(Or rather 2560mm with optional 2x converter) The walimex pro 800/8.0DX Mirror Tele Lens has a focal distance of 800mm and a good speed of 1:8.0. The sturdy metal housing and the high-quality workmanship and mechanics ensure a good image quality. With a very short closest focusing distance of only 2 metres, the lens enables a very good magnification. Focusing takes place manually. Thanks to the easy handling, the lens is also especially suitable for beginners.
