Review: Sony A7 III Full-frame Mirrorless Camera

The Sony A7 III is still one of the easiest all-round full-frame cameras to recommend, and yes, it absolutely makes sense to buy one today. It’s reliable, well-priced on the used market, and has proven itself in real-world shooting over the years. In fact, our video review was shot entirely on the A7 III, which says a lot about how capable it still is. While it’s no longer the flashiest camera in Sony’s line-up, it’s the go-to all-rounder for many.

Released in 2018, the A7 III still sits comfortably alongside newer models like the Sony A7 IV and higher-resolution options like the Sony A7R III.

This review is based on long-term use, too. Between MPB’s Senior Content Producer, Amy Moore, and Videographer, Jakub Golis, the Sony A7 III has spent over eight years shooting everything from portraits to landscapes and events. Amy alone has nearly 15,000 A7 III images in her Lightroom catalogue, and despite regularly working with newer Sony bodies, keeps coming back to the A7 III. She’ll tell us why that is.

What is the Sony A7 III like to use?

The Sony A7 III will surprise you with how practical it feels years after its release. Sure, it shows its age in places but it’s comfortable for long shooting days and not complicated to use.

Body design and ergonomics

The A7 III is still compact(ish) and comfortable enough to carry. Its deep grip means it’s a good fit for most Sony FE lenses, and its build quality is strong. 

Earlier Sony A7-series screens sometimes had delamination issues, but I’ve never had any issues with the A7 III.

Grip and handling with lenses

The A7 III is relatively compact when you compare it to more recent full-frame cameras. It’s practical, too, pairing well with almost anything in the Sony E lenses lineup. Tip: Pair it with a compact prime like the Samyang AF AF 35mm f/2.8 FE pancake lens, and it transforms into a lightweight travel or street photography set-up. Add a Sony FE 24-70mm f/2.8 GM or a more modern (and more expensive) Sony FE 24-70mm f/2.8 GM II, and you’ll be well equipped for professional event shoots. 

Button layout and joystick control

The A7 III is much easier to operate than earlier models. Sony made it easy to navigate focus points; there’s a rear joystick for quick selection, and the rear screen is touch-enabled, so you can intuitively move your point of focus.

Viewfinder and screen

The screen tilts rather than fully articulates, which isn’t ideal for filming yourself, but it works well for street photography or shooting from low angles. It’s quick, discreet and doesn’t draw much attention. Professional photographer Douglas Jubic tells us how easy it is to shoot on the street in our Sony A7 III for Cityscape Photography review. Our Guide to Street Photography will give you plenty of tips for taking your camera roadside, too.

While the electronic viewfinder (EVF) isn’t anything to get excited about, I’ve never had issues using it for paid work. One thing that does still catch me out, though, is the sensitivity of the eye sensor. It’s positioned just above the screen, and on bright days, it can switch to the EVF when you don’t expect it. Annoying.

Ease of use

When it was released, battery life was one of the Sony A7 III’s biggest upgrades over earlier Sony A7 models. The addition of the NP-FZ100 battery meant you could shoot weddings, events or long travel days with three or four batteries in your bag, without panicking.

The Sony A7R III, released in 2017, introduced dual card slots to Sony’s full-frame mirrorless line-up, with the Sony A7 III following suit the following year. This might make you shrug now, but at the time, it was a big deal for working photographers. Corrupted card? No longer a problem on professional shoots.

If you regularly jump between stills and video, the custom modes make the camera much easier to work with. Both photo and video settings can carry across when switching modes manually.

Eye autofocus and tracking

I’d deem the A7 III’s autofocus to be ideal for everyday shooting. You can take it to a car racetrack (like I did), and be confident you’ll lock onto your subjects.

Low-light autofocus performance is reliable, too. The autofocus system can work down to around -3 EV, so it can get surprisingly dark before the camera starts to have issues.

Note that autofocus performance is strongest for stills photography. In video, it’s not quite as sticky as the Eye AF performance you get when shooting stills.

Continuous shooting

The A7 III’s 10 frames per second (fps) are still more than enough for most types of shoots. The A7 III shoots 14-bit RAW, even at that speed. You can shoot bursts without it locking up, and use the full 10 fp in Silent Shooting mode. If you’re out shooting wildlife or weddings, this’ll be your secret weapon. You’ll find some other hands-on tips and tricks in our wildlife photography guide.

Stabilization (IBIS performance)

You can rely on in-body image stabilization when shooting handheld. One for the hybrid heads, though: I wouldn’t rely on it instead of a gimbal if I wanted smooth, “deliberate” video movement.

Sony A7 III image quality

Rest assured, the Sony A7 III can produce files you can confidently deliver to clients, thanks to its resolution, low-light performance and dynamic range.

Real-world use

One of the A7 III’s biggest strengths is consistency, as it feels at home across almost any type of photography. It produces clean, detailed files and works just as well for portraits and weddings as it does for travel and street shooting.

We go into why the camera’s such a great travel companion in our Sony A7 III for Travel Photography review.

Low-light performance and noise handling

If you spend a lot of time shooting in low-light conditions, the A7 III will cover you. Its back-illuminated full-frame sensor handles higher ISOs well, so when you’re shooting indoor events or evening street photography, there’s no sweat. If the sun’s not showing its face on an outdoor shoot day, you’ll still be fine if you ramp up the ISO and use a fast lens like the 50mm f/1.8. Native ISO runs from 100 to 51,200, and usable results at ISO 6,400 or even 10,000 aren’t difficult to achieve. You won’t want to push it too much further than that unless you want a very soft look.

