Lens Construction: 6 Elements in 6 Groups Computer-designed using a combination of lenticular light refraction and reflection optics--the same physics used in many professional telescopes. This 500mm Manual ultra-telephoto, multi-coated mirror lens is ideally suited for sports and wildlife photography. Highly complex, precision-made, optical instrument with a fixed aperture of f/8.0 which is faster than most other 500mm lenses. NOTE: This is a manual lens, NO Electronic Contacts, your camera will not detect the lens when mounted, that's why it shows "Lens Not Attached", please switch to MF MODE in order to use this lens correctly. Tips to use our Manual Lens: 1) Set the mode dial to Manual (M). 2) Set the Release w/o Lens option in the camera menu to Enable. 3) Set the Shutter lock option in the camera menu to Off: no lens.
