Canon RF 24-70mm F2.8L IS USM Review
Sharpness at 24mm
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 24mm
At the centre of the image, sharpness is very good at f/2.8, but gets a bit sharper again at f/4. It remains very sharp at f/5.6 and f/8 before getting ever so slightly softer at f/11. It’s a little bit softer again at f/16, before showing the softest results at f/22. That said, you only see slight evidence of softness at 100%, the overall impression of detail is very good. At the corners of the image, the sharpness is best between f/11 and f/16.
