- Nine elements in eight groups: Tamron USA's 2004 product page and Japanese Wikipedia (8群9枚, citing プロフェッショナル中判カメラ p.113). Closest focus 0.37 m, f/4.5–32, 72 mm filter, 107 × 86 mm and 940 g: Tamron Japan's SQ-Basic table (2001) and Tamron USA (2004) agree. Tamron USA gives the angle of view as 39.8° and the length as 107 mm with an 86 mm diameter ('86mm x 107mm'); Tamron Japan prints the same pair as 全長X最大径 107X86. The blade count is not given anywhere read.
- Years. The lens is listed from 2001, the copyright date of the Tamron Japan page (captured April 2002) that is the earliest document naming it; it is not on Tamron USA's price list of 15 April 1996, where the f/4 macro still stood, so it appeared between those dates. The end is the end of SQ production, September 2003 (camera-wiki); Tamron USA's page was still live in June 2004.
- Price: $2,159 on Tamron USA's 2004 page. No 1996 price exists for it, and no yen price was found.
- Magnification: Tamron USA says 1:1 'without bellows or extension tubes', and the same page claims no distortion at any distance and recommends it as a stand-in for the PS 80 as a normal lens — the maker's copy, not a test. Japanese Wikipedia gives only the 0.37 m.
How to tell them apart
- The later and heavier of the two 110 mm SQ macros: 1:1 on the barrel, 72 mm filters, bayonet hood, 940 g. The earlier Zenzanon-PS Macro 110mm f/4 has a 67 mm thread, is 79 mm long and weighs 685 g, and sellers mislabel each as the other
- An SQ lens: four-claw bayonet and a Seiko #0 leaf shutter in the barrel (Tamron Japan). The Zenzanon-PG Macro 110mm f/4 for the GS-1 and the Zenzanon-PE Macro 105mm f/4.5 1:1 for the ETR bodies are different lenses on mounts that do not interchange
Zenzanon-PS Macro 110mm f/4.5 1:1:
- Marked 1:1 and f/4.5; 72 mm filter thread, the only SQ lens between 65 and 250 mm that does not take 67 mm
- 107 mm long, 86 mm across, 940 g, with a bayonet hood supplied in the box (Tamron USA 2004; Tamron Japan 2001) — heavier than every other SQ prime except the 250 and the 500
- Zenzanon-PS Macro 110mm f/4.5 1:1: The only version, and the last macro lens of the SQ system: it replaced the Zenzanon-PS Macro 110mm f/4 some time between April 1996, when Tamron USA still listed the f/4, and 2001, when Tamron Japan's SQ-Basic table carried only this lens. It was in the US range until SQ production ended in September 2003 and was still on Tamron USA's site in June 2004.

History
The Zenzanon-PS Macro 110mm f/4.5 1:1 is the last macro lens Bronica made for the SQ system and the only SQ lens that reaches life size on its own. Nine elements in eight groups, it focuses from infinity to 0.37 m without tubes or bellows, stops down to f/32 in half-stop clicks, and takes 72 mm filters where the rest of the mid-range SQ lenses take 67. At 107 mm long and 940 g it is a large lens for a 110 mm, and it came with a bayonet hood rather than the screw-in S hoods of its neighbours. Tamron USA’s 2004 page lists it at $2,159.
It replaced the six-element Zenzanon-PS Macro 110mm f/4, which focused only to 0.66 m and needed the S-36 tube or the Automatic Bellows S for close work. The f/4 was still on Tamron USA’s price list in April 1996; by 2001 Tamron Japan’s lens table for the SQ-Basic showed only the f/4.5, so the change falls between those dates. It stayed in the range until SQ production ended in September 2003 and was still on Tamron USA’s site the following summer. Tamron’s copy of 2004 claimed it gave no distortion at any distance and could stand in for the PS 80 as a normal lens; that is the maker speaking, and no independent test or review of the lens has been found.
Buying one, check the front ring says 1:1 and f/4.5 and that the filter thread is 72 mm: the earlier f/4 is routinely listed as this lens and this lens as the f/4. Like every SQ lens it carries its own Seiko #0 leaf shutter and fits every SQ body, including the manual-only SQ-B, where Tamron Japan lists it by name.
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.
