Leica T (Typ 701) raw file (DNG) analysis
I just took a quick look inside a DNG from one of Leica's new Leica T cameras:
The camera firmware version number shows as "1.02", so what should be production firmware. The camera name shows as "Leica T (Typ 701)" The image data is 12-bit. There is no compression used in the DNG I looked at. Somewhat unusually, the data is appears to be packed, four 12-bit values in 6 bytes, rather than the more typical one 12-bit value in a 16-bit location. This is allowed by the DNG spec, but isn't often used. This means that the file size is approximately 24.5 MB vs. what would otherwise be approximately 33.6 MB. The DNG version is 1.3, a higher revision that that the 1.1 that most previous Leica cameras have used.
