The walimex 500/8.0 Tele Mirror Lens has a focal length of 500mm and a good luminosity of 1:8.0. The sturdy metal housing and high quality workmanship and mechanics ensure good reproduction quality. With a very short minimum focusing distance of only 1.7 metres, the lens enables very good magnification. The focusing is manual. The lens can be used with an automatic timer or manual exposure settings. Thanks to the easy handling, the lens is suited for beginners. If the exposure leeway of the digital camera is exceeded, you can use the enclosed grey filters to reduce the light. The image scale refers to the size relationship between the image and the object. A scale of 1:3 means that the object is 3 times as large as the picture.
