Product Overview
MKX18-55mm T2.9


The lens delivers high optical performance and comfortable operability for professional video shooting. Along with MKX50-135mmT2.9, MKX18-55mmT2.9 is the first full manual cinema lens to be compatible with the X Series interchangeable camera. In the 35mm format equivalent, MKX18-55mmT2.9 covers a focal distance from 27mm to 84mm 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.
