Canon should spend time improving DR before releasing this lens :
I kinda agree with you.
But still, I want this lens right now! Or a 16-50L, or a 17-40L II.. Just whatever, as long as they finally give us an UWA-zoom with sharp razor sharp sharpness across the frame.
How hard can it be?

It feels like we've been waiting an eternity for a real "Nikon 14-24-killer", and I do think people would pay solid money for this lens. But still nothing from Canon! .. As CR-guy recently said:
"Not even a whisper".
Whay cannot Canon crack this nut? Are they just afraid to hurt the sales of the 14L and 24L?
