Sure you could blow sixty grand on an Arri Alexa or $16 thousand for a Canon C300. Then again, you could just as easily get the same 4K video quality for less than $10k with Red's newest iteration of the Scarlet Cinema Camera rig.
The pocket-sized Scarlet has advanced quite a bit since its initial release. For one thing, the Scarlet now records in full 4k resolution—up from a measely 3K in 2008—that's 4096×2160 pixels for video, a stunning 5120×2700 for stills, and a maximum frqame rate of 120 per second. For reference, that's 50 megabytes of data captured every per second.
The new Scarlet wil retail for an estimated $9750 when it debuts November 17th. [TechCrunch]
