I only delve in digital photography and digital recordings; I love taking pictures and I love to record the scene...
I have a Canon SD500 as my shooting camera, and a Canon ZR850 for my digital camera cording. I tend to run around with an SD card in my ZR850 so that I can take quick photos while recording (and it works rather well, it has a great stabilization system).
As for accessories... I tend to bring extra media (SD cards) and a few spare batteries. I also have a great Tripod that I picked up at sears, I went and purchased a digital level tripod, which yes, fits the standard camera eye hole without a problem.
I tend to over compensate for any shoot/recording, it's always good to bring too much spare equipment than to not bring enough... so 6gb or so in SD cards and 6-8 spare MiniDV tapes for a weekend work nicely for me.
