Well ... I returned the 16-35 yet again (didn't get third time lucky). This was the third copy I checked and didn't like it wide open - stopping down to f/8 or so was better but I can get the 17-40 if that was my main purpose.
Maybe I need to look elsewhere ... the 17mm TSE perhaps ... this just seems to go on forever.
+1....I wasn't happy from f2.8 to 5.6.
I rented 14mm, it's quite awesome if you shoot @ wide end.
I also tried the 14mm but it was waaay too wide for my purposes. I had tough time composing because it was difficult keeping things out with the extremely wide FOV

When it comes to gear, it is better to vote with your wallet. Bitching on online forums like a lunatic doesn't get you anywhere!
