Covering the focal length range from an ultra wide 20mm to medium-wide 35mm angle, it provides 35mm equivalent fields of view of 16-28mm. This range is the widest in the GFX System and ideal for recording wide expanses of landscapes or cityscapes. The constant f/4 maximum aperture across the zoom range is coupled with the compactness and lightweight of the lens design and weather-resistant construction to enable it to be used on location and while travelling. The optical design consists of 14 elements in 10 groups and includes three aspherical elements, one ED aspherical element and three ED elements, which together control various types of aberrations to provide high resolution performance. Application of Nano GI (Gradient Index) coating minimises ghosting and lens flare.

Magnesium alloy is used for components around the lens mount to make it lightweight and robust at the same time. The lens barrel is weather-sealed in 12 places to ensure dust- and weather-resistance as well as the ability to operate at low temperatures. A fluorine coating on the front element repels moisture, dust and grease. 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. The lens structure is almost symmetrical with the aperture at the centre and use of the short flange focal distance to provide the optimum balance between image quality and weight/ size. The lens weighs just 725 grams and is approximately 112.5 mm long. It accepts 82 mm filters.

The GF20-35mm f/4 R WR lens is due for release this month ant an RRP of AU$4099. Click here for more information.
