Samyang Premium MF 85mm f/1.2 Review

December 8, 2016 | 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 Premium MF 85mm f/1.2 lens was attached to a Canon 5DS R 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.

Both center and edge sharpness are excellent between f/4 and f/8, but there's obvious softness evident wide open at f/1.4 to f/2.8 in both the centre and edges of the frame. At f/11, f/16 and most notably f/22 the overall sharpness is beginning to drop off substantially.
