@cozmo2312, i see in your signature that you also own the 16-35 2.8L.. how does it compare to the 14 in terms of sharpness, contrast, color?
honestly I'm not sure. i JUST got the 16-35. the Rok is so cheap that i'm just going to keep it. that shot above is my sharpest shot out of the lens, so it is sharp, my problem is getting the focus dialed in. i've gotten a lot of soft shots purely because of user error, by no fault of the lens. i just needed something wide with autofocus so if i don't have time to setup for the shot i won't miss it.
i also got the 16-35 to replace the 35/1.4 i had. carry one lens instead of two.
