Great shots everyone. I love checking this thread to see how everyone is using this little gem.
It's funny, I had a little trouble with my 35mm f/2 when I first got it. Thin DoF and no IS took some adjustment on my end. Plus, my lens came from Canon with a slight front-focus problem, which was resolved by Canon's local service/repair location. Now that I've had time to use it more and compare it to the 50mm f/1.8, I really appreciate the 35mm a lot more. The sharpness at f/2 is really impressive, and the AF noise is just not an issue for me. Using it on a T1i, the focal length is just right for me shooting indoors.
I love this little lens. 
How's the focusing on it with the 5D2? Buzzy loud but fast? 50mm f/1.8-ish slow?
I find it better than the 50mm f/1.8, but not as fast and accurate as a USM (my USM experience is limited to the 15-85mm).
