Fujifilm has formally announced its XF 50mm F1.0 R WR portrait prime lens, the world’s first autofocus lens with a maximum aperture of F1.0, designed for mirrorless cameras. The XF50mmF1.0 R WR is the 35th interchangeable lens for the lineup of X Series digital cameras.

“We’re really excited about the XF50mmF1.0 R WR,” said Victor Ha, senior director of marketing and product management for the Electronic Imaging Division of FUJIFILM North America Corporation. “Not only is it the fastest interchangeable lens Fujifilm has ever produced, but it’s also an incredible tool for visual storytellers to use in telling their stories because its autofocus can achieve critical focus at a very shallow depth of fields.”

The XF50mmF1.0 R WR consists of 12 lens elements in nine groups and also contains one aspherical element and two extra-low dispersion (ED) elements to achieve optimum control of spherical aberration. Used at or near to its maximum F1.0 aperture, XF50mmF1.0 R WR can produce an astonishingly narrow depth-of-field. Its precision-engineered, rounded diaphragm produces large, smooth bokeh for a professional look. Use this new power in selective focus to keep only the subject’s eyes in focus and to create captivating, close-up character images. “But it’s not just for portraits,” said Ha. “Take this lens out onto the street or into a lifestyle session and you’ll turn cluttered locations into clean backdrops with unrivaled subject separation.”

The very wide, maximum aperture on XF50mmF1.0 R WR means there are more options when it comes to making images in low-light conditions. At night, or in darkened interiors, XF50mmF1.0 R WR offers the widest apertures yet seen on an XF Lens, allowing more light to be drawn in when capturing your image. The FUJINON XF50mmF1.0 R WR lens also easily achieves fast shutter speeds that freeze movement and keep ISO settings lower for detail-rich results. Alternatively, combine high ISO settings with the F1.0 aperture for incredible versatility and use in other low-light applications like astrophotography.

As the world’s first autofocus F1.0 lens made for any mirrorless system, including full-frame, XF50mmF1.0 R WR brings more light to the sensor than any previous XF lens, making it possible for the autofocus to operate on FUJIFILM X-Pro3 and X-T4 cameras at -7EV luminance level. Leaving behind a previous limit of -6EV luminance level with other XF lenses X Series users now have fast and precise low-light autofocus, even in near-darkness. With the added benefits of on-sensor Phase Detection Autofocus (PDAF), Face/Eye AF and a powerful DC (direct current) motor, precise and fast autofocus at shallow depths of field is now also a possibility.

To make the most of its super-shallow depth-of-field, focusing must be precise. As a result, XF50mmF1.0 R WR has a focus ring that has been designed to be more accurate than any previous XF Lens. This makes it possible to adjust the focus from the minimum focusing distance to infinity very precisely. For this, XF50mmF1.0 R WR uses 120° of rotation in its focusing ring to let you focus manually with minimal error – and to achieve accurate focus when using your X Series camera’s Focus Peaking and Focus Assist modes. The 120° of rotation also makes autofocus movements notably precise and deliberate, while the lens’ engineering is designed to minimize focus shift effects during image-making.

Despite being a fast, F1.0 lens, XF50mmF1.0 R WR is a lens you can use to make amazing pictures almost anywhere. Measuring 4.07in (103.5mm) long and weighing 1.86 pounds (845 grams), the lens is still quite compact and portable. Like all other weather-resistant XF Lenses, it is sealed in 11 locations to protect against moisture and dust, as well as being capable of use in temperatures down to 14°F (-10°C). When allied to a similarly specified, weather-resistant X Series mirrorless digital camera body, XF50mmF1.0 R WR lets you make unique images in the toughest environments.

FUJIFILM says the XF 50mm F1.0 R WR will be available in Fall 2020 at a price of $1499 USD.
