I've got plenty in my SmugMug galleries but I'm sure all these pictures (or at least 98% of them) in this gallery, this one and this one were taken with that lens. (dead links removed)
I like it lots!
I had the abysmal Canon EF 75-300mm f/4-5.6 III USM (dead link removed) and that was a total mistake. Compared to 75-300mm this one is super terrific. It isn't an L series lens (I sure can't afford one, how about you? *wink*) but it's pretty good. Chromatic aberration is tolerable as with the 75-300mm it was always there on each and every shot. Not only that but the 75-300mm's focus was so darn soft, it always looked slightly out of focus.
Before buying the 70-300mm IS, I read a lot of reviews and most were positive. I read reviews of the 75-300mm AFTER buying it... *rolleyes*
Anyway, I have some links to reviews for the 70-300mm IS right here. (dead link removed)
I posted some photos in my blog when I was testing the lens here and here. (dead links removed)
