Photography Blog posted their exhaustive Canon RF 100mm f/2.8L Macro IS review. They seem to be rather fond of the lens. They gave the lens a “highly recommended” and a 4.5/5 rating. From their conclusion:
The Canon RF 100mm F2.8L Macro IS USM is a superb macro lens boasting class-leading magnification, outstanding sharpness, impeccable build quality and a unique Spherical Aberration Control ring.
It delivers outstanding sharpness at both the centre and edges of the frame throughout most of its aperture range, even performing brilliantly when shooting wide-open at f/2.8.
There’s some vignetting which requires you to stop down by at least 2 f-stops to prevent it completely, but there’s little evidence of chromatic aberrations. Distortion is very well controlled even when shooting in the RAW format when the camera body doesn’t apply any automatic corrections.
