Fujifilm XF 18-135mm F3.5-5.6 R LM OIS WR Review
Sharpness at 18mm
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 18mm
At 18mm the centre is pretty sharp wide open, with peak performance achieved in the f/4-11 range. Diffraction sets in at around f/16, with its effects becoming more visible at f/22.
The edges are not so good, though, being soft at f/3.5-f/5.6 and not sharpening up until f/8, with f/11 the optimum setting.
