p.1 #20 · p.1 #20 · What do you think about the 17-40L paired with the 7D? | |
For those advancing the idea that the 17-40L is a great lens on crop- even though I haven't used the combo, I'd agree!
But that's not really the question here; consider, again, that the 17-40L is slower, less sharp, and lacks IS compared to the 17-55/2.8 IS. If the OP is going FF 3-6 months down the road, the FF zoom might make sense- but if not, it really, really doesn't make sense. The 7D's sensor needs all of the speed you can give it, which the crop zoom provides with a faster aperture and IS, over the FF zoom, along with a usefully longer focal length.
So again, like Dan said above, the best advice is to buy the lens for the camera he has. Now, the newer Sigma zooms are also worthy of mention here too, but overall, Canon's fast crop zoom is the one to beat.
