This lens should be arriving any day now. I have never owned a fast prime before and I am really excited to play around with it and see what it can do. I spent a lot of time researching what the first lens (after the 12-60mm kit lens) I should purchase would be.

This review by David Thorpe really helped me decide that this was the right lens for the money.
