On an APS-C DSLR it's excellent, except some AF problems with older models like 300D, 20D - on 30D/400D everything is perfect!reviewed January 7th, 2007 (purchased for $1,300)
On FF (5D) everything is perfect as well. Though some visible vignetting on 24mm at 2.8 thru 5.6 and on 70mm at 2.8.

On APS-C DSLR it's almost perfect - comparing to other canon lenses it has some yellow-green colour cast on photos - wasn't able to fix it thru various RAW converters. Still the cast is almost invisible, so there is nothing to worry about.reviewed January 7th, 2007 (purchased for $1,300)
On FF the lens shows some issues - distortion&vignetting at wide end wide open (from F4 thru 6.3).
Anyway, highly recommended for APS-C!

On APS-C it's very useful range 17-40 (27-60 eqv.), image quality excellent. Build quality up to the top!reviewed January 7th, 2007 (purchased for $700)
On FF image quality remains on high level, still extreme corners shows some softness - stoping down a few stops helps a lot. I'll suggest to use 17mm from F5.6+.
Highly recomended for nature photography!
9 out of 10 points and recommendedVery sharp from wide open, relatively lightnon-IS
Nothing much to say - it's almost perfect in any way of testing. Cant find some cons... maybe IS-version will be even better.reviewed January 7th, 2007 (purchased for $700)
So my opinion, if you dont want to pay much more for 70-200/2.8L IS - the lens is your choice. It has no visible flaws.
Highly recommended for APS-C or FF!

It's not "L" so the construction quality could be better.reviewed January 7th, 2007
Image quality is excellent. Macro is almost scary :) No bug cant be safe ;)
I recommend the lens for FF and APS-C DSLR.

On APS-C DSLR the lens is very useful as a portrait lens.reviewed January 7th, 2007 (purchased for $350)
Wide open softness can be used as an "soft" effect for portraits. Anyway right from the f2.0 it became very sharp (still not as sharp as 100/2.8 macro).
Can be used as an all-purpose lens and for low-light conditions on FF body.
