Sold an R3A to finance my M6, which is a lovely piece of work but the Bessa has some features and weight advantages that make it a better camera to carry and use. Still have the R4A as I tend to use WA a lot when travelling. All CV glass and it's quite good enough, especially at the price. FL's of 15, 21, 28, 35, 50, 75, 90. Had a 25 as well but really it's such a close fit between 21 and 28 that it was almost redundant, even though a useful length. I use accessory viewfinders on the R4A for the 75 and 90 FL's or a 21/25 VF on the M6 if going wider than 28mm.
