A7S III key specs

Sony Alpha A7S III key specs

  • Overhauled design with new touch interface
  • Brand-new 12.1MP back-illuminated sensor
  • Up to 15 stops of dynamic range with S-Log

Solid design and large record buttons

The Sony A7S III is a relatively compact but solid camera. The body is comfortable to use with big telephoto lenses but still light enough to use with a wrist strap and a light prime if that's more your style.

The handgrip is the same as you get with the a7R IV and a9 II.

With a similar body construction to the A7S II, you would first think they look identical, but the difference is in the details.

Large record button for video shooting

For starters, one of the custom buttons above the grip has been swapped out for a large record button, setting the scene for this camera's strong emphasis on video shooting.

The rear plate includes all the expected controls—a dial-direction pad hybrid used primarily for menu navigation, a dedicated joystick to set the autofocus point, AF-ON, AEL, menu, and playback controls to round things out.

Interactable touch-screen

The on-screen interface includes controls, too. You can interact directly with the touch screen—Sony has finally updated its menus to work via touch. It has a full-sized HDMI port – a real boon for videographers – plus a USB-C port and micro USB port, not to mention a headphone jack and 3.5mm microphone jack.

Moreover, A7S III's bright, sharp viewfinder is a photographer's dream, with crisp clarity, excellent coverage, and ample brightness.

And whether you're shooting stills or video, the Sony A7S III handles well because it offers so many controls and top-end specs.

Sony a7s design and handling

Video-first capabilities

If you're just starting out making a video, it's unlikely you'd look at the A7S III right away.

The Sony a7S III is the only current-generation mirrorless camera with a relatively low pixel count sensor, especially appealing for 4K video and low-light photography.

When cropped to the 16:9 video ratio, the 12MP sensor captures 4K video at native quality, without any sort of binning, line skipping, or down-sampling. Autofocus is as capable as with stills (when using a native lens).

High-ISO imaging with 12MP BSI sensor

The pixel readout is quicker than the a7S II, so the camera records slower, slow motion and does a good job avoiding rolling shutter distortion. Therefore, hybrid creators with more eye for video will be well served by the a7S III.

Its 12MP BSI sensor offers cleaner high-ISO imaging and video than typical 24MP cameras. And the ability to record in 4K at up to 120fps can add slow motion to projects without dropping back to HD resolution.

Redesigned heat dissipation

Being able to shoot practically unlimited 4K/50p footage meant you never have to worry that the camera would overheat. The redesigned heat dissipation inside the body means the A7S III never struggles - which is a step-change from earlier Sony video-focused cameras.

The result is a smooth, sharp, and detailed video with great color. Rolling shutter seems to be a thing of the past too.

A7S III video capabilities

Incredible low-light performance

One of the first things you'll notice about the Sony A7S III is how well it performs in low light.

Ramping up the ISO is not a stressful experience; it's incredibly gratifying, with the camera able to handle high sensitivity mind-bogglingly well.

95 minutes of recording

When it comes to power, the new Z battery delivers what Sony claims to be a 60% improvement over the performance of the A7S II's NP-FW50 – up to 95 minutes of video capture, on paper.

It can comfortably capture 4K video for more than an hour, which is excellent compared to much competition. In addition, thanks to the inclusion of a USB-C port, the A7S III takes advantage of fast charging tech, powering up to four times quicker than via an old-school micro USB connector.

Quick autofocus and precise tracking

The a7S III focuses quickly and identifies subjects with profound understanding. It supports face and eye detection for people and pets and tracks subjects with tenacity.

Phase and contrast focus covers most of the sensor, giving you the freedom to frame subjects off-center. It's an effective camera for capturing action.

10fps for RAW, JPG and HEIF

It tracks subjects and fires off Raw, JPG, or HEIF photos at a brisk 10fps. The smaller files, sizable buffer, and support for ultra-fast memory allow for longer continuous bursts at a time.

Introducing Real-Time tracking

The Real-Time Tracking function in the autofocus system isn't brand new, but this is the first a7S model to include it. It's better at keeping up with a subject and much easier to use than the older Lock-On Tracking function. You don't need to hit extra buttons to start, stop or turn on the face and eye detection—it's seamless.

Tracking works in continuous focus (AF-C) only. If you're using the camera for the single-point focus, you'll still enjoy the same level of subject recognition, but the focus point won't follow a subject as it moves through the frame.

Price and availability

The A7S III was released in September 2020 and is now available to buy directly from Sony or major retailers for $3,499.99 / £3,800 / AU$5,999 for the body only.

While the sticking point with the A7S III is always going to be price – it's undoubtedly a big investment before you even start shooting if you want to pair it with decent glass and fast storage – the camera itself doesn't leave many itches unscratched.

Even so, when it comes to availability, due to the high demand for Sony Alpha a7S III, the availability is meager. It is now almost out of stock in US stores.

Final verdict: Who should get the Sony AS7 III?

The Sony Alpha A7S III is the most impressive video-centric consumer camera to date. Sony offers full-frame recording at staggering resolutions quality by using a suitable sensor, processing power, and heat dissipation.

The price might make you wince a bit, though. While the sensor and performance lend the camera to professional video work, it also makes it very good in low-light situations for both stills and video.

With a good lens, you can forget the tripod and shoot dimly lit handheld scenes.

However, those still photographers looking to shoot ultra-resolute images should look elsewhere. But for those invested in Sony for video work, the A7S III will be the mirrorless camera of choice for years to come.
