I just picked this camera up as a backup and wanted to try it out tonight. Just pulled it out of the box, got the batteries charged up and ran to the game to give it a whirl. Shot with a Canon 70-200 2.8L and no flash. I had no clue as to where to put the settings, custom functions, etc., so I asked my son who uses a 7D quite a bit and he had me put it at ISO 3200 with a manual setting of f2.8 at 1/640. As it got darker I raised the ISO up to 5000 and kept the f stop and shutter speed pretty much the same but tweeked them a few times. I was very impressed with the snaps I got and could not believe I was shooting at ISOs between 3200 and 5000. Could you image film with that ISO? The silver hallide crystals would be so thin the film would almost not exist.
