The Zeikos 37mm High Quality 3.5X Telephoto Lens is an auxiliary lens that magnifies your existing lens by a factor of 3.5x. For example, when this auxiliary lens is attached to a 50mm lens, the lens will have an angle of view of a 175mm lens. This multicoated optical glass auxiliary lens attaches to the front of an existing lens with a 37mm filter thread. Using this "auxiliary" telephoto lens is an economical alternative to buying expensive lenses.
