Fujifilm Fujifilm Gf-Mount>GF 20-35mm F/4 R WR Lens

Capture Every Detail with the GF 20-35mm F/4 R WR

This zoom lens offers a focal length range from the ultra-wide-angle 20mm to the wide-angle 35mm (equivalent to 16mm – 28mm in the 35mm format). With its ultra wide-angle coverage, you can capture expansive landscapes or cityscapes with precise details in high resolution. Plus, the wide angle of view allows you to take photos of a subject from a close distance to the camera, giving you a broader field of view than the human eye.

The convenience of having the constant F4 open aperture across the zoom range is coupled with the compactness and light weight of the lens design. It is perfect for users who travel for many hours in search of vast expanses of wilderness and for shooting a full view of a small room.

The GF 20-35mm F/4 R WR consists of 14 elements in 10 groups, including three aspherical elements, one ED aspherical element and three ED elements, effectively controlling various types of aberrations to provide advanced image resolving performance. The new lens is applied with the Nano GI (Gradient Index) coating that effectively controls angled incident rays to minimise ghosting and lens flair, thus achieving greater image clarity.

The GF 20-35mm F/4 R WR’s ultimate compact design means it weighs just 0.725kg despite being a constant F4 ultra-wide-angle zoom lens. Ultra wide-angle lenses tend to be huge, but Fujifilm has designed this lens compact to make it more comfortable for landscape photographers who spend many hours outdoors.

Fujifilm GF 20-35mm F/4 R WR lens Features

The Fujifilm GF 20-35mm F/4 R WR lens extends the wide angle region of the GF lens lineup in pursuit of premium image quality. The new lens covers focal lengths from the ultra-wide-angle 20mm to wide angle 35mm (equivalent to 16-28mm in the 35mm format) that is the widest in the lineup of FUJINON’S GF lenses to capture information dense subject matter in a wide expanse of landscape or cityscape and to take advantage of the unique perspective of a wide angle lens.

The GF 20-35mm F/4 R WR consists of 14 elements in 10 groups, including three aspherical elements, one ED aspherical element and three ED elements, effectively controlling distortion and chromatic aberration to achieve advanced image-resolving performance. This is why the lens can present, with superior precision, all information of subject matter recorded within a wide angle of view.

The lens is applied with Fujifilm’s unique Nano GI Coating technology. It seamlessly changes incoming light’s refractive index as it enters the lens to mitigate light reflection, thereby effectively reducing ghosting and lens.

Compact Design That Brings Portability to Large Format Equipment

The lens is structured almost symmetrically with the aperture at the centre to achieve optimum aberration correction and compact, lightweight design simultaneously. The short flange focal distance, a unique characteristic of mirrorless photographic equipment, has been utilised to the maximum extent to perfect optical design that has the optimum balance between image quality and weight/ size. The lens weighs just 0.725kg and measures approx. 11.25cm. The use of the highly versatile 82mm filter thread means users can choose from a variety of filters when shooting landscape. The Inner Zoom system is adopted to keep the full length of the lens constant, contributing to its lightweight and ease of zooming.

A total of four aspherical elements are used in each of the lens groups to optimise the overall number of elements and their configuration, thus efficiently correcting aberrations to maintain advanced image quality while keeping the compact form factor. The concave lens surface of strong curvature, typically seen in ultra-wide-angle lenses, is applied with specialised coating with even thickness to reduce ghosting which occurs when the coating thickness is uneven.

Magnesium alloy is used for components around the lens mount to make it lightweight and robust at the same time. The shape of components has been updated to keep the lens mount area slim and to accommodate the Inner Zoom system to keep the lens length constant. These features make the lens easy to hold and manoeuvre, unlike other traditional bulky ultra wide-angle zooms.

A Rugged Lens That is Dust and Weather Resistant and Capable of Operating At Temperatures As Low As -10°C

The lens barrel is weather-sealed in 12 places to ensure dust- and weather resistance as well as the ability to operate at temperatures as low as-10°C. The front lens element is applied with a fluorine coating to repel water and offer protection against stains. This means users can enjoy the lens with peace of mind to shoot landscapes in snow-blanketed fields, in the tropics, or outdoors in harsh weather conditions.
