Sharpness at 23mm

For these sharpness tests the Fujifilm XF 23mm f/2 R WR lens was attached to a Fujifilm X-Pro2 body, which in turn was mounted on a sturdy tripod. Slight tonal changes are due to slight changes in natural light during the session.

Centre sharpness is good from the widest aperture of f/2, but it is sharpest from f/2.8 onwards. Due to diffraction, the lens is a little softer in the middle at f/11 and f/16, but it’s not likely to be too noticeable when viewing at normal printing and web sizes. Sharpness is also very good in the corners, but from f/5.6-f/11 is the optimum sharpness levels.
