- Nine elements in seven groups: Japanese Wikipedia (7群9枚) and camera-wiki's table agree. The 62.3° angle of view is Tamron's.
- 0.6 m, 67 mm filter, f/4–22, 69.6 mm by 82 mm and 665 g are from Tamron Japan's SQ-Ai table; camera-wiki agrees on 69.6 mm, 0.6 m and 665 g.
- Dates. The 65 is a PS-only lens with no S predecessor in the 1982 Camera Nenkan list on Japanese Wikipedia or in camera-wiki's table. Its launch has not been dated: 1996 is the April 1996 US price list, the earliest dated document naming it. Production of the SQ-Ai and its lenses ended at the end of September 2003 (Tamron notice via camera-wiki).
- Prices are Tamron US list prices: $1,913 in April 1996 and $2,168 in 2004, between the 50 ($2,093 / $2,372) and the 80 ($1,465 / $1,660). No yen price has been found.
How to tell them apart
- Bronica SQ four-claw bayonet with the Seiko #0 leaf shutter inside the lens and no shutter-speed ring; aperture and focus rings and a T setting only
- The only SQ prime between the 50 and the 80, and PS only: ZENZANON-PS 1:4 f=65mm on the front ring, 67 mm filter
- Not the Zenzanon-PG 65mm f/4 for the GS-1 (6×7) or the Zenzanon-RF 65mm f/4 for the RF645 rangefinder, both the same focal length and aperture on mounts that do not fit an SQ; the suffix on the ring settles it
Zenzanon-PS 65mm f/4:
- Engraved ZENZANON-PS; there was never a Zenzanon-S 65, so any SQ 65 is a PS lens
- Zenzanon-PS 65mm f/4: The only version. Nine elements in seven groups, 62.3° angle of view, 67 mm filter, 0.6 m closest focus, 69.6 mm long and 82 mm across, 665 g. $1,913 in Tamron's US list of April 1996, $2,168 in 2004. The first year given is the earliest dated listing found, not the launch.

History
The Zenzanon-PS 65mm f/4 is the moderate wide-angle of the Bronica SQ, 62.3° across the 6×6 frame by Tamron’s figure, sitting between the 50 and the 80 in the range. It belongs to the second, PS, generation of SQ lenses only: the S line of 1980 ran from 40 to 50 to 80 with nothing between, and neither the 1982 Camera Nenkan list on Japanese Wikipedia nor camera-wiki’s table has a Zenzanon-S 65. It is a nine-element, seven-group design focusing to 0.6 m, with a 67 mm filter thread shared with the 80 and the longer primes, 69.6 mm long, 82 mm across and 665 g — heavier than the 50 or the 80. The Seiko #0 leaf shutter is in the lens and timed by the body, 8 s to 1/500 on the SQ, SQ-A, SQ-Am and SQ-B, 16 s to 1/500 with T and B on the SQ-Ai, with a mechanical 1/500 when the battery is flat; it mounts on every SQ body.
When it was introduced has not been fixed from a dated source. It is in Tamron’s US price list of April 1996 at $1,913 and in the 2004 list at $2,168, after production of the SQ-Ai and its lenses had ended in September 2003 and stock was being sold down. No dedicated test in English or Japanese has been found; Adrian Vila’s SQ-Ai review names the 65 among the lenses available without having used it. Left open: the launch year, a yen price and the blade count.
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.
