Hello, I'm a newbie here, from Russia.
That's the great thing that you, ML, do. One can get a cinematographic camera for a fraction of a cost, not needing to get an expensive Kodak film for $100/can, to develop and scan/telecine it. All you need to start shooting in almost cinema quality is to install the ML firmware, get the quickest SD or CF card you can, and here is it. Our Russian film cameramen don't agree with me, though.
I've got a few questions and thoughts on shooting raw, the main of those is this one:
If you can get a 50D with ML, two 64 GB 1000x CF cards, a card-reader, and an external HDD connected to the notebook, then you can shoot in raw for how long you want to, for the 2 hours or so. A concert, for instance. All you have to do is to swap CF cards, copying raw files from one card to the external HDD as the second card is working in the camera. Am I right? Will the 50D overheat in a few minutes of almost continuos work?
