FUJIFILM Corporation (President: Kenji Sukeno) has unveiled the FUJINON GF80mm F1.7 R WR Lens (GF80mmF1.7), the world’s first 1 F1.7 interchangeable lens with autofocus designed for a large format system. It has a standard focal length of 80mm (a 35mm equivalent of 63mm). This large-diameter autofocus (AF) prime lens is the fastest lens among Fujifilm’s G Mount lenses and the highly anticipated bokeh produced from GF80mmm F1.7’s wide aperture is sure to provide an incredible aesthetic quality to any image.
GF80mm F1.7 R WR features nine rounded diaphragm blades that can be stopped down to provide edge-to-edge sharpness or opened up to produce images with beautifully smooth bokeh, with astounding separation between a subject and its background, from any GFX System camera. Comprising 12 lens elements in nine groups, including one aspherical element and two Super ED elements, this lens is optimally balanced to control spherical aberration and deliver a quality of bokeh so aesthetically pleasing that it most likely cannot yet be reproduced by any other Large Format lens.
The use of ultra high-precision glass moulding technology means both surfaces of the aspherical lens element can be manufactured to within a tolerance of 1/100,000th of a millimetre. This is five times more accurate than regular moulding and reduces the onion-ring effect that can oftentimes negate the attractive effect bokeh can have on the out-of-focus sections of an image.
GF80mm F1.7 features a powerful DC motor that has enough torque to drive the focus group of six lens elements – which includes the aspherical element – to deliver accurate and reliable autofocus, even when the lens is wide-open at F1.7 and depth of field is extremely shallow. The lens also supports the Face / Eye AF function, which uses an advanced focusing algorithm to accurately acquire focus on a subject’s face or eye even when they are moving within the frame.
GF80mm F1.7 brings a half-a-stop of improvement to GFX100’s AF scene luminance limit – moving from EV-5.0 to EV-5.5 – making GFX100’s autofocus now even more capable in low-light.
Measuring 99.2mm (3.9in) long and weighing just 795g (1.75lb), with a filter thread size of 77mm, GF 80mmF1.7 is practically sized and suited for both on-location and in-studio applications.
Weather-resistant seals have been applied to the lens barrel at 10 locations on the lens to protect it against dust and water, while also providing it with the ability to operate at temperatures down to -10°C (14°F). The front lens element is also coated with fluorine to repel dirt for an added layer of protection.
