MKX18-55mmT2.9 uses an optical construction comprising 22 glass elements in 17 groups, with six 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 incorporating the benefits of short flange focal distance of X Mount into optical design to the maximum extent. This accommodates shooting with a limited number of people.
The electrical contact to communicate with the X Series camera not only corrects the distortion and the color/brightness shading, but also achieves various color expressions with Film Simulation modes.
