Thanks a bunch John, that's great info.

I'll start shooting questions then: that buffer running full, does it empty itself after not taking shots for a few minutes/seconds? Or how else do you get the camera back up to speed again?

And what does 'low F is 3.5 quickly moves to 5.6' and 'Light 'sensitive with F2.8' mean? I guess I just need to know what the 'F' stands for.

With regard to the lenses I think I read that you suggest sticking with the default lens until I grow out of it. Oh, and not get a Canon L series until I know for 110% sure that the reason the picture wasn't what I needed it to was not my own fault. Check.
