All Canon lenses are compatible with all DSLRs and the only lenses I've heard of giving problems are old Sigmas but quite a few people have had them rechipped--except for some very old ones I guess.

 The new Canon EF-S 60 mm 2.8 macro must be a nice replacement for the 
Tamron 90 mm. Slightly longer than the Tamron on an APS DSLR.
