The Fujinon XF23mm F1.4 R is a fast prime for Fujifilm's X system of mirrorless cameras. It offers a moderate wideangle field of view equivalent to a 35mm lens on full frame (the same as the company's fixed-lens X100S). It has traditional aperture and manual focus rings, and the latter has distance and depth of field scales too. Like the company's XF14mm F2.8R, the 23mm is fully optically-corrected for distortion.
