This camera was replaced by the Sony α7 IV

The Sony α7 III is a full-frame mirrorless camera first released in 2018. It's the third iteration of the "base" full-frame model in Sony's popular Alpha 7 lineup, alongside the compact Sony α7C, the high-resolution Sony α7R, and the low-light-sensitive Sony α7S, offering a well-balanced feature set for a range of different kinds of photography. Though it's no longer top of its class, its excellent sensor, highly effective autofocus, respectably quick burst rate, and in-body image stabilization make it a great choice for those looking to get into full-frame photography.

Our Verdict

N/A Travel Photography

The Sony Alpha 7III is good for travel photography. While it isn't the most compact option, it's still relatively portable for a full-frame camera. Images look sharp and detailed, performing well even in low-light conditions. It's also fitted with a fairly quick and accurate autofocus system that's great for busier scenes or faster subjects. Plus, it has excellent battery life for a mirrorless model. It isn't weather-sealed, and its menu system can be a pain to navigate.

Pros
  • Superb image quality.
  • Great build quality.
  • Quick, reliable autofocus system.
  • Excellent battery life.
Cons
  • Not especially portable.
  • Menu system is difficult to navigate.
N/A Landscape Photography

The Sony α7 III is excellent for landscape photography. Images are detailed, with relatively little noise when shooting in low light. It also has fantastic dynamic range, so it preserves a wide range of shadow and highlight detail in high-contrast scenes. The camera itself feels quite sturdy, too, though it isn't weather-sealed. It isn't the most portable to take to remote shooting locations or on long hikes, but it's still relatively compact for a full-frame model.

Pros
  • Great build quality.
  • Fantastic dynamic range.
  • Good noise handling.
Cons
  • Not especially portable.
  • Menu system is difficult to navigate.
N/A Sport & Wildlife Photography

The Sony a7III is great for sports and wildlife photography. Image quality is fantastic, and it has a great autofocus system with a decent AF tracking feature to continuously keep moving subjects in focus. Its max continuous shooting speed is fairly quick, allowing you to capture quick bursts of moving subjects. That said, its photo buffer isn't the deepest, and it takes a little while to clear when you fill it up, which can slow you down at a critical moment.

Pros
  • Superb image quality.
  • Great build quality.
  • Quick, reliable autofocus system.
Cons
  • Long buffer clearing time.
  • Menu system is difficult to navigate.
N/A Raw Photo Performance

The Sony a7 III has excellent RAW image quality. Its dynamic range is fantastic, so it can capture a wide range of shadow and highlight detail. Images also look sharp and detailed thanks to its high-resolution sensor. While it doesn't have the greatest noise handling, it still does a good job of managing noise in low light.

Pros
  • Fantastic dynamic range.
  • Good noise handling.
Cons
N/A Vlogging

The Sony Alpha 7 III isn't meant for vlogging, though it's a solid video camera nonetheless. Its video quality is excellent, and it has an amazing face-tracking feature to ensure you or your subject stays in focus. That said, its screen only tilts and doesn't fully articulate, so you can't see yourself when the camera is pointed at you. Its image stabilization performance is also somewhat lacking, and it's not the most portable option for on-the-go vlogs.

Pros
  • Great build quality.
  • Great video quality with low visual noise, even in dark environments.
  • Outstanding video autofocus performance.
Cons
  • Not especially portable.
  • Poor video stabilization in 4k.
  • Screen doesn't fully rotate.
N/A Studio Video

The Sony a7III is an excellent option for studio video. It has a wide array of inputs and outputs for videography accessories, records high-quality footage, and delivers excellent autofocus performance. Its battery life is also fantastic, with no overheating issues. You also get Log profiles to capture a wider range of detail. That said, it's limited to 8-bit 4:2:0 internal recording, giving you less flexibility in post compared to newer models. Its menu system is also poorly organized and hard to navigate.

Pros
  • Great video quality with low visual noise, even in dark environments.
  • Outstanding video autofocus performance.
  • Wide variety of inputs and outputs for accessories.
  • Supports Log recording.
Cons
  • Menu system is difficult to navigate.
  • Limited to 8-bit video recording.
N/A Action Video

The Sony Alpha 7III isn't designed for action video. It's too big to mount onto a helmet rig and isn't water-resistant. 4k frame rate options are also limited, though it does support 1080p recording at 120 fps, allowing you to create slow-motion videos.

Pros
  • Great build quality.
Cons
  • Not especially portable.
  • Poor video stabilization in 4k.

Differences Between Sizes And Variants

The Sony Alpha 7 III only has one color variant: 'Black'. You can see our unit's label here.

Depending on the retailer, you can buy the Sony a7III with the Sony FE 28-70mm F/3.5-5.6 OSS kits lens, in a bundle with other E-mount lenses, like the Sony FE 24-105mm f/4 G OSS lens, or without a lens at all.

