Samyang AF 85mm F1.4 RF Review

June 8, 2020 | Mark Goldstein |

Sharpness at 85mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Samyang AF 85mm F1.4 RF lens was attached to a Canon EOS RP 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 pretty soft when shooting wide open at f/1.4, very good at f/2, with the peak performance achieved in the f/2.8-f/8 range. Diffraction starts to set in at at f/11. The edges are also soft from f/1.4-f/2, sharpening up at f/2.8, with f/4-f/8 the optimum settings.
