Sharpness at 50mm

For these sharpness tests the Fujifilm XF 50mm 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 excellent from the widest aperture of f/2, dropping off slightly at the narrowest aperture of f/16, due to diffraction. When viewed at normal printing or web sizes, this slight softening isn’t noticeable, but you can just about see it when viewing at 100%. The edges aren't as sharp as the centre, particularly at wide apertures. The sharpest results can be seen at f/8-f/11.
