Exceptional image quality The lens features 9 lens elements in 7 groups including one aspherical ED lens, which prevents spherical and chromatic aberrations. This ensures the lens delivers outstanding results and minimises variances in image quality at different shooting distances. Compact, lightweight and stylish design The lens weighs just 200g. The metal exterior uses the same design style as XF35mmF2 R WR and XF23mmF2 R WR for a robust, premium feel. The compact and stylish design almost completely eliminates mechanical vignetting* when using the optical viewfinder on the FUJIFILM X-Pro2 camera. The aperture and focusing rings feature precise click stops and smooth damping for easy operation. Fast and silent autofocus The inner focusing AF system uses a stepping motor to drive lightweight focusing elements for a fast, silent autofocus performance. Weather and dust resistant The lens is weather-sealed at ten points around the barrel making it weather and dust resistant. It will also continue to operate in temperatures as low as -10°C. Used with the weather and dust-resistant FUJIFILM X-Pro2 or X-T2 bodies means users can shoot confidently in light rain or dusty environments.
