I took these pictures during rehearsal last night, partly because I wanted to test out a new lens I'd bought. It's a Canon fixed 50mm, f1.8 and I'm very glad I bought it. I was able to take these shots at 1/50th to 1/90th of a second in available light, and when I tried switching back to my 28-105mm zoom lens I got readings of between 1/5th and 1/20th of second, which is unsuitable for handheld shooting. The only trouble came when I needed to take flash pictures of a group larger than three or four people; I had to stand so far back with the fixed 50mm view that the flash didn't reach them properly and the shot was quite dark. But for available light, the "nifty fifty" is a winner. And it's only around $70-$80.
