Canon RF 28-70mm f/2 L USM Review
Canon RF 28-70mm f/2 L USM Sharpness at 28mm
The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Canon RF 28-70mm f/2 L USM lens was attached to a Canon EOS 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.
The full frame at 28mm
Center and edge sharpness are both excellent wide open at f/2 and outstanding between f/2.8 and f/11. At f/16 and f/22 sharpness across the frame is beginning to drop-off a little due to diffraction, but is still commendably high.
