A telephoto zoom offering the most frequently used telephoto focal lengths, equivalent to 76mm* to 213mm*, and a maximum aperture of F2.8. It features the latest technology, including dust / water and low temperature resistance, a triple linear motor, and the world's top image stabilization technology in its class, so that users do not miss a shot in any conditions. Its advanced performance makes it a perfect choice, not only for portraiture and snapshots, but also to capture fast-moving subjects in sports or wildlife photography, and for general outdoor nature photography. 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 maximizes 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* with Lens Modulation Optimizer** (LMO) technology, the performance from the lens is improved even further. LMO corrects for diffraction*** to produce images with edge-to-edge sharpness and create a realistic three-dimensional effect, even at small apertures. High-speed, quiet autofocus thanks to the world's first Triple Linear Motor An Inner Focusing System*4 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. World's most advanced 5.0-stop image stabilization function Thanks to a high-performance gyro sensor and unique algorithm that cancels drift, the FUJINON LENS XF50-140mmF2.8 R LM OIS WR delivers the best image stabilization performance in its class. Combined with a bright F2.8 aperture, handholding is now possible in new areas for a telephoto zoom. Weather resistant, dust-resistant and -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 FUJIFILM X-T1, which has the same levels of protection. 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. 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*5, 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.*6 Compatible with the 1.4x and 2.0x Teleconverter The lens offers compatibility with the 1.4x Teleconverter (XF1.4X TC WR) and 2.0x Teleconverter (XF2X TC WR).

A telephoto zoom designed for use in trying conditions, Fujifilm's XF 50-140mm f/2.8 R LM OIS WR Lens is a weather-sealed optic spanning the popular 76-213mm equivalent focal length range and featuring a constant f/2.8 maximum aperture. Built for Fujifilm X-mount mirrorless digital cameras, this fast zoom further extends itself through the incorporation of a sophisticated lens design, highly effective optical image stabilization system, and a Triple Linear Motor AF system for refined performance.

Comprised of 23 elements in 16 groups, the optical design incorporates five extra-low dispersion (ED) elements and one Super ED element to markedly reduce chromatic aberrations and color fringing throughout the zoom range. Additionally, a Nano-GI coating has also been applied to elements to alter the refractive index in between elements to minimize surface reflections and prevent lens flare and ghosting. This lens also sees the incorporation of 20 distinct weather seals across the barrel to render it both moisture and dust-sealed for use in inclement conditions as low as 14°F. An inner focusing and inner zoom design further help to prevent dust from entering the lens while also benefiting overall handling.
