Hi everyone. I received the Canon 10-22 today. It arrived a lot faster than I expected. My initial reactions once I opened the box.... Wow! This is is small. The lens is probably the lightest and smallest lens I own. It does not feel cheap. Im so glad it small and light. The thing is W I D E. The widest I have ever used is the 17mm on the 17-55. I thought to myself just before receiving it, maybe 17mm is wide enough. Yeah right. The focus ring is a lot smoother than the one on my 17-55. The lens goes on tight when I put it on the camera. The build is what I expected from an EF-S. Its good. Not too shabby. Im impressed with the lens. I will be going out again to shoot with it later today.
