Same non-linear sq rt compression as used with the M8 (14 bit stored as 8
bit and then 're-inflated'  to 14 bit with negligible loss). Very different
to jpg compression for example.
I'm just shooting everything uncompressed anyway. The buffer "issue' is only
relevant if you shoot continuous sequences of 6 or 7 DNGs (at ~35MB a file).
I guess if you have that need then shooting compressed DNGs is the answer.
