HIGHLIGHTS
The a7 III is the camera that made full-frame mirrorless feel normal, and it's still sold new in 2026. Its 24.2-megapixel back-illuminated sensor, 693-point phase-detect autofocus and 5-axis in-body stabilization (rated at 5 stops) cover almost everything a hobbyist or event shooter needs. The NP-FZ100 battery is rated for about 610 shots through the viewfinder and 710 on the screen, so one charge lasts a full day.
The catch is age. Next to the a7 IV and a7 V, it gives up resolution, newer subject-detection AF and modern video. Bursts top out at 10 fps, video at 4K/30p in 8-bit, and the 921,600-dot rear screen only tilts. For stills-first buyers, that may matter less.
Our gallery comes from six photographers using six different lenses, from a Tamron 28-200 to the FE 16-35mm GM: a New Zealand robin at ISO 12800, a Hualien train at 1/30 s, Tokyo storefronts and a black-and-white study of Norwegian trees. Digital Camera World still recommends it eight years on.
The story
Sony announced the α7 III (ILCE-7M3) on February 26, 2018 as the "basic" model of its full-frame line, at $2,000 body-only or $2,200 with the FE 28-70mm kit lens (Sony release).
It has outlived two successors: the 33MP a7 IV arrived in 2021 and the a7 V in December 2025, but Sony still sells the a7 III.
Sony still sells the a7 III new.

Verdict
Buy it if you want full-frame stills with IBIS. The sensor, stabilization and battery life still hold up.
Step up to the a7 IV or a7 V if video, higher resolution or modern subject-detection AF matter to you.
