Sony unveiled its new F65 CineAlta digital motion picture camera at an NAB press conference in Las Vegas this week. The F65 camera features a 20.4 megapixel, Super 35mm CMOS sensor, a significant jump from the F35’s 12.4 megapixel 1080p CCD. Is this another step away from film as a motion picture medium?

Pictured on the left is Curtis Clark (ASC) who directed a 4K short with the new camera, that is being shown at NAB.

According to Engadget: “…this sensor is fast — not only can it capture up to 72fps on 4K, but it can also crank up to a smooth 120fps on 2K. As for those seeking to squeeze out every bit of detail from their clips, don’t worry: the F65’s got you covered with a 16-bit RAW output (19Gbps) at 4K resolution, or it can be compressed to 5Gbps for the convenience of recording onto the new SR-R4 portable 4K recorder. Looks like Sony’s finally found a candidate that’ll put a lid on film stock, but then again, at the end of the day it’ll depend on the price tag when it comes out in Q3 this year.”

Sony also announced 2 new professional 3D cameras at NAB (and for consumers, the company announced the 3D Handycam and 3D Bloggie cameras at January’s CES).
