Just wanted to start a thread about the Red Scarlet-X, which is a pretty amazing engineering feat for $15K or less in early 2012 compared to everything else I've used, and as near to a camera I would design from scratch on a napkin with a checklist, be it RAW, resolution, bit depth, SSD recording and unbelievable expandability.

I am damn impressed. Just have to really love features like :

PL mount, Canon mount, Nikon mount (see link below)

Redcode RAW recording ( looking at footage from years ago, color science progress is impressive)

Upgradeable 4K sensor to unspecified Dragon sensor in next year, pretty amazing design...

In a world that lately seems content to offer less tech for more money, they have shattered the mold with this product, and unbelievably now made in the USA.

There are also some frustrating cons with constant firmware rebuilds, 60p is not there at 4K, hdmi and hd-sdi scaling issues, low-light performance could be better but is acceptable considering sensor size, and reliability should hopefully improve, but once they get all the kinks out, I think this product just carved out "THE STANDARD" for what pros expect in a 4K professional cinema camera going forward...

PS: I know, it's a constant work in progress, but they have pretty much shut my mouth from complaining about much aside from being patient about firmware and reliability
