The Sony a7 III, released in April 2018, continues to be a popular choice among photographers and videographers for its blend of advanced features, impressive image quality, and relatively affordable price point within the full-frame mirrorless camera market. Let’s delve into a comprehensive review of its features, pros, cons, and how it compares to other cameras in its class.
Design and Build Quality
The Sony a7 III sports a familiar and ergonomic design that is well-suited for a range of shooting scenarios. Its weather-sealed magnesium alloy body feels robust and durable, making it suitable for use in various weather conditions. The grip is comfortable, providing a secure hold during extended shooting sessions. The layout of controls is intuitive, with customizable buttons allowing users to tailor the camera’s operation to their preferences.
Image Quality
At the heart of the Sony a7 III is a 24.2-megapixel full-frame Exmor R CMOS sensor coupled with the BIONZ X image processor. This combination delivers exceptional image quality with impressive dynamic range, low noise performance, and accurate colors. The camera’s ISO range of 100-51200 (expandable to ISO 50-204800) ensures excellent performance in low-light conditions, making it a versatile tool for various photography genres.
Autofocus Performance
One of the standout features of the Sony a7 III is its advanced autofocus system, boasting 693 phase-detection autofocus points covering approximately 93% of the frame. This results in fast and accurate autofocus performance, even in challenging lighting situations. Eye AF, available in both stills and video modes, tracks subjects’ eyes with remarkable precision, making it ideal for portrait photography and capturing moving subjects.
Video Capabilities
The Sony a7 III is a capable video camera, offering 4K UHD video recording at up to 30fps with full pixel readout and no pixel binning. Additionally, it supports 1080p Full HD recording at up to 120fps for smooth slow-motion footage. The camera provides various picture profiles, including S-Log2, S-Log3, and HLG (Hybrid Log-Gamma), allowing for extensive post-processing flexibility and dynamic range expansion.
Battery Life
With its NP-FZ100 rechargeable lithium-ion battery, the Sony a7 III offers impressive battery life compared to its predecessors and competitors. On a single charge, users can expect to capture approximately 610 shots (CIPA standard) or record up to 125 minutes of continuous video recording. Additionally, the camera supports USB charging, allowing for convenient recharging on the go.

User reviews
A7iii. When I ordered this shipping took around four or five days it did get delayed, but I do not think that it’s the shippers fault. It was FedEx‘s fault when I got the camera in hand it had a shutter count of around three. It was in very, very very, very good Condition almost as if it was never used. I have been using it for about a day now and I am very satisfied with the product. The photos are very sharp and it excels at low light photography.
All-around camera except for wide and detailed images. It is the best camera I have held in my life. The only comparison would be Canon 5D and 7D so far in both a direct comparison of features, and the different noteworthy abilities each camera has. I have used it for projects, personal traveling, testing camera settings for others, etc. It has been hung on my neck in -10 F degrees to 60 F.(Note: I will add pictures once 6 months following purchase.)
Great camera.
Premature Shutter Failure :(. The camera failed at 37k actuations after two years, in the middle of a photo session. What a nightmare! At least it wasn’t a wedding! For reference, A7IIIs are rated for 200k+ images. My other camera (also an A7III) that I bought directly from Sony and it has lasted me 5+ years already. I have yet to hear from this seller, but if you’re a small business owner like I am, I would proceed with caution when buying from here!
Like New Refurbished A7 III. A7iii arrived quickly w/ good tracking communication from the seller. If I had not purchased it as refurbished I would have thought it was new. Arrived in original box w/ all paperwork and accessories. Shutter count was in low 400's vs. a ~200K lifetime, so barely used. Many great features and it does an excellent job of landscape and outdoors photos, which was my main purpose.
Best camera on the market. All I say is wow
Thes best Camera ever. very good camera and seller. Im so happy with my Sony. Thank you.
Good technology. Not completely comfortable in my hand like my Nikon
