A good friend asked me to take pictures of his son's HS basketball game. I have a 7D and I'm planning to use my 70-200F4L but am afraid that the f4 is not fast enough. I don't think I will be allowed to use a flash. If I bump the ISO to 6400, do you think this lens is useable? Should I rent a 70-200F2.8? I can rent an 85f1.2L but it may not have enough reach.
I've never done indoor sports photography before but am actually excited to do it.
Thanks in advance for any help.
