I have bought another Bessa R since I posted above. And have used, this summer, my J-8, J-9(85mm), and occasionally my J-11(135mm). Good results with all of them. I don't have my FED 5 with me but will be trying out its Industar 61 L/D when I get back home. And fully expect good results from that lens, too.
I did use my collapsible I-22(50mm/f3.5) and liked the pictures but was/am too worried about collapsing it to make it a regular lens for the R.
