[QUOTE=sega62;13270923]Sorry Dave, you are right but I will see the players so small, my question is if I use a 100-400 is from Canon and I zoom, I will need a lot of light!!!!/quote]
You *might* get enough light out those arena lights to use the 100-400, but I highly doubt it. At f/5.6, you probably won't be able to get your shutter to 1/400 or better,, even at ISO 6400; try opening up with the lenses you do have and see what sorts of shutter speeds you can get to.
