The introduction of the NEX-IFR5 interface unit is the first implementation of 2K RAW recording capability with the AXSM memory system. 2K RAW provides all the benefits of RAW - wide color gamut, full sensor latitude and flexible digital image manipulation - but at a cost efficient 2K resolution. 2K RAW enables the NEX-FS700 to create digital RGB files with 12-bit color depth, and also works simultaneously with the camera's on-board 8-bit AVC-HD capability.
