The Fujinon MK 50-135mm T2.9 achieves high optical performance and low distortion with T2.9 speed across the entire zoom range. With the MK 18-55mm, it covers the standard focal length range from 18 to 135mm for film production. Compatibility with Super 35mm/APS-C sensors and a dedicated E-mount design have resulted in an ultra-compact, lightweight lens weighing "less than 1 kg", and offering excellent value for money. It eliminates "focus and optical axis shift during zoom" and "lens breathing". What's more, it features three fully manual lens rings for focus, zoom and aperture, with a 0.8 M screw pitch and 200° angle of rotation for sophisticated operation.
