Fujifilm XF 18-55mm F2.8-4 R LM OIS Review
Sharpness at 18mm
For these sharpness tests the Fujifilm 18-55mm lens was attached to a Fujifilm X-E1 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 remarkably sharp wide open, with peak performance achieved in the f/4-8 range. Diffraction sets in at around f/16, with its effects becoming more visible at f/22.
The edges are somewhat soft at f/2.8 but sharpen up very nicely at f/8, with f/11 the optimum setting.
