The lens delivers high optical performance and comfortable operability for professional video shooting. Along with MKX18-55mm T2.9, MKX50-135mm T2.9 is the first full manual cinema lens to be compatible with the X Series interchangeable camera. In the 35mm format equivalent, MKX50-135mm T2.9 covers a focal distance from 76mm to 206mm and achieves a constant T2.9 aperture across the entire zoom range, enabling a shallow depth of field as well as a beautiful bokeh effect. The lens design is optimized for shooting videos as it minimizes focus shift and optical axis shift while zooming and reduces lens breathing (the change of angle of view during focusing). The lens also features three rings to enable manual and independent operation of focus, zoom and iris (aperture), all with the gear pitch of 0.8M (module). The focus rings can rotate fully up to 200 degrees to facilitate precise focusing. These features make the lens very comfortable and convenient to operate. Advanced optical performance MKX50-135mm T2.9 uses 22 glass elements in 17 groups, with two super ED lens elements and two ED lens elements It has T2.9 aperture across the entire zoom range which facilitates the increasingly popular style of bokeh effect with shallow depth-of-field. This also eliminates the need to re-adjust lighting, contributing to shortening shooting time The MKX lens achieves advanced optical performance despite its compact and lightweight body by incorporat
