Canon RF 24-70mm F2.8L IS USM Review
Sharpness at 70mm
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 70mm
70mm is where we see the softest results, but it’s still very good at f/2.8, the widest aperture. It gets a little sharper at f/4, before displaying the sharpest results between f/5.6 and f/8 before dropping again slightly at f/11, again at f/16 and again at f/22. Once again, the overall impression of sharpness when not viewed at 100% is great. At the corners, the best results can be seen between f/8 and f/11.
