The camera doesn't actually save any images on the digiFilm (it has an SD-card slot for that) but instead ISO, color and digital filter settings are controlled by inserting a digiFilm cartridges. How's that for a gimmick?
They've taken it too far, but there's a sound Idea there.
I would absolutely love a digital version of my GR1 with the same controls. Either full auto or aperture priority on a roller wheel. Fixed lens and a nice big sensor, no screen.
