Sharpness at 55mm

Our sharpness tests are carried out by photographing a real-world subject rather than a test chart. The Fujifilm GF 55mm F1.7 R WR was attached to a Fujifilm GFX 100 II camera, which in turn was mounted on a sturdy tripod. Self-timer mode was activated to steady the camera completely. Any slight tonal changes you may see across the crops are a result of slight changes in natural light during the shooting session.
