Product details:

Fuji 50-140mm F2.8 WR OIS XF Lens is a high performance, weather resistant telephoto zoom designed for use with Fuji X Series compact system cameras. The lens features a versatile focal length and a constant f2.8 aperture, making it suitable for a wide range of photographic applications including sport, travel, wildlife and night time photography. The lens is also equipped with the world's first Triple Linear Motor which uses an inner focusing system to maximise portability and ensure AF operation is quick, smooth and quiet. As with other Fuji XF lenses, the 50-140mm offers an all-metal barrel construction and an aperture control ring. Fuji'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 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?? high speed, quiet AF is possible. By applying seals to each portion of the barrel, it makes this lens weather-resistant, dust-resistant and -10??é low temperature operation. Fuji 1.4X XF TC WR Teleconverter is capable of multiplying the focal length of compatible lenses by 1.4x. When mounted, the converter increases the lens' aperture by one f-stop, however it's optical design is constructed of 7 elements in 3 groups and maintains the optical performance of the original lens. The teleconverter is weather and dust resistant and operates at temperatures as low as -10oC.An inner zooming mechanism means the lens does not change length so the lens' balance remains the same throughout the zoom range.
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.
