Never completely satisfied
I owned this lens for six years, now sold. This was bought to be my go-to, walk around lens on a EOS 40D.
On the plus side, low light performance was stellar.
Not so great? I'm no pixel-peeper but images always came out just that little bit soft for my taste (as compared with my EF 70-200 f/4L, which always delivered far sharper and brighter images). Maybe I was the unlucky one to buy That Lens? Always left me wondering where all that money went, especially when I had to buy a hood separately! Excuse me Canon?
