The Red One first introduced in 2007 was Red Digital Cinema’s first production camera. It captures up to 120 frames per second at 2K resolution and 60 frames per second at 4K resolution. Its "Mysterium" sensor was acquisitioned for use with the proprietary RAW format called Redcode. By 2010, Red began selling upgrades to a 14 megapixel sensor called the "M-X". The Red One has been reviewed as having effectively the same quality as 35mm film. The Red One was made out of cast iron and the body alone weighs in at 10 lbs (4.5 kg).
