|XF||The lens is designed for Fujifilm digital mirrorless cameras.|
|R||The lens is equipped with aperture ring.|
|LM||The lens is equipped with linear motor to provide smooth, very fast and virtually silent autofocus. Learn more|
|OIS||The lens is equipped with optical image stabilizer. The stabilizer allows to increase the shutter speed by several stops and shoot handheld in such lighting conditions and at such focal lengths where without stabilizer you will have to use tripod, decrease the shutter speed and/or increase the ISO setting which can lead to blurry and noisy images.|
|WR||Dust-proof and Weather Resistant lens.|

Design and Features
The lens barrel is large, heavy, dust-proof and water-resistant, made of metal. The lens mount is metallic. The rubberized zoom and focusing rings both rotate smoothly and are finely ribbed in order to provide a good grip and prevent slippage of fingers. The front part of the barrel extends by 6cm with focusing to focal length of 400mm.
The lens features a zoom lock lever to keep the zoom ring fixed at the shortest focal length of 100 mm. This function is convenient for carrying a camera with the lens on a strap because it prevents the lens from extending.
The focusing ring is not physically coupled with the focusing mechanism and works electronically (focus-by-wire) - turning of the ring actuates an electric motor that moves the focusing group of the lens to the proper position to achieve sharp focus.
The lens lacks focusing mode switch, therefore you have to set the automatic or manual focus mode from the camera.
The lens features focusing distance range limiter which allows to choose between the following focusing distance ranges:
|FULL||Full range of focusing distances.|
|5 m - ∞||Range of focusing distances suitable for shooting distant subjects.|
By setting the suitable focusing distance range, the actual autofocusing time can be shorter.
The lens uses front filters with standard size of 77 mm which are easy to find. However, filters of such size are more expensive and mainly used with professional lenses.
The filter thread does not rotate during focusing which allows convenient use of different types of filters (including but not limited to polarizing and gradient).
Fujifilm offers a deep circular bayonet-type lens hood as a part of the package featuring a slide-out window which enables rotation of polarizing filter without removing the lens hood.
A fluorine coating has been applied to the outer surface of the front lens element to repel particles of dust, water or oil drops for easier cleaning of the lens surface.
The lens is equipped with twin linear motors, the autofocus is virtually silent and fast.
The lens features optical image stabilizer, which, according to the manufacturer, compensates up to 5 stops of shutter speed. Theoretically it allows to capture sharp images of static subjects at shutter speeds down to 1/12 second at focal length of 400 mm(*).
