The 50mm has a minimum focus distance of 1.5'. Internal focusing minimizes the effects of lens breathing, which insures a more consistent angle-of-view when adjusting focus. The lens is composed of 9 elements in 6 groups, including one aspherical element and one hybrid aspherical element to reduce aberrations. In addition, a lens multi-coating helps to improve light transmission reducing flare and ghosting. The filter thread diameter is 77mm.
