Fujifilm has recently announced the world’s first autofocus lens with a maximum aperture of f/1.0. The FUJINON XF50mm f/1.0 R WR lens is designed for mirrorless cameras and is the 35th interchangeable lens Fujifilm has released for their X Series digital cameras.

The XF50mm f/1.0 R WR is an ultra-fast mid-telephoto prime lens with a focal length of 50mm, equivalent to 76mm in 35mm film format, and is the company’s fastest interchangeable lens to date. Providing extremely shallow depth-of-field, the lens features a large-diameter design and beautiful bokeh effects, and delivers edge-to-edge sharpness. The inclusion of a DC autofocus motor into the lens allows for quick and accurate autofocus when images are captured at the maximum f/1.0 aperture. As well as this, Fujifilm states that the focus ring is eight times more accurate than any previous XF lens.

For times when manual focus is required, such as during video-recording, the manual focus ring provides 120 degrees of rotation to allow for precise, enhanced control and quick travel through the focus range to infinity. The lens is weather-sealed in 11 locations to protect it from moisture and dust, as well as being capable of use in temperatures down to -10°C. It tips the scales at 845g and consists of 12 lens elements in nine groups, including one aspherical element and two ED elements.

Practical for a variety of applications, those shooting portraits or in low-light setting (as dim as -7EV) will benefit most from the fast f/1.0 aperture.

The lens will be available in late September with an RRP of $2,799.
