DESCRIPTION

This Phoenix 500mm f/6.3 Mirror Manual Focus Lens is a ultra-telephoto lens that is incredibly compact and lightweight for its focal length. This is achieved by using an advanced reflex design. The drawback to this is that only one fixed aperture is possible, and only in manual focus and manual exposure modes. It has a fixed aperture of f/6.3. The lens is adaptable to fit almost any camera lens mount using a simple T-mount adapter.
