Default Re: Leica R to Canon Autofocus question

I had a Haoda focus-confirm adapter with a 50 Summicron on a 5D. I believe it is considered a leading brand. But it would not confirm at apertures smaller that 5.6. I'm not sure if this is true generally, but Haoda acknowledged that was correct for their adapter.
