Originally posted by BrianR You've brought Nikon up a few times. I think you're referring to options like "14-bit Uncompressed NEF" down to "12-bit Compressed NEF" and a few variants in-between? Yes, they are modifying the raw file in most of these options. But no, it's not something anyone anywhere has a reason to complain about. Because...it's optional. You get to choose if you want to let the camera drop your raws to 12-bit or apply a lossy or lossless compression to to save space. As far as I know, their 14-bit uncompressed isn't overly manipulated (at least not in the star-eater way).
This is how major in-camera raw manipulations should be handled. User choice. If Pentax had set up their accelerator unit this way, that would be better. At the very least, we could definitely answer what the thing is doing by turning it off and seeing what changes.
No, my understanding is that Nikon cameras have 'L', 'M', 'S' options for NEF, just as they do for JPEG, but that is the least of my comments. I believe there are all kinds of things manufacturers are doing to output from sensor before it becomes a "raw" file - Fuji and Sony are probably most active in this, but I would be very surprised if anyone just transcribes from sensor to "raw" file; I don't see how any of these things reduces number of bits available, color allocation, or any of the other features people are depending on when they 'develop' "raw" file.
Ultimately, I guess we are where we were a few years ago when some people decided not to purchase K-3ii because they didn't want the change in features. If enough people make that decision, then maybe next FF camera, in another three or four years, won't have that feature.
