All these camera companies have their own variations on raw files, be they PEFs or NEFs or whatever. When Adobe released the DNG format, I thought the idea was that it would be the file format version of film: IE: a cross platform format. So what do the camera makers do? They bugger up the implementation of it. It's kinda stupid, since Adobe has already done the legwork on compressed DNG files and all the camera companies have to do is insert Adobe's compression code into their own software (it was released as open source, was it not?).
