Used the 24-70mm/2.8
Lighting was "OK",
Stage was about 4 feet off the main floor, I shot accross the room (about 25feet away) on the 2nd level so I could shoot level with the fighters. Probably should have used the 70-300mm/4.5 for the reach, as I prefer waist up shots durring the weigh in.
Everyone else shoot upwards at the fighters from the bottom level.
