So, in order - bubffm, thanks. From your description, you are right, it must have been the Rx100, it was a very small camera. I will also try checking the metadata to verify.
Trickster and Nick Hope, thanks, that's exactly the kind of advice that I was looking for. I mostly shoot "run and gun" style, as Nick suggests (although I'd love to try some tripod mounted filming in the future).
I think that you folks have saved me some money this winter, but look out next year. I've got a couple of good trips planned for next year already, so I'll wait until after I get back and see what the market looks like at about this time next year. That will also give me some time to save up for the hit that my wallet will take.
Thanks again, what a great source of information Wetpixel is!
