Sharpness at 130mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Fujifilm GF 100-200mm F5.6 R LM OIS WR lens was attached to a Fujifilm GFX 50S camera body, which in turn was mounted on a sturdy tripod. Self-timer mode was activated. Slight tonal changes are due to slight changes in natural light during the session.

Centre sharpness is impressively high throughout almost the entire aperture range, with peak performance between f/5.6-f/16. Corner sharpness is also excellent, again producing optimal sharpness at f/5.6-f/16. Diffraction starts to kick-in at f/22.
