Im an beginner at all of this HD video shooting and recently picked up a t2i and will be doing the videography for a boxing sporting event. What would be the best type of lens to use for this type of shoot. I'll be shooting up close as I will be right behind the ropes at the neutral corner. I've shot with a 10-22mm f3.5-4.5 in the past and noticed that its got a great wide angle that covers the entire ring, but when the opponents are on opposite sides of the ring, zoom is not enough to get a closer shot. Is there a wide angle lens that goes to say 50mm? Any suggestions would be greatly appreciated.
