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 zoom group independently. Since MK Lenses suppress optically and mechanically, it also eliminates the time lags you get with electric controls.
Suppress lens breathing:
When you are focusing with a conventional DSLR lens, you may notice an unnatural change in the angle of view - making it 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 comfortable focusing of dramatically important scenes.
Suppress optical axis shifts while zooming:
In a conventional DSLR lens, optical axis shifts occur while zooming, causing the lens to skew off centre 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.
200 degree focus rotation angle:
MK Lenses feature a 200 degree focus rotation angle - more than double that of a typical DSLR lens. This allows you to focus on images with shallow depths of field, which requires high accuracy.
0.8M standardized gear pitch:
Each of the three operating rings (focus, zoom, and iris) features an identical 0.8M gear pitch - the same as on all FUJINON Cine Lenses. This allows you to use follow-focus and other standard cine accessories.
Fully manual operation with three mechanical lens rings:
MK Lenses are equipped with three independently operated mechanical lens rings for focus, zoom, and iris. Because you can adjust the zoom, focus, and iris via fully manual mechanisms, you can operate the camera intuitively without the time lags you get with electric controls.
The iris ring features a seamless mechanism that gives you greater precision when adjusting exposure. It operates without the vibrations and noise that you get with a clicking mechanism.
Continuing the legacy of superior optical performance of "Made in Japan" FUJINON Cine Lenses
MK Lenses feature outstanding optical performance and low distortion - from the centre to the corners across the entire zoom range. Colour is standardized in line with all of the FUJINON HK, ZK, and XK series, simplifying the calibration of colour grading when you use multiple lenses together.
Compact, lightweight body:
A compact, lightweight body is due 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.
T2.9 speed across the entire zoom range:
Features a consistent T2.9 speed throughout the 18-55mm focal length. 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.
Covering the standard focal lengths for cinema production:
The focal lengths of the MK18-55mm and MK50-135mm (Sold Separately) overlap between 50 and 55mm. The two MK Lenses together fully cover the standard 18-135mm focal lengths uses in cinema production.
Front diameter: 85mm:
MK Lenses feature a front diameter of 85mm, ensuring compatibility with standard matte boxes:
Filter diameter: 82mm:
The filter diameter of MK Lenses is standardized at 82mm, making if easy to share filters between models.
Gear rings are located at the same position:
The gear rings for focus, zoom, and iris are located at the same position on two MK Lenses, so there's no need to readjust the postion of accessories.
MK Lenses feature a macro function that lets you close focus from 0.38 m with the MK18-55mm and from 0.85 m with the MK50-135mm (Sold Separately) at the wide end.
Flange focal distance adjustment function:
MK Lenses feature a flange focal distance adjustment mechanism, which lets you adjust the distance for individual cameras.
Bundled zoom lever:
A zoom lever is included to improve zoom ring operability.
Bundles support foot:
A bundled support foot provides stability to reduce blurring due to the weight of the lens.
Bundled lens hood:
A dedicated lens hood to suppress flare and ghosting further expands the possibilities for visual representation.
