Have a look for a used Sigma 15-30
You can find a good used one for about £150 and quality wise its easily comparable with the 17-40, and probably the 16-35 at the centre although drops off at the edges more
Thanks guys.
I have read some pretty poor reports on the 17-40 saying it is not up to Canon L standards.
The 16-35 has much better press but it is expensive even second hand. This will be the least used of my lenses so I am looking for something a bit less expensive.
There's many shots out there to disprove that theory. Have a look at Mark mullens images on Flickr (also a TP member) he uses a 17-40 with a 5D3 and his results are really good.
As for the 16-35 you are really paying more for the f2.8, I'd say IQ isn't much better than the 17-40. IMO obviously!
shoot at f/5.6 or f/2.8! and compare the differences!
of course by f/16 everything is evened out and getting soft due to diffraction
Sorry should have stated between f11 and f16 where most landscapers shoot with these lenses
