Fujifilm XF 18-135mm F3.5-5.6 R LM OIS WR Review
Fujifilm XF 18-135mm F3.5-5.6 R LM OIS WR Sharpness at 100mm
For these sharpness tests the Fujifilm XF 18-135mm F3.5-5.6 R LM OIS WR lens was attached to a Fujifilm X-T1 body, which in turn was mounted on a sturdy tripod. Slight tonal changes are due to slight changes in natural light during the session.
The full frame at 100mm
At 100mm the centre is slightly soft wide open, with peak performance achieved in the f/8-11 range. Diffraction sets in at around f/16, with its effects becoming more visible at f/22.
The edges are somewhat soft at f/5.6 but sharpen up very nicely at f/8, with f/11 the optimum setting.
