Build Quality, Ergonomics, and Handling

The Sony A7III has enhanced ergonomics and handling thanks to Sony’s newest mirrorless body design. In addition, with a broader grip size to accommodate Sony’s improved Z-type battery, the camera feels balanced while capturing shots. Despite being slightly larger than its predecessor, the A7 III remains very small compared to full-frame DSLR cameras.

Build Quality, Ergonomics, and Handling

Sony portrays the A7 III as dust and moisture-resistant, although the lack of rubber seals throughout the body and port doors may limit its capacity to handle extreme weather conditions. The camera’s control configuration is identical to that of the A7R III and a9, with minor physical variations.

Rear LCD Screen

The Sony A7III’s 3-inch type 921,600-dot touchscreen Display can be tilted to 107° and 41° downward. The LCD screen’s resolution is lower than some of its competitors, but it is still touch-sensitive and has Touch AF and Touchpad functions. However, the touchscreen implementation on Sony’s mirrorless cameras remains immature and seems less polished than its competitors.

Rear LCD Screen


The Sony A7III has several impressive connectivity options, including built-in Wifi with NFC for file transfer, a USB 3.1 Type-C terminal for faster image transfer speeds, a Micro USB 2.0 port for powering the camera, a Type-D Micro HDMI port, a 3.5mm headphone jack, and an external mic jack.

Camera Menu

Sony A7III’s menu layout is still confusing and tough to navigate. Several parameters, including video quality and custom button settings, Autofocus choices, Exposure and ISO settings, and Flash settings, are hidden behind perplexing menu tabs. There is no specific Movie settings tab in the menu and no option to customize the camera’s controls within the Settings menu. The first and second top-level menus share the same icon, whereas the rest use different icons. Sony may learn something from Canon and Nikon in this regard.


The Sony A7III has an industry-leading battery life for a mirrorless camera, with up to 710 photos under CIPA settings when using the NP-FZ100 battery. This is about twice the battery life of its predecessor, the A7 II, which used the NP-FW50 battery. The improved battery life of the Sony A7III is attributed to its usage of the new Z-type battery, which was launched with the Alpha 9. As a result, during real-world testing, users could shoot for a day on a single charge, even using features such as the EVF, rear screen, and vibration reduction.

Video/Movie Recording

The Sony A7III has exceptional video capabilities, with the 6k sensor readout enabling full-frame pixel 4K/24p video with no reduction, slow-motion filming at 1080/120fps, and decreased rolling shutter. The camera takes 6k pixel information and downsamples it to 4k, resulting in outstanding 4k films. With image profiles and the ability to capture Log footage internally, the Sony A7III provides comparable video quality to the A9 at half the price. It also has zebra warnings for exposure, focus peaking, and crisp HDMI output, making it a good choice for videography at this price.

Buffer and Autofocus Performance

The Sony a7III has advanced and clever autofocus technology inherited from the a9 camera. The camera boasts over 693 phase-detection autofocus points that cover 93% of the frame. The camera’s autofocus system is twice as quick as the a7 II and has 425 contrast-detection focus zones for low-light focus accuracy. Furthermore, the camera’s phase-detection coverage encompasses 93% of the frame, allowing it to track individuals as they approach the image’s edges.

The camera has several autofocus zones, including Wide, Zone, Center, Flexible Spot (Big, Mid, Little), Extended Flexible Spot, and Lock-On Focus. The A7 III’s autofocus is superb for static subjects, focussing swiftly and accurately even in low light. In addition, the camera can focus down to -3EV with an F2 lens, and the overall hit rate for Eye AF, which seeks out and tries to focus on a human eye in the frame, has been considerably boosted.

The A7 III’s continuous autofocus operates admirably, being both speedy and accurate thanks to its 693 phase-detection point autofocus technology. In addition, lock-On AF is offered with a Wide Zone, Center, Flexible Spot (small, medium, or enormous), or Expand Flexible Spot. The Lock-On AF tracks a subject based on its shape and color, encircling it with a shapeshifting frame that changes shape and size depending on the subject’s location.

The Sony A7III has a buffer capacity of about 177 frames for compressed RAW images and approximately 89 frames for uncompressed RAW photographs. This enables high-speed continuous photography at up to 10 frames per second, making it ideal for recording fast-moving action. The autofocus and buffer performance of the Sony a7III is good overall, with fast and accurate autofocus and high-speed continuous shooting capabilities.

Image Quality

The Sony A7 III is a compelling full-frame mirrorless camera with excellent image quality, especially at high ISOs. Its 24.2-megapixel back-illuminated full-frame imaging sensor offers a superb resolution and file size mix, with improved image quality at high ISOs and a more dynamic range than the A7 II.

Image Quality

1. Quality JPEG

Sony’s JPEG files have improved recently, with enhanced sharpening algorithms and color responsiveness. As a result, the A7 III produces exceptionally clean and detailed JPEGs at base ISO with minor sharpening artifacts. In addition, the camera’s JPEG engine can extract nearly as much detail as converted RAW files.

2. RAW Quality

The A7 III delivers superb RAW files with class-leading dynamic range and clarity. The AA filter in the A7 III is weaker than that in the Sony Alpha 9, resulting in more pixel-level detail on the A7 III. The A7III is a perfect way to get the desired color when combined with Capture One’s Raw Converter.

3. Dynamic Range

The A7 III’s dynamic range performance is outstanding and among the finest for a full-frame sensor. While shooting in uncompressed RAW, the camera notably benefits from a 14-bit readout, allowing it to record its entire dynamic range. With a one-stop gain over the A7 II and 1.3 stops over the A9, the A7 III has almost the same dynamic range as the A7R III at base ISO. From ISO 2000 to ISO 12800, the A7 III boasts a 1.5-stop gain over its predecessor.

4. ISO Performance

The A7 III performs well at low ISOs, with clean images at ISO 100, 200, 400, and 800. A small amount of noise can be seen in the shadows at ISO 800. With higher ISOs, noise increases, but image quality remains excellent. At ISO 1600, there is somewhat more noise evident, but it is minimal. At ISO 3200, more excellent luminance and chrominance noise is visible in the mid-tones.

At ISO 6400, overall noise increases again, but colors and details remain fine. At ISO 12800, there is a significant increase in overall noise, with chrominance noise appearing throughout the image. At ISO 25600, chrominance noise dramatically affects image quality, although the A7 III preserves useable image quality.

Overall, the Sony A7 III is a top-performing full-frame mirrorless camera with exceptional image quality, particularly at high ISOs, making it an excellent option for low-light shooting.
