I thought I was very ready for a good day of photography. First thing I noticed was I forgot to bring the remote trigger. No big deal. I would just use a 2-sec timer with mirror lock up. Next thing I noticed was I didn't bring the CF card. That was a show stopper - almost. Good that I also have my Olympic PEN E-P1 with me.
So what is the best camera? The best camera is the one that's with you.
