my r3a is the same tyge, as was my bessa T and my Bessa R - but I understand (perhaps erroneously) that as RF focusing is SO accurate, what you are focussing on isn't actually infinity because we cant see as far as infinity (!) ... you are focusing on something that is x metres away from you, but not infinity - if your shooting style allows, it might be better to use the hyperfocal markings when you want focus to go to infinity, that's what I do anyway.
