Fujifilm Launches New MK Series of Lenses (27-02-17)
The rapid growth in popularity of movies made by emerging cinematographers in
recent years including corporate and commercial movies on the Internet and other
venues has increased the opportunities of shooting movies using cinema and regular
digital cameras, and it boosts demand for high-performance cinema lenses that
deliver high resolution and advanced scene-depicting capability.
Cinema lenses are the optimal choice to achieve a shallow depth-of-field and a
beautiful bokeh. However, since they are typically large, heavy and expensive, those
involved in online and other lower cost movie production often opt for
interchangeable lenses for digital cameras, which are more affordable and mobile.
The problem is that interchangeable lenses for digital cameras are designed
primarily for shooting still images, and therefore prone to focus shift and optical axis
shift while zooming, and so on. In response, Fujifilm has been working on developing
new cinema lenses that offer advanced optical performance with compact size and
operability to meet the needs of creative emerging cinematographers.
The MK lenses joining our cinema lens lineup inherit the FUJINON cine lenses’
advanced edge-to-edge optical performance and low distortion*1, and yet boast
compact and lightweight design as well as the level of outstanding cost performance
that has never been seen in conventional cinema lenses until now.
The MK series offers fast lenses with T2.9*2 speed across the entire zoom range,
enabling a shallow depth-of-field as well as a beautiful bokeh effect. The lenses will be
compatible with E-mount*3 cameras with the Super 35mm*4 / APS-C sensor and the X
Mount used in Fujifilm’s “X Series” of digital cameras (APS-C sensor). They achieve
advanced optical performance despite their compact and lightweight body by
incorporating the benefits of short flange focal distance*5 into optical design to the
maximum extent. The use of optical and mechanical design optimised for dedicated
movie lenses minimises focal shift and optical axis shift while zooming, and lens
breathing (change of angle of view during focusing) that are typically observed in
interchangeable lenses for digital cameras. The lenses feature three rings to enable
manual and independent adjustment of focus, zoom and iris (aperture), all with the gear pitch*6 of 0.8M (module). The focus ring can rotate fully up to 200 degrees to
facilitate precise focusing. This design makes the lenses comfortable to operate.
Fujifilm will firstly release the MK18-55mm (focal length of 18-55mm) for the E Mount
in early March, followed by the MK50-135mm (focal length of 50-135mm), also in the
E-mount this winter. Their X Mount versions (focal lengths of 18-55mm and 50-
135mm) are being developed for launch by the end of 2017.
FUJINON lenses offered by Fujifilm have been used at movie / CM / TV production
sites around the world for their advanced scene-depicting capability. Tapping into its
optical, high-precision processing and assembly technologies that have been
nurtured over the years in the cutting-edge field of movie production, Fujifilm will
introduce the “MK lens” series to the current lineup of the “HK / ZK / XK lenses” to
meet the diverse needs at the movie production frontlines.
*1 ”Distortion” refers to a phenomenon in which an image formed through a lens becomes partially contracted or extended at
*2 T-stop value is an index that indicates brightness of a lens based on its F-stop value and transmission rate. The smaller
the value, the greater amount of light the lens transmits.

many cinema cameras.
