The Nikon 500mm f/8 Reflex-NIKKOR is optically superb, however it is nearly impossible to make sharp images with it. It is best used as a telescope with the Nikon Lens Scope Converter. It has ten times the magnification of a standard lens, but doesn’t weigh much more than a standard lens.
Can a 500mm lens be used on a full frame camera?
The Bower 500mm lens can be used on full-frame and crop sensors bodies but does require a T-Mount adapter to work with the most popular camera makes.
