Sharpness at 50mm

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.

Here again, the central sharpness is very good at f/2.8, before becoming excellent at f/4. It remains excellent at f/5.6 and f/8, before dropping off a little at f/11. It becomes a little softer at f/16 and again at f/22, but even at the narrowest apertures the overall impression of sharpness is very good when viewing at normal printing and web sizes. The corners of the image display the best sharpness between f/8 and f/11.
