What Buyers Say
Sony a7S a7S III Black 2020
78 out of 100 high confidence 68 reviews
The Sony A7S III earns high marks from most users for its exceptional low-light performance, reliable autofocus, and excellent 4K video quality at up to 120fps. Many videographers and hybrid shooters praise its ergonomics, improved menu system, and heat management for typical use. However, a minority report serious overheating during extended recording, especially in warm environments, and some criticize the steep price, the lack of RAW video recording, and the need for costly high-speed memory cards. The 12MP sensor is loved for low-light stills but limits cropping ability for photography-centric users.
