Anybody around here ever shoot dance recitals? DD4 is just starting into Ballet / Tap and has a recital in about a month. Obviously it will be indoors, and I can imagine that the lighting is going to be bad. Which means I'm going to need some faster glass than what I have. Canon 70-200 f/2.8 sound about right? I would have to rent it, as I'm in no position to purchase a $1500 (non IS) or $2300 (IS) lens right now.
