The Dawn of a New Era
Fujinon Cine Lenses are used to shoot movies, commercials, and television dramas all over the world. These lenses have world-class performance 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.
The Fujinon MK-R zooms are a modification to the original Fujinon MK lenses performed by Duclos Lenses to equip them with a fixed Canon RF mount. The Fujinon MK line sets itself apart from the pack with an ultra lightweight design combined with Fujinon's cinema lens pedigree. Ideally matching Fujinon's established Cabrio XK line, the MK lenses are an excellent choice for mirrorless camera systems. The integratd Macro functionality and adjustable back focus provide features normally reserved for high-end motion picture zoom lenses. The MK-R zooms are an ideal pairing with the new RED KOMODO 6K and Canon C70 camera thanks to their native RF mount, versatility, and reliability. (minor vignetting at small apertures between 18mm and 20mm).
Front diameter: 85mmMK Lenses feature a front diameter of 85mm, ensuring compatibility with standard matte boxes.
Filter diameter: 82mmThe filter diameter of MK Lenses is standardized at 82mm, making it easy to share filters between models.
Gear rings are located at the same positionThe 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 position of accessories.
Macro functionMK Lenses feature a macro function that lets you close focus from 0.38m with the MK18-55mm and from 0.85m with the 50-135mm at the wide end.
Flange focal distance adjustment functionMK Lenses feature a flange focal distance adjustment mechanism, which lets you adjust the distance for individual cameras.
Bundled zoom leverA zoom lever is included to improve zoom ring operability.
Bundled support footA bundled support foot provides stability to reduce blurring due to the weight of the lens.
Bundled lens hoodA dedicated lens hood to suppress flare and ghosting further expands the possibilities for visual representation.
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 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 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.
Sophisticated Operability that brings out its full potential as a cinema lens
200° focus rotation angleMK Lenses feature a 200° 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.
Fully manual operation with three mechanical lens ringsMK 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.
0.8M standardized gear pitchEach of the three operating rings (focus, zoom, 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.
Seamless irisThe 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 disortion - from the center 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 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.
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.
Covering the standard focal lengths for cinema production
The focal lengths of the 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.
