Sonya a7 III review

Sony a7 III review 2023

When it comes to features, the Sony A7 III is far from basic. Its BSI CMOS sensor performs well in all light conditions and has a wide dynamic range. It has a 10fps shooting speed and a focusing mechanism that covers practically the entire image sensor. It also has significant video capabilities, capable of producing smooth, clear footage in 4K and slow-motion video in 1080p. It also has a few hardware advancements and features from the Sony A9, such as the 693-point phase-detection focusing system from the flagship model.

Let’s see the full Sony a7 III review 2023


The Sony A7 III features a 24MP sensor and 10fps continuous shooting, which is twice as fast as the preceding A7 II. The focusing technology from Sony’s top A9 sports camera has been included. In a single burst, it can capture up to 177 JPEGs, 89 compressed Raw files, or 40 uncompressed Raw photos. A ‘live view’ mode at 8 frames per second provides a quicker, more stable viewfinder image at 10 frames per second. A sensor-based 5-axis picture stabilization system with 5-stop shaking compensation and dual memory card slots are also included.

The battery can be charged in-camera with a USB connection or with the optional BC-QZ1 battery charger for rapid charging. The new A7 IV, on the other hand, features higher megapixels, a larger range of video codecs, and 4K HDR playback via Sony’s HLG (Hybrid Log-Gamma) profile, as well as Sony’s S-Log3 mode for extended dynamic range (up to 14EV) for post-production editing/grading.


The Sony a7 III is available as a $2,199.99 kit that includes the FE 28-70mm F3.5-5.6 lens. Even with a larger lens like the FE 100-400mm, I find it quite pleasant to hold. All Sony FE lenses, as well as the body, are dust and splash-resistant. The Sony a7 III’s dial is substantially more comfortable to use than the a7 II’s dial. When framing photographs with the EVF, the camera also allows you to adjust the focus using the LCD. 

My Menu is completely customizable, so you may add an option you frequently change to it for convenient access. PlayMemories Mobile camera apps are not compatible with the a7 III. The 3-inch LCD panel on the back supports touch input. Firmware 3.0 adds time-lapse, although it will fire photographs at predetermined intervals. It’s a step down from the a7 II’s 1,228k-dot display.

Build and handling:

The A7 III, like the other A7 models, is a full-frame camera that is surprisingly tiny. This is owing in part to its mirrorless design, but also the designers’ inventiveness. However, depending on the lenses you choose, it has a very front-heavy feel. There’s also no specific drive mode dial or AF mode/area lever, which is a pity. The Sony A7 III is the most economical choice among Sony’s third-generation A7 models, despite its deceiving appearance.

It feels substantial and heavy, with precise controls and high-quality external materials and finishes. With 35 panels divided into five categories and a user-customizable My Menu, the menu structure is somewhat intimidating. Instead, the Fn button on the back of the camera can be used to access most of the camera’s usual shooting settings.

Power and Connectivity:

The Sony a7 III uses the same Z battery as the a7R III, but it has a battery life of 710 shots per charge instead of 650. Two USB ports (one USB-C and one micro USB) are included, as well as micro HDMI, a 3.5mm microphone input, and a headphone jack. Two memory card slots accept all UHS-II formats at higher speeds, however, no Memory Stick media is supported.

Image Quality:

The a7 III features a new sensor that is similar in design to the a9’s 24MP sensor. Imatest claims that noise is less than 1.5 percent at ISO 25600 when shooting in JPG format. At ISO 51200, you can get usable, albeit soft, pictures. At ISO 102400, there’s a lot of blurs, but I can still see some detail in our test shots. The Sony a7 III features a full-frame image sensor with 24 megapixels and a quick, high-ISO lens.

Low ISO settings allow you to control highlights and shadows, resulting in an image that looks just how you want it to. Flare is a problem that has been brought up by certain reviewers. In heavily backlit subjects, strange banding can appear under certain settings. When shooting at f/2 or wider, it’s usually just noticeable. The banding is visible as a single pixel.

Performance and autofocus:

In bright light, the Sony a7 III’s autofocus system locks on in 0.05 seconds, while in very dim light, it takes 0.4 seconds. In its fastest burst mode, the camera can shoot at 10 frames per second and handle numerous JPG and Raw files at once. The time it takes for the buffer to completely clear to the memory card varies depending on the file format. Even when tracking moving targets at 10 frames per second, the Sony a7 III’s autofocus technology performs admirably. Eye AF’s operability was increased with Firmware 3.0, allowing it to work at all times.

It’s a terrific tool for portraiture because it works when focusing continuously, allowing your model to modify its stance freely. The Nikon D750 ($1,412.37 at Amazon UK) and Canon EOS 6D Mark II, the closest SLR competitors in terms of price, both peak out at 6.5fps.


Despite its entry-level status, the a7 III is packed with functionality. It can capture 4K video at 60 or 100Mbps utilizing the XAVC S 4K codec at 24 or 30 frames per second. When you reduce the resolution to 1080p, you can choose between 50 and 100Mbs at 24, 30, or 60p. At 120Mbps and 120Mbps, there is an in-camera slow-motion option.


  • Video in 4K HDR.
  • Use the joystick to focus.
  • Silent firing is an option. 
  • Touchscreen LCD that tilts. 
  • There are two SD card slots.


  • There is no in-body flash.
  • A menu system with a lot of options. 
  • The PC sync socket is not included.


The Sony a7 III is an entry-level full-frame camera with superb image quality, 10fps subject tracking, and 4K video capture that goes well beyond the fundamentals.
