Recently upgraded from 400d to 7d and loving the new body. i am now thinking about upgrading lenses to get the best from my new toy. I currently have a sigma 17-70 non os and 70-300apo. I also have the canon 18-200is i bought for going to Italy with the 400d last year. I would still like to have something a bit general purpose but better IQ than I have.
Having read numerous foriums and reviews i am now more confused than ever. Lenses I have looked at are.

24-105L apparently great lens but not very wide on the 7d and expensive.
15-85is usm got the reach and plenty wide enough for my needs. Not so worried about the low light performance as have 430 flash. but how good is it compared to what i have.

also looked at the newer 17-70 0s sigma and giving the old one to the wife with the 400d she is now using with the old kit lens, and maybe the Tamron 70-300mm f4-5.6 SP Di VC USD.

I know now that the suprzoom avenue was the wrong one to go down.
