Sharpness at 35mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Canon RF 24-70mm F2.8L IS USM lens was attached to 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 35mm

Central sharpness is very good at f/2.8, the widest aperture, before rising to excellent at f/4 and f/5.6. It’s ever so slightly softer again at f/8, before dropping off a little more at f/11. The softest results can be seen at f/16 and f/22, but it’s only really evident if you’re examining the images at 100% - the overall impression of sharpness is excellent when viewing at normal sizes. At the corner of the image, the sharpest results can be seen at f/8 and f/11.
