For sure Sony is going to bring a new generation of High Resolution sensors. And the question arises if there is a necessity of a new RAW format to handle the ever increasing amount of data. I don’t know if the following rumor from an anonymous source is correct. But this what it says:
“In order to take advantage of future image sensor dynamic range Sony will switch to a different raw format.
Current Sony cameras utilize like most digital cameras 14 bit for their raw format. Although delivering a huge advantage over the 8bit and compressed jpeg images this is not longer suitable for all future image sensors.
More and more image sensors, most noticeable in the current A7 lineup are ins some rare usage scenarios constricted.
Future image sensors featuring even higher intrinsic dynamic range and thus providing HDR like image quality in difficult lighting scenarios will require a change in raw file format.
Currently two format types are in discussion: A uncompressed 16 bit format or a compressed 21bit format”
Well, one thing is certain, many will have to buy new large and fast capacity flash cards, new computers and new hard disks to be able to work with future Sony cameras!
