What Buyers Say
Sony FE 400-800mm f/6.3-8 G OSS
72 out of 100 medium confidence 15 reviews
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.
