Sharpness at 85mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Canon RF 85mm f/1.2L USM DS lens was mounted on a Canon EOS RP 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 85mm

Center and edge sharpness are both excellent wide open at f/1.2 and outstanding between f/1.4 and f/11. At f/16 sharpness across the frame is beginning to drop-off slightly due to diffraction.
