Samyang AF 45mm f/1.8 FE Review
Sharpness at 45mm
The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Samyang AF 45mm F1.8 FE lens was attached to a Sony A7 III 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.
The full frame at 45mm
The centre is acceptably sharp even when shooting wide open at f/1.8, with the peak performance achieved in the f/2.8-f/11 range. Diffraction sets in at at f/16. The edges are a little soft from f/1.8-f/2, sharpening up at f/2.8, with f/4-f/11 the optimum settings.
