Canon RF 15-35mm F2.8L IS USM Review
Canon RF 15-35mm F2.8L IS USM 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 15-35mm 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 at the widest aperture of f/2.8 is good, but it is noticeably sharper when viewing at 100% when you get to f/4. It’s a little sharper again at f/5.6 and stays roughly the same at f/8 and f/11. Sharpness drops off a little bit at f/16 and f/22, but the overall impression of sharpness again remains good at normal printing and web sizes. At the corners, sharpness is best between f/8 and f/16.
