As for how the 2/3″ Scarlet will stack up against the EX1 generally, well, the EX1 is a much more credible threat in terms of sensor specs than the HVX200, but where it falls apart, I think, is with the recording format…. 35 megabit long-GOP MPEG2 vs. 366 megabit (42 MB) Redcode. Over ten times the data rate and a more modern codec. And raw sensor data rather than a processed video image.

The pixel density on a single bayer sensor means that the individual cell size will be smaller than the HVX which translates into noisier. (The cells are only 3.2 microns) It also translates into needing much better glass to realize that better resolution. You'll have to spend a few grand to get that resolution, you can't slap on any old lens on the 2/3" scarlet. Couple the scarlet with middling glass and you'll not get any better images off it than an EX1, maybe worse.</p> <p>They should have used the same cell structure as all of their other cameras, 5.4 microns, This would yield a larger sensor for even better shallower DOF, better S/N, and more forgiving of glass.</p> I’m not that impressed.

The new 16GB cards from Red are 550 dollars, 16GB P2 cards are 850 dollars. The new 32GB P2 cards from Panasonic are 1550 dollars, which isn't that far from the Red price. Of course, you get much more video duration on a P2 card than on a Red card, given the difference in compression rate.</p> <p>As for availability, well, you pretty much need to buy cards from Red, they're the only ones guaranteed to be fast enough.</p> Actually, the price of CF cards isn’t that different from the P2 prices.