Resolution and detail

At 24.2 megapixels, the A7 III gives you detailed files that are easier to store, transfer and edit day-to-day. There’s enough resolution for commercial work, large prints and cropping when it’s needed. You also don’t have to worry about enormous file sizes you get from higher-resolution bodies like the Sony A7R IV, for example. If you shoot a lot, that’ll matter. 

Dynamic range

With up to 15 stops of dynamic range, there’s enough room to recover detail in post, so if you’ve encountered a tricky lighting situation, say, out shooting landscapes, you can still have some fun with your edits. RAW files hold onto highlights well, and you can lift shadows without ruining your shots.

Colour and RAW flexibility

Colour is noticeably better than on earlier A7-series bodies (some may remember wrestling with magenta or green casts on the Sony A7 II). JPEGs straight out of the camera are usable with a bit of tweaking, and you’ll always have the “Picture Profile” settings in your back pocket if you need film-like simulations.

Is the Sony A7 III good for video?

The truth is, the A7 III is still good for casual and professional hybrid video, but it isn’t the best choice if video is your priority. There are recording limitations, and the camera’s age can hold you back a bit on the color grading side.

4K performance

You can shoot full-frame 4K with 6K oversampling, so footage still looks detailed and sharp.

You can also record in S-Log2, S-Log3 or Hybrid Log Gamma and capture slow motion at 120 frames per second in Full HD. Again, the in-body image stabilization (IBIS) also does a good job of keeping handheld footage steady.

Autofocus is reliable too, although you don’t get Eye AF in video. Instead, the A7 III uses a more general face-detection method that still works just fine.

Limitations

The biggest limitation today is that the A7 III records in 8-bit rather than 10-bit, and you can’t get around it with an external recorder either. That means less flexibility when color grading, but rewards getting your look as close as possible in-camera rather than relying on heavy edits later.

The A7 III also has an approximate 29-minute recording limit for internal video recording. For shorter interviews, podcasts or hybrid content, that’s fine, but it’s less ideal for long-form events or conferences. Some people work around this with external HDMI recorders or unofficial methods discussed online.

Connectivity and usability

Connectivity-wise, you’ve got everything you’d expect here: mic and headphone ports, HDMI out and USB charging, so it fits into most setups without issue. If you want to transfer your photos (or even control the camera from your phone), there’s Wi-Fi and Bluetooth. 

Because the A7 III is an older body, it doesn’t work with Sony’s newer Creators’ App. Instead, you’ll need to use the older Imaging Edge software for cloud transfers and remote connectivity, which generally works better on desktop than mobile.

Where the Sony A7 III fits in the A7 series

The Sony A7 III sits in the sweet spot of the A7 lineup, and for many photographers, it’s where Sony got the balance of performance, battery life, autofocus and price just right. It’s the Goldilocks option in the range. 

Across the series, every camera uses a full-frame sensor, supports Sony FE Fit lenses and offers a minimum ISO of 100 with a maximum mechanical shutter speed of 1/8000. They all use phase-detection autofocus, too, although each generation has become faster and more advanced over time.

The biggest differences between the models come down to stabilization, autofocus performance, battery life, video capabilities and subject recognition. 

Over the years, Sony has added features such as IBIS, backside-illuminated (BSI) sensor technology and smarter autofocus systems, with the Sony A7 V introducing a redesigned processor and AI-assisted subject recognition.

Sony A7 III alternatives

If the A7 III doesn’t quite fit what you need, Sony’s full-frame line-up splits into a few clear directions. The standard A7 series focuses on hybrid shooting, the A7R series prioritises high resolution for detail-heavy work and the A7S series is built around video and low-light performance, with the “S” standing for sensitivity.

All four cameras below use a full-frame BSI sensor, phase-detection autofocus, Sony’s NP-FZ100 battery and can shoot at up to 10 fps or higher. The biggest differences come down to resolution, video features, autofocus intelligence and how specialized each camera feels in day-to-day use.

Sony A7C for compact shooting

While it isn’t technically part of the main A7 line-up, the Sony A7C shares much of the A7 III’s performance in a smaller, rangefinder-style body with a corner-mounted viewfinder.

You get very similar image quality and autofocus performance, but in a more compact design with a single card slot. Good for travel photography, street photography and everyday carry setups.

Sony A7R III for more resolution

Regularly shoot more detailed shots for big billboards or similar? The Sony A7R III makes more sense if resolution is your priority, thanks to its sharp-looking files. 

Its 42.4 megapixel sensor gives you far more detail and cropping flexibility than the A7 III, which is what you want for commercial photography and studio work. The trade-off is larger files and a slightly heavier editing workflow, but if maximum detail matters to you, it’s worth it.

Sony A7S III for video and low light

If video is your priority, the Sony A7S III makes more sense than the A7 III. The A7S range is known for its ridiculously good video and low-light performance, which is why wedding videographers and documentary shooters lean on them so heavily. The Sony A7S III is a video production master, with 4K 120p recording, improved codecs and better heat management for longer shoots.
