Fujinon Cine Lenses are used to shoot movies, commercials, and television dramas all over the world. These lenses have world class performace and quality ingrained in their DNA. Now, with the debut of the MK lens series, that heritage finds a new form. Fujifilm has developed a new pair of cinema lenses to resolve the less-than-satisfactory aspects of DSLR lenses when used for cine applications. These new lenses produce the high performance and high quality images demanded by newly developing production markets such as movie distribution services, independent film production, and wedding videos.

Continuing the legacy of superior optical performance of "Made in Japan" Fujinon Lenses

MK lenses feature outstanding optical performance and low distortion from the center to the corners across the entire zoom range. Colour is standardised in line with all of the Fujinon HK, ZK, and XK series, simplfying the calibration of the colour grading when you use multiple lenses together.

T2.9 speed across the entire zoom range

MK lenses feature a consistent T2.9 speed throughout the 18 to 55mm and 50 to 135mm focal lengths. This allows you to shoot with shallow depths of field with a beautiful bokeh effect. The constant T-stop also contributes to reduced effort readjusting the lighting and consequently shorter overall shooting times.

Suppress focus shifts while zooming

With a conventional DSLR lens, the focal point shifts while zooming. This means you have to refocus the lens each time you change the angle of view. MK lenses suppress focus shifts by driving the front focus group and the zoom group independently. Since MK lenses suppress optically and mechanically, it also eliminates the time lags you get with electronic controls

Compact, lightweight body thanks to Super 35mm sensor compatibility and dedicated E-mount design

Both the MK18-55mm and MK50-135mm achieve a compact, lightweight body thanks to Super 35mm sensor compatibility and dedicated E-mount design. This portability is ideal for solo operation and run-and-gun shooting, where mobility is crucial

Covering the standard focal lengths for cinema producation

The focal lengths of MK18-55mm and MK50-135mm overlap between 50 and 55mm. The two MK lenses together fully cover the standard 18 to 135mm focal lengths used in cinema production

Suppress optical axis shifts while zooming

In a conventional DSLR lens, optical axis shifts occur while zooming, causing the lens to skew off center from the subject. MK Lenses suppress such skewing by adopting assembly technologies proven in Fujinon Cine Lenses. This lets you shoot a composition just the way you intended.

Suppress lens breathing

When you are focusing with a conventional DSLR lens, you may notice an unnatural change in the angle of view - making look as if you are zooming. This effect, called lens breathing is suppressed thanks to MK lenses' front inner focus system. This allows you smooth and confortable focusing of dramatically important scenes
