So after waiting one and a half year after my purchase of 650D, i can't see any reasonable progress towards coding its audio chip (which is also used in 700D, EOSM ETC..) . So I decided to switch to an inferior camera, the 550D for its audio features in Magic Lantern (mainly for the audio monitoring).
While I do that, I'm also planning to give RAW recording a shot. 650D has been a very problematic camera for me. It adds pink dots to the raw footage (which can be removed but requires extra steps) and it has no audio monitoring available which I need desperately.
Any info on 550D raw recording performance and resolution? I remember that 650D's SD controller can write 38MB/s maximum, I believe it differs for the 550D.
