http://www.sonyalpharumors.com/sr3-sony-working-on-internal-compressed-raw-set-of-codecs-for-the-fs-cameras/ Fingers crossed on this little rumour, would be a bit of a game changer, imo. An FS5 with internal raw would check a hell of alot of boxes, in a small, light package, for a great price. Any tech heads here that can work out what kind of compression levels (if any) would be needed for raw 4K on the fastest FS5 media available?
