My 1DMKII is off at Canon getting a shutter replacement so I asked CPS to send me a camera just in case it isn't back in time for an air show next weekend. They were out of 1DMKIV, but had a 7D (oh yeah, and a 300 f/2.8 IS ). It is due to arrive on Friday the 15th, and I'm leaving Saturday the 16th for Atlanta so I will not have much time to mess around with it. I'll probably download the manual and skim through it, but also thought I would ask for some tips on settings. The newer cameras are far different from the MKII and 30D I currently use.
