And this is with the 1950 "5005" series Nikkor 5cm F1.4 using an S-Mount adapter on the Bessa R2. The optics are a little different from those that followed, the change occurred early on.
After looking at a couple of rolls with it, The OOF strike me as being a bit smoother than the later 5cm f1.4 Sonnar formula Nikkors.
