@Luigi_xp -- I appreciate your input. I have owned and operated a Canon 5D for a while now, and have desperately tried to squeeze every last bit of data out of it that was possible. I agree that the difference between uncompressed and compressed is marginal, which is what led me to enquire about the possibility of recording RAW out from HDMI.
@reddeercity -- You say not possible... and never. Would you please explain why?
