Fujifilm has announced the Fujinon XF 50-140mm F2.8 R LM OIS WR weather-resistant X-series zoom lens designed to accompany the water- and dust-resistant Fujifilm X-T1 mirrorless camera.
The XF 50-140mm f/2.8 R LM OIS WR is a new high-performance, weather-resistant X Series telephoto zoom lens with a constant aperture of F2.8, powerful image stabilization and the world’s first Triple Linear Motor which enables quiet and high-speed auto focus.
The Fujinon XF 50-140mm f/2.8 R LM OIS WR has an optical construction with 23 elements arranged in 16 groups, including 5 ED lens elements, and 1 Super ED lens element with low dispersion characteristics. The lens offers a 35mm focal length equivalent of 76-213mm,

Fujifilm announces the FUJINON XF50-140mmF2.8 R LM OIS WR
A new high-performance, weather-resistant X Series telephoto zoom with a constant F2.8 aperture, powerful image stabilsation and the world’s first Triple Linear Motor
FUJIFILM Corporation (President: Shigehiro Nakajima) is proud to announce that a new FUJINON XF50-140mmF2.8 R LM OIS WR will be added to the X Series interchangeable lens lineup in late November 2014.
The FUJINON XF50-140mmF2.8 R LM OIS WR has a focal length equivalent to 76-213mm*1, and a constant f2.8 aperture throughout the range. With a lens construction of 23 glass elements in 16 groups, which features five ED lens elements, and one Super ED lens element with low dispersion characteristics comparable to a fluorite lens, chromatic aberrations have been substantially reduced. Furthermore, the use of a new Nano-GI (Gradient Index) coating technology ensures this high-performance optic delivers results befitting its flagship XF telephoto zoom lens status.
The length of the lens barrel remains constant throughout the entire zoom range, and features a weather resistant and dust-resistant finish that can also work in temperatures as low as -10°C. Thanks to a high-performance gyro sensor, a unique image stabilisation algorithm and the bright F2.8 aperture hand-holding is possible in a wider range of conditions, while the world’s first Triple Linear Motor allows comfortable shooting with fast, quiet autofocusing.

(1) Optical design for flagship telephoto zoom image quality
To deliver the best image quality in its class, this luxurious telephoto zoom uses an optical construction comprising 23 glass elements in 16 groups, with five ED lens elements and one Super ED lens element comparable to a fluorite lens. This maximises the reduction of chromatic aberrations and delivers high resolving power.
Applying Fujifilm’s unique HT-EBC (High Transmittance Electron Beam Coating) to the entire area of the lens surface ensures ghosting and flare are controlled for sharp, clear images. Also, using the newly developed Nano-GI (Gradient Index) coating technology, which alters the refractive index between glass and air, ghosting and flare are effectively reduced for diagonal incident light.
Like other XF lenses, seven rounded aperture blades create a smooth, circular bokeh. An optical design has been used to produce beautiful bokeh at both front and back.
An inner zooming mechanism means the lens does not change length so the lens’ balance remains the same throughout the zoom range.
By combining this lens with an X Series camera body*3 with Lens Modulation Optimiser*2 (LMO) technology, the performance from the lens is improved even further. LMO corrects for diffraction*4 to produce images with edge-to-edge sharpness and create a realistic three-dimensional effect, even at small apertures.
*2 Fujifilm’s own image processing function that corrects the optical effects of diffraction, based on the optical performance of each lens.
*3 Supported by the “FUJIFILM X-T1” and “FUJIFILM X-E2” as of August, 2014.
*4 Phenomenon that occurs when the shooting with a narrow aperture in which fine images that should originally be sharp become blurred.
(2) High-speed, quiet autofocus thanks to the world’s first Triple Linear Motor
An Inner Focusing System*5 is used for high-speed AF. By reducing the weight of the focus lens and mounting the Triple Linear Motor at intervals of 120°, high-speed, quiet AF is possible.
Faster AF is possible when by combining this lens with an X Series camera body offering Phase Detection AF. Combined with the near-silent shutter sound, photos can be taken unnoticed in quiet locations. As AF operates using a signal from the imaging sensor, extremely high-precision focusing is possible. With a minimum working distance of 1m for the entire zoom range, this lens is also great for close ups.
*5 Method for moving the small lenses in the middle and rear sections of the lens, without moving the large lenses composing the front of the lens.
(3) The best image stabilisation performance in its class
Thanks to a high-performance gyro sensor and unique algorithm that cancels drift due to temperature changes, the XF50-140mm delivers the best image stabilisation performance in its class. Combined with a bright F2.8 aperture, handholding is now possible in new areas for a telephoto zoom.
(4) Weather resistant, dust-resistant and freezeproof to -10°C low-temperature operation
By applying seals to each portion of the barrel, the lens is weather-resistant, dust-resistant and -10°C low-temperature operation, making it the perfect companion for the X-T1, which has the same levels of protection.
(5) High build quality and comfortable operation
Both the focus and aperture rings are metal, plus metal is also used on the exterior of the lens body for a high-quality finish. Thanks to long-term experience and broaden know-how for other top-end professional lens fields such as Broadcasting and CinemaScope, the texture and torque on the rings makes for comfortable shooting even for delicate manual focusing. The lens mount is made from brass for improved strength.
Combined with a camera body, the lens is approximately 60% of the weight of a full-size system*6, considerably reducing the burden on the photographer.
The AF+MF function enables seamless manual focusing. After pressing the shutter to autofocus on the subject, fine adjustments can then be made using the manual focus ring.*7

*7 A function allowing seamless manual focusing by rotating the focus ring while pressing the shutter halfway during AF lock. A firmware upgrade is required for the camera body in order to use this function. (Applicable models: X-Pro1/X-E1/X-E2/X-T1)
