancy paired with our unique digital signature technology, allows us to offer the most secure and comprehensive solution to protect professional photographers, news agencies, and society from manipulated imagery.”

Camera Authenticity Solution

Last year, Sony announced its commitment to developing technology in its cameras to aid in the fight against manipulated imagery and AI-generated fakes. The severity of this issue is only increasing and it’s a complex problem that requires the focus and attention of our entire industry.

One critical part of the solution is making more Sony cameras C2PA compliant. C2PA is a Joint Development Foundation project, where Sony is a steering committee member. C2PA aims to develop an end-to-end open technical standard to provide publishers, creators and consumers with opt-in, flexible ways to understand the authenticity, and provenance of different types of media. The C2PA is a standards-setting body that will develop technical specifications on content provenance and authentication by certifying the source and history of media content. With this firmware update, the authenticity information embedded on images from Alpha 1, Alpha 9 III, Alpha 7S III, and Alpha 7 IV can be maintained from capture through publication. This provides professional photographers with the ability to preserve their digital signature from the camera, while tracking the editing history throughout revisions.

Another critical component of the solution is Sony’s in-camera digital signature technology2 that signs images in real-time. This new feature certifies the authenticity of an image at the point of capture and creates a ‘digital birth certificate’ that is retained throughout revisions. The signature contains metadata including 3D-depth information captured through the proprietary technology in the image sensor developed by Sony. This depth information can show if the image captured was of an actual 3D object, vs a photograph of an image or video, providing an extra level of protection and even more assurance of the content’s authenticity, and making Sony’s solution especially unique for photojournalists and news agencies.

Sony’s solution also helps protect the authenticity of content by including an Image Validation Site, which verifies the image even after edits have been made by C2PA-compliant editing software. This service confirms the authenticity of the photo was taken by a specific camera and that the object of the photo is 3D. This service will initially be offered to select news media agencies, expanding to other agencies at a later date.
