Manufacturer description #1

The 500mm f/8 lens is the equivalent of the 250mm lens used by 35mm cameras, but in fact it rivals the 300mm as a long telephoto lens. It is indispensable when taking photographs of subjects that are difficult to approach, such as action sports and wild animals. Despite its speed of f/8 and excellent performance, it is a light lens that weighs only 1.9kg.

Manufacturer description #2

The 500mm f/8 uses low dispersion glass to give superior resolution in a long telephoto design. It clearly separates subjects from the background with extreme compression effects. Applications include sports, wildlife, fashion, and telephoto landscape photography.
