I have these 2 on my potential shopping list to replace my 17-85 on my 40D. I already have a 70-300mm which sorts out my Tele end, and I'm looking to buy a 10-22mm for Landscape work however for my general walkabout, I want something sharper than what I already have.
I have seen a mate's 24-105 perform on a 40d and it actually seems to provide a slightly different colour casting to my 17-85 (and should I say preferable).
This is shooting in RAW and looking at them side by side.
The 15-85mm really appeals as it is cheaper, is being compared to by many as optically close to the 24-105mm and has the wider end for a crop body.
Is the 15-85mm a considerable upgrade over the 17-85mm, and will it provide a different colour cast to the 24-105mm simply because its not an L lens?
