This 100mm lens produces a 24.8° angle-of-view when used with a full-frame sensor camera or a 35mm SLR. The 15 glass elements in 12 groups render sharply defined images with a minimum of distortion and chromatic aberrations, with a minimum focus distance of 1′ from the lens. A removable lens hood provides flare protection when shooting without a matte box, and the lens’s threaded front accepts 67mm filter rings.
