While nothing to sneeze at, I agree, how much of a quality gain to you expect from the cam? I mean, considering the optics, sensor size, etc, not THAT much is lost in JPEG compression. There's a reason everyone uses JPEG instead of ,say, PNG which is open and lossless. JPEG compresses better at much lower cost cor both compression and decompression. Compressing and writing a PNG could take many seconds. Most RAW formats (except for uncompressed RAW) are compressed, if lossless. Uncompressed, an image from the camera is 15MB, that takes up to 8 seconds to write on a standard card. Again, it's not like I don't want it, I'm simply raising a few questions for discussion.
