Sharpness at 100mm
For this test, the Canon RF 100mm F2.8L Macro IS USM lens was attached to a Canon EOS R6 body, which was in turn mounted to a sturdy tripod. Exposure delay mode was activated. Tonal and colour variance across the crops are due to change in natural light during the session.

Both centre and edge sharpness are outstanding from wide-open at f/2.8 all the way through to f/16, with f/22 being slightly affected by diffraction, and f/32 even more so.
