Since I've been shooting lossless raw forever, I was also wondering about the compressed vs uncompress files in the Sony and their lack of Lossless flavors. Lossy means that image data is lost when the image is compressed while a lossless format retains all the original data, even when compressed. Many works have been done in lossless compression. Most popular freeware audio editors and shareware recorders for your PC computer, Mac OS, Microsoft XP, Vista, Windows7 etc. If an image has few colors, a file type can be designed to exploit this as a way of reducing file size. Most camera raw image files (not RAW, since it's not an extension or a standard) are compressed, and have been for many years now. PCM audio recordings are raw digital audio samples.
