After 4 games with the flash popping I felt the need to shoot without it. Decent light at Cal HS. ISO 1600 2.8 1/250th-1/400th. Shooting with MK2s in those conditions doesn't net the greatest results but it was nice to let the shutter fly. Action shot with the 400 2.8 non and post game with 16-35.
Nice exposure on the group photo. You stated that the 580 master was on camera and the 550 slave was off camera. Exactly where did you have the slave mounted? Did you mount it on a stand?
