What Buyers Say
Sony FE 400-800mm f/6.3-8 G OSS 400mm
The Sony 400-800mm lens is praised for its sharpness and fast autofocus, often outperforming the 200-600mm. However, it is heavy, front-heavy, and requires fast shutter speeds and good light due to the F8 aperture. A significant concern is a reported crack in the fluorine coating not covered by warranty, leading to frustration.

- Fast autofocus
- Outperforms 200-600mm
- Internal focusing
- Great for wildlife photography
Cons
- Heavy and front-heavy
- F8 aperture limits low-light use
- Requires fast shutter speeds
