Fujifilm XF 18mm F1.4 R LM WR Review
Sharpness at 18mm
For this test, the Fujifilm XF 18mm F1.4 R LM WR lens was attached to a Fujifilm X-S10 body, which was in turn mounted to a sturdy tripod. Exposure delay mode was activated. Tonal and colour variance across the crops are due to change in natural light during the session.
The full frame at 18mm
The centre is pleasingly sharp even wide open at f/1.4, with peak performance achieved in the f/2-8 range. Diffraction sets in at f/16.
The edges are acceptably sharp from f/1.4 through to f/2.8, with f/4 to f/11 the optimum settings.