If you come across a different variant, let us know in the discussions, and we'll update our review.

Compared To Other Cameras

The Sony a7III is an excellent full-frame camera that offers a ton of value for its price now that it's been superseded by the Sony α7 IV. With plenty of native and third-party lens options, an amazing-for-its-time autofocus system, and a sensor that still holds up remarkably well regarding image quality, the a7III has much to offer for those looking for a full-frame mirrorless camera. Just don't expect the latest and greatest video features or quality-of-life features like a more intuitive menu system and more robust weather-sealing.

The α7 III is much more well-rounded for photography, with a full-frame sensor, a viewfinder, in-body image stabilization, and dual SD card slots. The ZV-E10, on the other hand, is a budget vlogging camera with a more portable design and a fully articulated screen, making it the better choice for on-the-go vlogging.

Canon EOS RP

The Sony α7 III is better overall than the Canon EOS RP. Though it's a bit less portable, it feels better built and has a much longer battery life. It also has better video features and a sensor with more dynamic range, making it more well-rounded. Sony's E-mount system also gives you a wider range of lens options to choose from.

Canon EOS R50

If you're just getting started with photography or on a budget, you'll likely be better served by the Canon EOS R50. It's a great entryway camera with a portable body, good autofocus, a highly intuitive user interface, and a great APS-C sensor. The higher-end Sony α7 III is a more capable overall camera, with a full-frame sensor, more physical controls, in-body image stabilization, and dual SD card slots, as well as a more established lens ecosystem, making it a better fit for those who already know their way around a camera.

Canon EOS R

If you're looking for something more well-rounded, that's the Sony α7 III. While the Canon EOS R is a great photography camera in its own right, with advantages like weather-sealing and a higher-resolution EVF, the Sony has a better autofocus system, faster burst shooting, and a more established lens ecosystem. It's also better suited to video work, with more usable frame rate options, less rolling shutter, and dual SD card slots.

Canon EOS 5D Mark IV

The Canon EOS 5D Mark IV and the Sony α7 III are different camera types. The Canon is a DSLR, so while it's built like a tank and has a longer battery life, it also lags behind the Sony in areas like autofocus, burst speed, and video. The Sony is also significantly more portable.

Nikon Z f

If you like the look and ergonomics of a vintage-style camera, the Nikon Z f is the way to go over the Sony α7 III. It's a newer model, so it has some benefits over the older Sony camera, including a higher-resolution EVF, faster burst shooting, and more effective AF tracking. It also has better internal video recording specs, with more frame rate options and features like internal 10-bit capture and longer recording time limits. The Sony camera has a more established lens ecosystem and holds its own for RAW image quality.

Canon EOS 90D

The Canon EOS 90D and the Sony α7 III are different types of cameras. The Canon is a mid-range APS-C DSLR, whereas the Sony is a hybrid full-frame camera. The Canon is a good option for wildlife photography thanks to its high-resolution APS-C sensor and for those who prioritize battery life and ergonomics. However, the Sony camera is better overall for hybrid and video shooters, with better video capabilities, a more intuitive overall autofocus system, and better noise handling in low light.

Fujifilm X-T5

The Fujifilm X-T5 and the Sony α7 III are both great cameras but use different-sized sensors. The Fujifilm has a more old-school design, with dedicated exposure dials and a smaller hand grip. While the Sony is a bit bulkier, it has a more ergonomic hand grip. The Fujifilm is newer, so it has a few advantages in areas like burst shooting, autofocus tracking, and video features. However, the Sony is still worth considering if you need full-frame image quality.

Fujifilm X100V

The Sony α7 III and the Fujifilm X100V are very different cameras. The Sony is a full-frame interchangeable lens camera, while the Fujifilm is a compact fixed-lens camera with an APS-C sensor. The Fujifilm is better for those who want an everyday carry camera for things like street and travel photography. The Sony is better for enthusiast photographers who want full-frame image quality and the flexibility to switch out lenses.

Sony α7 IV

The Sony α7 IV replaces the Sony α7 III. It has a new, higher-resolution 33-megapixel sensor and an improved autofocus system. Physically, the α7 IV is a little bigger and includes two UHS-II SD card slots, one of which has an integrated CFexpress Type A slot and has a fully articulated touchscreen and improved menu system. The α7 III, on the other hand, has two SD card slots, but only one of them is rated for UHS-II cards and has a tilting screen and more confusing menu. While both are fantastic cameras for photography, the α7 IV supports 10-bit 4:2:2 video recording internally and can capture video at exceptionally high bit rates, making it the better option for videographers. If you're mainly interested in photography, the α7 III still offers a lot of value.

