- Element and group count, 0.6 m closest focus and the 62 mm filter are from Japanese Wikipedia, citing カメラ年鑑'82 p.222. No weight, length or aperture-blade count was found for the E II; the 417 g of the MC/E lens and the 440 g of the PE bracket it.
- The year is the yearbook's: カメラ年鑑'82 is the earliest dated listing found, so the lens may have been on sale in 1981. Its end came with the Zenzanon-PE 75 of the ETRSi era (1988), no date was published.
- camera-wiki's 'EII (late)' is recorded as a second variant on that page's word alone; nothing found describes the change.
How to tell them apart
- The middle 75: six elements, 62 mm filter, whole-stop clicks. The MC/E lens before it has five elements and a 58 mm thread; the PE after it has half-stop clicks and a 5-group formula (Japanese Wikipedia; camera-wiki)
- A Bronica four-claw ETR bayonet with a Seiko #0 leaf shutter inside the lens, mounting only with the shutter cocked; fits the ETR, ETR-C, ETRS, ETRC and ETRSi and nothing else. Not the Zenzanon-S 80mm f/2.8 of the 6×6 SQ
Zenzanon-E II 75mm f/2.8:
- Badged E II (sellers write EII); 62 mm filter thread where the MC and E lenses take 58 mm (Japanese Wikipedia; 1976 manual)
- Six elements in four groups against the five of the MC/E lens (カメラ年鑑'82 via Japanese Wikipedia); whole-stop aperture clicks, the half stops arriving with the PE (camera-wiki)
Zenzanon-E II 75mm f/2.8, late:
- camera-wiki lists an 'EII (late)' 75 separately from the EII without describing the difference; no source found says what changed
- Zenzanon-E II 75mm f/2.8: The first recomputation of the ETR standard lens: a sixth element, a 62 mm filter and the same 0.6 m closest focus. Japanese Wikipedia dates it by its listing in カメラ年鑑'82.
- Zenzanon-E II 75mm f/2.8, late: Listed here because camera-wiki lists it, and with nothing more than that: a cosmetic or barrel revision is the likely reading, since the only formula published for the E II is the 4-group, 6-element one.

History
The Zenzanon-E II 75mm f/2.8 is the second of the three standard lenses made for the Bronica ETR bayonet, and the one in between in every respect. The ETR’s first 75 of 1976, engraved ZENZANON MC and later Zenzanon-E, had five elements in four groups and a 58 mm filter thread; the E II kept four groups but added a sixth element and moved to the 62 mm thread the rest of the ETR primes already used, while keeping the 0.6 m closest focus. Japanese Wikipedia takes the figures from カメラ年鑑’82, the earliest dated listing found, which puts the lens on sale by 1982 and probably in 1981. camera-wiki, which calls the E II lenses the revised versions of the originals, also lists an “EII (late)” 75 without saying how it differs; no other source mentions it, and a barrel or cosmetic revision is the likely reading.
The lens works like every other ETR lens: a Seiko #0 electronically controlled between-lens shutter inside the barrel, timed by the body from 8 s to 1/500 with T, running mechanically at 1/500 when the battery fails, and mountable only when cocked. The apertures click in whole stops; the half-stop clicks that sellers advertise belong to the Zenzanon-PE of 1988, which replaced the E II as the ETRSi’s standard lens with a further recomputation to six elements in five groups.
No review of the E II as such was found, and no weight or length was published for it in the sources read. What the forums say is relative: Robert Monaghan’s Bronica ETR page collects advice to pass over the MC 75 for flare and look for the E II or PE. Dealers’ titles mix the three labels freely, so the engraving on the front ring and the filter size — 62 mm here, 58 mm on the earlier lens — are what to check.
Left open: the launch year, the weight, the blade count, what the late E II changed, and any serial-number information.
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.
