I have been asked to do some images at a Boxing Event, A first for me , I have the D3x [Not the fastest camera} Pro Lenses. Cannot use flash, low light with different colour casts I need to be capable of catching the speed of the boxers, If anybody is familiar with this type of Photography any help would be appreciated, I appreciate shutter priority high ISO but what are the best setting for fast autofocus without tracking or hunting. I will be ringside.
Probable lenses will be 24-70 and 70-200 f2.8
