Nikkor-P 1:4 f=200mm for Bronica 6x6
In 1969 the original 200mm lens was replaced with a new model. It can be distinguished from the old version by the all-metal hood with a knurled grip near the base, and the smaller front element.
- Early lenses marked "Nippon Kogaku Japan". The hood has a chrome "button" which contains a spring loaded ball bearing. The ball clicks into a groove in the upper barrel, locking the hood in extended position.
- Marking later changed to "Nikon".
- Late series with multi-coating marked "NIKKOR-PĚC". The hood no longer has the knurled grip or hood button.