Nikon D780

The Sony α7 III and the Nikon D780 are both enthusiast-oriented full-frame cameras, but they're different camera types. The Sony is a mirrorless camera with an electronic viewfinder that lets you see changes to exposure directly through the finder, while the Nikon is a DSLR with an optical viewfinder that gives you a lag-free, unfiltered view through the lens. The Sony is lighter and more portable and has a more reliable overall autofocus system. However, the Nikon has a longer battery life and a more intuitive menu system and controls.

Sony α7 II

The Sony α7 III offers some improvements over the Sony α7 II, including a newer backside-illuminated sensor that performs a little better in low light and a much-improved autofocus system and video features like 4k recording.

Fujifilm X-T30 II

The Sony α7 III is better than the Fujifilm X-T30 II. It's a higher-end camera with a full-frame sensor that offers better build quality and ergonomics, as well as a better autofocus system and longer battery life.

Nikon Z 6II

The Nikon Z 6II and the Sony α7 III are both excellent full-frame cameras, but the Nikon has a few advantages. It has a higher-resolution viewfinder, a better menu system, and faster burst shooting, along with a more effective IBIS system and weather-sealing. However, its battery life is notably shorter than the Sony's.

Panasonic LUMIX GH5s

The Panasonic LUMIX GH5s and the Sony α7 III have different strengths and weaknesses. The Panasonic is a better option for videography and filmmaking since it can record 10-bit video internally, offers more 4k frame rate options, and has higher bit rates. While the Sony is no slouch in the video department, it's aimed more at photographers. Its full-frame sensor gives you a wider dynamic range and better low-light performance. It also has a much more reliable autofocus system.

Battery life is fantastic. It's among the best mirrorless cameras we've tested for battery life. While the 610-shot CIPA rating should be taken with a grain of salt for real-world usage, it gives you a good idea of how the camera compares to its peers. On that front, it has a better rating than most mirrorless models. It still falls far short of DSLR battery life, but you'll get a lot of juice out of this camera, depending on how you use it.

Video battery life is also superb. On a full charge, you can expect over two hours of continuous 4k recording with little to no overheating interruptions.

The Sony a7III can shoot at a respectable 10 fps max burst rate, which is sufficient for sequential burst photos of most fast-moving subjects. However, its buffer depth is somewhat limited, especially compared to newer cameras with more processing power, including the Sony α7 IV. It also takes a fair amount of time to clear the photo buffer once full, which can slow you down or cause you to miss a critical moment.

The Sony a7 III has a solid tracking feature, especially for its time. It supports face and eye detection with Sony's 'Real Time Eye AF', which seamlessly integrates face and eye tracking and makes it very easy to pull off "set it and forget it" autofocusing. It isn't quite as sophisticated as newer Sony models, so it'll still miss focus sometimes, especially with faster or more erratic subjects. But all in all, it's fairly reliable.

While the Sony a7 III has built-in sensor-shift stabilization, it isn't the most effective. On Sony cameras, 'SteadyShot' works in tandem with 'OSS' or 'Optical SteadyShot' on Sony lenses. With a Sony optically stabilized lens, you can get clear shots at fairly slow shutter speeds shooting handheld, but stabilization depends on your lens, focal length, and even how steady your hands are, so your mileage will vary.

For one, it's limited to 8-bit capture, giving you less leeway to color-grade Log footage. It also has a 30-minute cap on recording. On the upside, the camera doesn't overheat easily.

The autofocus is excellent when recording 4k video. While Eye AF is only available in photo mode, the camera still has face detection and tracking in video, and it's very reliable with moving subjects, rarely losing its target even as they move around. The general subject tracking, where you manually select a target, is also very reliable.

Overall, the video quality is great. 4k video is clear and detailed, and the camera does a good job in low light.

Rolling shutter performance is okay. There's some noticeable distortion when panning the camera quickly, but it isn't quite as bad as some of the crop-sensor Sonys, like the Sony α6400.

As with 4k, FHD internal recording is good but nothing that'll blow you away if you're serious about video. It has a 30-minute cap on recording and is limited to 8-bit 4:2:0 recording, giving you less leeway for editing and color-grading.

Autofocus performance is just as amazing in 1080p as it is in 4k. The camera has little trouble keeping fast-moving subjects in focus.

1080p video quality is fantastic relative to other Full HD cameras. Videos look remarkably detailed, and there's very little noise in low light.

Rolling shutter is a lot less noticeable in 1080p. There's still some slanting with faster pans and camera movements, but it isn't too distracting.

The camera has two SD card slots, which is great if you like to keep a running backup or separate JPEG and RAW files. The slots are well-placed on the side of the camera, allowing you to easily switch out cards when the camera is mounted on a tripod.

The inputs are all located on the left side of the camera. There's a USB-C port for charging and file transfer, a Micro HDMI port to connect an external display, a headphone jack, and a microphone jack. The input cover flaps feel somewhat flimsy, especially compared to the sturdier, weather-sealed covers on the Sony α7C.
