I'm jealous. I had the non IS 70-200L f4 lens and upgraded to the 70-300L as soon as it came out. The lens I got was horrible. Worse than the 70-200L f4, strong vignetting, bad sharpness in the corners and awful chromatic aberration. I sent it back two days later. It sounds like I had a bad copy. I then bought the 70-200L IS f4 and enjoy it, but wish the 70-300L would have worked out. At this point I think I will just save up for the 70-200L IS 2.8 II someday.

Wow I think you must've gotten a bad copy. I will say it does have quite a bit of CA at 70mm, noriceably more than the 70-200 f/4 IS and I think even more than than the non-L or Tamron there, but you can largely clean it up in ACR/etc. and it's easily the sharpest of them all, despite that, at 70mm. Mine had less CA at 200mm than the others though.
