Just out of curiosity, as most of you are waiting for a new 35L, what is your complain with this lens or expectation for the new one?
I reckon it would be weather sealing and sharper corners wide open, right?
I've bought it a few months ago, and it's my favourite on my 5D2. Super sharp wide open in the centre (where it matters to me when shooting portraits), and sharp across the whole frame over f/4-5.6 (where it matters to me when shooting other stuff). Love its size and weight too (although it seems big for a prime lens).
Very nice lens. I would buy it now again (and would not wait for the mkII). The way Canon are pricing their new releases, I reckon it will cost over 2K for the new 35L
