Steve Your recollection is correct. Sorry, no fixes that I know of. We need someone to hack the firmware of Canon to make it behave in a more reasonable fashion. I resolve the issue as I described in a post a while back. If I were advising your friend, and if he does not already have an investment in a Canon system, I would say go Nikon and Leitax. But of course, he looses the ability to use his R8. Any hackers want a challenge?????
