... but since you weren't only asking for "the best" which is "the most expensive" most of the time: the older "golden ring" 100/2.8 macro is very cheap to get used and the sharpness is nearly up par with the more expensive version. If you really shoot macro objects you might be using a tripod anyway (i.e. IS won't help) and at very close distance IS doesn't help much or not at all. The one drawback of the non-L version is missing weather sealing, so you have to watch out for dust or sand.Joellll said:Extra vote for the 100L here.

Jamesy said:A cheap entry level macro lens would be the 50/2.5 which is a 1:2 lens rather than the majority of the ones mentioned here which are 1:1.

To the OP original question
*All Canon*
Good = 50/2.5
Better = 100/2.8 or 60/2.8 EF-s
Best = 100/2.8 L
A buddy of mine has the Tamron 90 and says it is good.
