Samyang AF 75mm f/1.8 FE Review

April 28, 2020 | Mark Goldstein |

Sharpness at 75mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Samyang AF 75mm 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 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.
