Fujifilm Announces the XF 50mm f/1.0 R WR: Autofocus, Huge Aperture, Weather Sealing

Fujifilm has announced the new XF 50mm f/1.0 R WR lens, dubbed the “world’s first autofocus lens with a maximum aperture of f/1.0.”

While definitely not a featherweight, the lens is relatively light at 1.86 lb (845 grams). It measures 4.07 inches (103.5mm) in length, 3.43 inches (87mm) in diameter, and like all other XF lenses, it is weather sealed, allowing it to be used under demanding conditions when paired with the right camera.

The lens will be available in the next month or so at a price of $1,499.95. The angle of view is equivalent to 76mm in 35mm format.

Victor Ha, Fujifilm’s senior director of marketing and product management, describes it as “an incredible tool for visual storytellers.” With such a wide maximum aperture, the autofocus “can achieve critical focus at very shallow depth of fields,” even under incredibly low lighting conditions. Fujifilm states that it can lock autofocus at a luminance level of -7EV when paired with the X-T4 or X-Pro3.

9 aperture blades create a rounded diaphragm in order to deliver smooth bokeh. 12 elements sit in nine groups, including one aspherical element and two extra-low dispersion (ED) elements in order to control spherical aberration. Here are the specifications in full:
