Some interesting information on canon eos sensors
http://lclevy.free.fr/cr2/#lossless --10.1 Sensor information for each model
https://raw.githubusercontent.com/lclevy/libcraw2/master/docs/cr2_database.txt
http://lclevy.free.fr/cr2/sensors.html (Older Data base) (I just posted my camera 5D2)

Something else about compressed raw on digic iv from http://lclevy.free.fr/cr2/#lossless
(https://ibb.co/gTxGRw)
So 5d2 and the rest of digic iv use 4 color raw components and newer digic v along with the old digic iii uses 2 color components .
would this be a issue with compressed raw on digic iv since the code would be more in turn with digic v with 2 color components
or is this a nonsense idea ?
anyways interesting , maybe this can help somebody with developing :)
