Canon EF 100mm f/2.8L Macro IS USM review
Canon’s L-series EF macro lens with Hybrid IS, a long-time reference for 1:1 macro on DSLRs, at about $1,449 from a dealer. The listing itself gives almost no detail.
The EF 100mm f/2.8L Macro IS USM gives 1:1 magnification with stabilization and an L-series build. It also works as a portrait lens on full frame.
Macro basics
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. At 100 mm, the working distance leaves room for light between lens and subject.
The listing
This Amazon.com page is sparse: a UPC and a weight. iPro Photo sold it at about $1,449.
Which Canon macro to buy
On a Canon DSLR, this is the premium choice. On an RF mirrorless body, the RF100mm and RF85mm on this shelf are better matches.

What people ask before they commit
Is this better than the RF 100mm Macro?
For an RF body, the RF100mm F2.8 L Macro IS USM on this shelf reaches 1.4× and costs less on today’s listings. The EF lens makes sense on a DSLR.
What does 1:1 mean?
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.
Why so little information on the listing?
The listing carries only a UPC and a weight. The facts above come from the lens name and the product table.
