Fujifilm has unveiled the MK Cinema Lens' series, which boast advanced optical performance, ultra-compact and lightweight design and excellent cost performance. The MK18-55mm T2.9 is a standard zoom lens with a focal length of 18-55mm and an aperture of T2.9.
The demand for high-performance cinema lenses has grown rapidly in recent years with the increasing opportunity to shoot films, corporate and commercial videos using cine and digital lenses. Cine lenses are the best choice to achieve a shallow depth-of-field and beautiful bokeh. However, since they are typically large, heavy and expensive, lower cost alternatives such as interchangeable lenses for digital cameras, which are generally more affordable and mobile. However, these lenses are designed primarily for shooting still images and can be prone to focus shift and optical axis shift while zooming. As a direct response to these problems and demand, Fujifilm has released the new MK18-55mm cine lens.
Advanced optical performance, packed into the compact and lightweight lens barrel
The MK lenses offer advanced edge-to-edge optical performance and low distortion. They are designed with integrated colour temperature with other Fujinon Cine lenses in the HK / ZK / XK series to simplify colour grading that is required when using a combination of multiple lenses.
They have T2.9 speed 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, thereby contributing to shortening shooting time.
The MK series is specifically designed for E-mount cameras with Super 35mm / APS-C sensor, and X Mount (for APS-C sensor) used in Fujifilm’s X Series of mirrorless digital cameras. They achieve advanced optical performance despite their compact and lightweight body by incorporating the benefits of short flange focal distance into optical design to the maximum extent. This accommodates shooting with a limited number of people.
Resolving issues associated with using interchangeable lenses for still digital cameras in movie production
The front focusing group of lens elements and the zooming group of lens elements are driven independently from one another to suppress focus shift while zooming which eliminates the need to re-focus after zooming in or out. The optical and mechanical approach means there is no time lags as seen in an electrical control system.
The use of the front inner-focusing system controls lens breathing (change of angle of view during focusing), so as to achieve smooth focusing in a impressive scene.
Manufacturing technology developed for conventional Fujinon cine lenses is applied to control optical axis shift while zooming, ensuring to achieve intended composition every time.
Comfortable operability provided through dedicated movie lenses
The focus ring features a rotation of a full 200 degrees to facilitate precise focusing even when shooting with a shallow depth-of-field where a high degree of precision is required.
The lenses feature three fully manual rings to enable independent adjustment of focus, zoom and iris. This enables intuitive operations which cannot be attained with an electrical mechanism that typically causes time lags.
All the operation rings have a gear pitch of 0.8M, the same as all other Fujinon cine lenses, which allows the use of all standard third party accessories for movie production, e.g. Follow Focus that enable accurate and smooth focusing.
The iris supports seamless adjustment that is free of clicking. This enables precise exposure adjustment while also preventing camera shake from clicking as well as the clicking noise.
Standardised design across the series for ease of operationOnly one matte box between the lenses is needed with a 85mm front diameter.Only one filter size between the lenses is needed with a filter thread of 82mm.The gears for the three rings are positioned in the same place so as to eliminate the need to re-position accessories when switching lenses.The lenses have a macro function that allows shooting close-up to broaden the range of scenes that can be covered with one lens.The lenses feature a Flange Focal Distance adjustment function to achieve optimum camera and lens matching, thereby bringing out the lenses’ full optical performance.
