Samyang XP 50mm F1.2 Review

Sharpness at 50mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Samyang XP 50mm F1.2 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/2 and f/11, but there's obvious softness evident wide open at F1.2 to f/1.8 in both the centre and edges of the frame. At f/16 the overall sharpness is beginning to drop off due to diffraction.
