It is compatible with full frame cameras and when used on cameras with an APS-C format sensor its 35mm focal length equivalence is 75mm. - The optical design of the lens consists of 9 elements in 6 groups including one hybrid aspherical element and one aspherical element to reduce chromatic aberrations. Also, lens elements are coated with an Ultra Multi-Coating to improve light transmission and minimize flare and ghosting. Eight diaphragm blades create a circular aperture for more attractive out-of-focus highlights. - As a manual focus and manual aperture lens, it provides a rubberized focus ring and clear aperture, distance and depth of field markings.
