Yes, the Canon EF 100mm f/2.8 IF USM model...internal focusing system, USM focus motor, also called "the second version", the one with the internal focusing system, not the one that the barrel extends way out on at minimum focus distance...I owned one for years, sharp lens, but kind of ugly sharp-sided bokeh balls on OOF highlights due to its 8-bladed diaphragm opening. In many close-up situations, there will be visible out of focus bokeh balls from this lens. Focusing is also somewhat slow-ish for a USM prime lens, but the used market price is low on this lens. Look also at the Tamron 90mm AF-SP macro, in any of three versions made over the last 15 years or so. Tokina's 100mm f/2.8 AT-X Pro model has received pretty good reviews as a value lens with good image quality. Not sure why anybody would limit themselves to Canon-only macro lenses: the Tamron 90 is clearly superior to the 100/2.8 EF I mentioned above, and is like the eighth refinement of a design that Tamron originated in the 1970's. Tamron's 90 AF-SP is probably their absolute crown jewel, and has been for 30 years, whereas Canon's V1 and V2 100/2.8 macros were seemingly afterthoughts. Canon's aged 180mm macro is the lens they are best known for over the longest time frame in the macro lens realm. Long macro lenses have a lot of usefulness too, with 1:1 somewhere around 18 inches from the sensor plane of the camera, which is very handy.
