What Buyers Say
Canon EOS R5 EOS R5 Mark II
The Canon EOS R5 Mark II is widely praised for its exceptional autofocus, especially for sports and wildlife, with many users noting a significant upgrade from the original R5. However, several reviewers report overheating issues during extended use, particularly in warm conditions, and some express disappointment with high ISO noise and occasional freezing or autofocus failures. The camera's pre-capture and eye-tracking features are game-changers for action photography, but the need for new LP-E6P batteries to unlock full functionality is a common frustration.

- Excellent for sports and wildlife photography
- Pre-capture feature for action shots
- Eye-tracking autofocus works well
- Improved viewfinder with no blackout
Cons
- Overheating during extended use

Sony a7S a7S III Black 2020
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.

- Excellent build quality and ergonomics
Cons
- Serious overheating during extended recordings
