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
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.
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.
