Close focusing performance

Considering its focal length range, the 100-500mm offers good close focusing performance, with a minimum focus distance of 0.9m at the 100mm end of the zoom, and 1.2m at 500mm. This should make it practical for conventional short-tele portraiture. The maximum magnification ratio of 0.33X is achieved at 500mm (full extension at 500mm shown in this image).

Autofocus is handled by dual Nano USM motors that can work independently of one another for fast and silent AF.
