I love my new prime lenses! With a Canon Rebel XSi in a school gymnasium, I could never gather enough light nor use a low enough f-stop (f/1.8 in this case) to get a good photo without a good lens. I took this photo during the 8th grade band performance. The percussionists in the back row struck me as very interesting, with their varying poses and expressions; and with the narrow f-stop, they could be in perfect focus while the rest of the band was not. To emphasize the effect, I cropped the photo into a long, narrow "panorama"; I really like the effect.
