- Construction (5e/5g), filter (67 mm) and the MC marking are from Sam Seiden's lens list as reproduced by Robert Monaghan; camera-wiki gives only the name. No source gives closest focus, weight, minimum aperture, maker, years or price.
- Status: unconfirmed. Japanese Wikipedia (5群6枚) and English Wikipedia (5e/5g, 640 g) list a single 200 mm Zenzanon, at f/3.5, and name no f/4. Seiden's figures for the f/4 are identical to those of the Nikkor-P 200mm f/4 (5e/5g, 67 mm) on the same mount. The year shown is from Monaghan's history, which places a Zenzanon 200mm f/4 among the lenses available from 1966 on; it is not a documented date.
How to tell them apart
- If the lens exists as described, its plate reads ZENZANON MC 1:4 f=200mm; a Bronica 200 reading 1:4 without the Zenzanon name is the Nikkor-P, and one reading 1:3.5 is the Zenzanon MC 200mm f/3.5
- No shutter, an open rear with the small bayonet and 57 mm thread, 67 mm filter; it would fit the Z/D, S, C, C2, S2, S2A, EC, EC-TL and EC-TL II through the body's focusing mount
- The leaf-shutter Zenzanon 200s of the ETR, SQ and GS-1 are all f/4.5 and carry those systems' bayonets
Zenzanon MC 1:4 f=200mm, small bayonet:
- Listed by Sam Seiden as ZENZANON MC 1:4 f=200mm, 5 elements in 5 groups, 67 mm filter; no photograph or further description has been found
- Zenzanon MC 1:4 f=200mm, small bayonet: Known only from Sam Seiden's lens list and Robert Monaghan's 1966-on lens history, both on Monaghan's page, and from camera-wiki's one-line entry '200mm f4 Auto-Zenzanon'. It is absent from the lens tables of both Japanese and English Wikipedia, which list the 200 mm Zenzanon only as f/3.5, and no catalogue, price or dated example has been found. It may be a confusion with the Zenzanon MC 200mm f/3.5 or with the Nikkor-P 200mm f/4, whose 5e/5g construction and 67 mm filter it matches exactly.

History
A Zenzanon MC 200mm f/4 for the focal-plane Bronicas appears in two places: Sam Seiden’s lens list, reproduced on Robert Monaghan’s Bronica pages, which gives it as ZENZANON MC 1:4 f=200mm with five elements in five groups and a 67 mm filter, and camera-wiki’s list of Zenzanon lenses, which names a “200mm f4 Auto-Zenzanon” beside the 200mm f/3.5. Monaghan’s history of the lenses available from 1966 on includes it as well. That is the whole of the evidence. The lens tables of Japanese and English Wikipedia know only one 200 mm Zenzanon, the f/3.5, and no catalogue, price list, dated example or photograph of an f/4 has been found.
The figures Seiden gives match the Nikkor-P 200mm f/4 on the same mount exactly, five elements in five groups and a 67 mm filter, which leaves open whether the entry records a real Zenzanon-branded lens, a Nikkor misfiled under the house name, or a slip for the f/3.5. The page is kept because two independent lists name it, with its status marked unconfirmed; a photograph of a plate reading ZENZANON MC 1:4 f=200mm would settle it. If it exists it is a small-bayonet lens without shutter or helicoid, fitting every focal-plane Bronica from the Z/D to the EC-TL II and focusing through the body’s mount like the Nikkor.
This history is AI-written, from the sources listed at the foot of the page. Where the record is silent it says so rather than filling the gap — but no human wrote these sentences.
