Thanks for the replies guys, I'm learning new things after every reply
I think I definitely do need a wider lens now and am looking at the 17-40mm f/4 and 16-35mm f/2.8 II. I think both have great focal lengths on a 1.6x body but am having trouble deciding between the two. The 16-35mm is significantly more expensive...almost double the price of the 17-40 actually. But do you guys think it is worth it? Would love some opinions on these two lenses and another zoom or prime that will compliment the 17-40 or 16-35 well.
honestly i think you need to quit with the L obsession hah
(or save it for a prime or a longer zoom like a 70-200)
i really don't think the 17-40 or 16-35 are worth it
and 16-35 now is getting pretty restrictive on the long end (even the 17-40 is)
I even had a 17-40 and after very careful comparison for a week including both artifical tests and a real world shoot on a hike, as I said, I sold the L and kept the Tamron 17-50 2.8 (slightly sharper overall or at least equal, less CA on the long end, faster at f/2.8, longer reach, focused as well or better in my lucks of the draw, smaller, lighter, slightly better contrast at the edges the only thing it lost at was slightly less contrasty in the center where the 17-40L is about as rich and contrasty as any lens ever)
honestly i would way look into 15-85 IS or 17-55 IS or tamron 17-50 2.8 before the 17-40 or 16-35 on a crop camera.... more useful, sometimes less expensive, often lighter, generally as sharp
if you must have an L i'd save that for a prime or a 70-200 (or maybe if canon actually does release a new wide zoom L with the 1ds4 in a couple weeks)
