I've had the R3A for a couple of months. On my old Bessa R I enjoyed framing shots with the 35mm framelines and lower-magnification viewfinder, and when I got the R3A I was a little disappointed by the fact the 40mm framelines were so close to the edge of the finder. Since then, however, I've started to shoot with both eyes open, which is a real treat, and I've come to love the 40mm focal length, which seems so natural to me. The 35mm feels wide, and the 50mm seems tight (not that I don't like those focal lengths). The 40/1.4 Nokton is a very sharp lens that renders colours and tones very nicely, and it's a compact little lens compared with the 35/1.7. Some complain about the bokeh of this lens, but as other threads discuss, it smooths out nicely at 2.8 and smaller. Using a 50mm and a 75mm is a treat on the R3A due to the 1:1 finder and wider rangerfinder base, too.
