Sony a7RIV 16 bit quantizing?
6

In a now-full thread, Joger said here :

  1. the new 62.5 MPixel sensor is 16 bit and has 15 stops DR with Sony single processing - net resolution is 60.2 MPixel at 16 bit readout
  2. The 16 bit will be calculated into 14 bit RAW files resulting in some 125 MB/image

What the heck does number 2 mean? What's the point of quantizing to 16 bit precision if you're going to round or truncate to 14 bit precision? What other methods could you use, and what would be the advantage?
