Just got another copy of the 17-40. Sold a good used 16-35mkI. The 17-40 is a UV11xx, my newest lens, fresh from the factory
anyways, the 17-40 is sharper than my 16-35 was and the distortion seems much better. I am very impressed. The last two new lenses I've bought have been very high quality and I'm starting to think that buying used (for me) might not be the bargain I thought it was. Quality control at Canon, despite speckled contrary reports is high and I am definately not having any buyers remorse.
I'm sure if I would have bought the 16-35mkII I'd have been even happier but for a guy like me who shoots UW on a very limited basis (mostly landscapes, where f4 is not an issue), this lens makes perfect sense.
At 1/2 the price of the 16-35mkII I'd say it is a very sweet "bargain" L. I'm at work now but later this evening I will try to post some examples of the two ultrawides side by side.
