FeatureA telephoto zoom packed with the latest technology

Optical design for first-class telephoto zoom image quality

To deliver the best image quality in its class, this exceptional telephoto zoom uses an optical construction comprising of 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 zoom mechanism means the lens doesn't change length so the 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 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* is used for high-speed AF. By reducing the weight of the focus lens and mounting the Triple Linear Motor at intervals of 120 degrees, high-speed, quiet autofocus 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.

The best image stabilization performance in its class

Thanks to a high-performance gyro sensor and unique algorithm that cancels drift, the FUJINON XF50-140mmF2.8 R LM OIS WR lens delivers the best image stabilization performance in its class. Combined with a bright F2.8 aperture, hand-held shooting is possible in new environments 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 can be operated down to -10°C, 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, as well as the exterior of the lens body, for a high-quality finish. Applying their long-term experience and wide knowledge of top-end professional lens fields such as Broadcasting and CinemaScope, Fujifilm has designed the texture and torque on the rings for smooth, accurate 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 DSLR*, considerably reducing the photographer’s burden.

The AF+MF function allows seamless manual focusing. After pressing the shutter to autofocus on the subject, fine adjustments can be made using the manual focus ring.*6
