I find myself using the lens far more than any other because it's just the right focal length for the photos I take.
I LOVE my 70-200 f/4L IS, but I can't always use it. But when I can't use it and don't need super wide, the 30mm is perfect. In reality, you could EASILY drop the 17-55 (or sigma 17-50 2.8 os in my case) and get a UWA to accompany this in addition to a long tele (70-200) and longer if necessary.
Totally agree with you drew. I am looking at dropping my 17-50 for a uwa.
I'm thinking about the Rokinon 14mm and I would be set!
