MK50-135 mm | T2.9 Lens in E-Mount

Newly designed Fujinon (MK50-135) MK Series, achieves high optical performance and low distortion with T2.9 speed across the entire zoom range.

The second lens from MK Series is MK18-55mm. Both of those lenses cover standard 18 to 135mm focal length for cinema production.

Super 35mm / APS-C sensor compatibility and E-mount dedicated design have led to a compact & “less than 1kg” lightweight body. What makes really attractive, is the actual cost of this lens, as it’s price tag is aimed at budget cinematographers.

Suppress lens breathing

When you are focusing with conventional DSLR lens, you may notice an unnatural change in the angle of view, making it look as if you are zooming. Thanks to front inner focus system in MK lenses, lens breathing is competently suppressed

Suppress optical axis shift while zooming

In conventional DSLR lenses, optical axis shifts occur while zooming, causing the lens to skew off centre from the subject. Such flaw is non-existent in Fujinon MK series.
