Canon RF 100mm F2.8L Macro IS USM review
Canon’s RF L macro, the first medium telephoto macro lens to reach 1.4× according to Canon, with Hybrid IS and a bokeh-shaping control ring, sold by Amazon.com for about $1,349.
Canon calls this the world’s first medium telephoto macro to reach 1.4×. For insects and small details, that extra magnification avoids cropping.
Stabilized close up
Up to 5 stops of IS, with Hybrid IS for the shift shake that dominates at macro distances.
Creative control
The SA control ring changes how out-of-focus areas look, smoother or crisper.
Seller
Amazon.com sold it at about $1,349.

What people ask before they commit
What does 1.4× mean?
The subject is projected 1.4 times larger than its real size on the sensor. A 1:1 ratio, also written 1.0×, means the subject is projected onto the sensor at its real size. A 0.5× lens projects it at half size.
What does the SA control ring do?
It adjusts spherical aberration to change the character of foreground and background blur.
Does it work for portraits?
Yes. 100 mm at f/2.8 is a good portrait lens on full frame.
