7Dmk2 saa kovaa hehkutusta Roger Clarkilta:
"A major improvement for long exposures is that the 7D Mark II camera has thermal dark current approximately 10 times lower than the nearest Canon camera I have measured as of this writing. This makes the 7DII a game changing camera"Ilmeisesti myös Canon-sensoreita pitkään vaivannut pattern noise on saatu vihdoin haltuun.
