Nothing against the Tamron. Great lens. Arguably as good or
slightly better than the Canon 100/2.8 as a macro lens... but... it
needs to be more than that, if it can, and the Canon is the best
candidate of the bunch to pull off the dual-use with the best
non-macro AF performance of the bunch by all the accounts I've been
able to find.
So.. can anyone comment on the Canon 100's NON-MACRO Autofocus
performance? Am I, an original AF 35mm SLR user and Digitial P&S
user going to find fault with it's AF performance? I want it to be
pleasurably fast, but it doesn't have to be so fast I wet myself
everytime I perform a half-press of the shutter! Slower than an
85/1.8 is fine. I just want/need it to be noteably faster than
what I'm accustomed to now... otherwise I'll reluctantly settle on
using it for Macro only (reconsider the Tamron, in that case) and
get an 85/1.8 to do the portrait and general purpose short-tele I'm
hoping for out of the Canon 100/2.8
Help?

Well just to confuse things further I ve read and found
(photographyreview.com from users at epinions.com and other places)
that the Tamron 90 f2.8 Macro might be a better choice. It is
priced between the ($460 canon and the $300 Sigma Macro lenses at
of 100 and 105 mm respectively) and it is optically better than
both unless one wants to use autofocus where the Canon is superior.
Not many use AF for Macro though. Another drawback is that the tube
extends a lot at macro and might scare away a subject. However, it
is about $60 cheaper, comes with a 6yr warranty (the USA model) and
comes with a hood (even without one the lens is very recessed
apparently and there is thus little flare even without a hood).
Why isnt this easier ?
