- Six elements in four groups, 0.66 m closest focus and the 67 mm screw-in filter: Japanese Wikipedia from the 1998 Camera Nenkan (p.324), matched by camera-wiki's table; the 79 mm length and 685 g are camera-wiki's alone. The maximum magnification, the minimum aperture and the blade count are not given by any source read. Tamron USA's 2004 page for the successor says the f/4.5 lens 'provides 1:1 magnification without bellows or extension tubes', which the f/4 at 0.66 m did not; the S-18 and S-36 automatic extension tubes and the Automatic Bellows S ('1:1 & larger') were the system's way closer.
- Year. The lens is listed here from 1996, the date of the earliest document that names it (Tamron USA's SQ-Ai price list of 15 April 1996); the PS line is older than that, but no source read gives the year the PS lenses or this one appeared. It was gone by 2001: Tamron Japan's SQ-Basic page of that year lists the 110mm F4.5 MACRO [1:1] and no f/4, and Tamron USA's 2004 pages do the same.
- Price: $2,093 on Tamron USA's list of 15 April 1996 — the same figure as the PS 50mm f/3.5 and the PS 150mm f/4, above the $1,465 PS 80 and below the $2,660 PS 180.
- Shutter and aperture ring are system values from Tamron Japan's SQ-Basic specification (Seiko #0 electronically controlled, 8 s–1/500, mechanical about 1/500, half-stop clicks) and camera-wiki (T on every lens; 16 s and bulb on the SQ-Ai).
How to tell them apart
- Two Bronica macro lenses say 110 on the front ring and both are SQ lenses: this one is f/4 with a 67 mm thread; the later one is f/4.5, marked 1:1, with a 72 mm thread and a bayonet hood. Sellers routinely put f/4.5 or '1:1' in the title of an f/4 lens — read the ring and measure the thread
- The Zenzanon-PG Macro 110mm f/4 for the 6×7 GS-1 is a different lens on a different bayonet; an SQ lens has the four-claw SQ bayonet and its own Seiko #0 leaf shutter (Tamron Japan)
Zenzanon-PS Macro 110mm f/4:
- Macro lens with f/4 on the ring and a 67 mm filter thread, 79 mm long and 685 g (camera-wiki); the 1:1 lens that replaced it is f/4.5, takes 72 mm filters, is 107 mm long and weighs 940 g
- Product code BQ1265 on Tamron USA's 1996 list; hood BQ1403, the screw-in hood shared with the PS 150 and the S 105 and 150
- Zenzanon-PS Macro 110mm f/4: The only version. It is the earlier of the two PS macro lenses at 110 mm: present on Tamron USA's price list of April 1996 and in the 1998 Camera Nenkan, gone from Tamron Japan's SQ-Basic lens table of 2001 and from Tamron USA's 2004 pages, where the 110mm f/4.5 1:1 stands in its place. When exactly it was introduced and withdrawn is not recorded in any source read here.

History
The Zenzanon-PS Macro 110mm f/4 was the close-focusing lens of Bronica’s second SQ line, the Zenzanon-PS. Six elements in four groups, it focuses to 0.66 m, takes the 67 mm filters common to most SQ lenses, and weighs 685 g at 79 mm long. Like every SQ lens it holds its own Seiko #0 electronic leaf shutter, 8 seconds to 1/500 with a mechanical 1/500 in reserve, and mounts on any SQ body from the 1980 original to the SQ-B. Tamron USA listed it in April 1996 at $2,093, level with the PS 50 and the PS 150.
Its magnification on its own is not stated in any source read for this page; Bronica’s 1:1 answer for the system was the Automatic Bellows S, with the S-18 and S-36 tubes for intermediate distances. That changed when a new 110 arrived: the Zenzanon-PS 110mm f/4.5 1:1, a nine-element lens reaching life size unaided, which had taken the f/4’s place by the time Tamron Japan drew up its SQ-Basic lens table in 2001. The f/4 is in the 1998 Camera Nenkan and absent from everything later, which brackets its withdrawal between 1996 and 2001 without fixing it.
The two lenses are confused constantly in the used trade, where an f/4 is sold as an f/4.5 or as a 1:1 lens and the reverse. The front ring, the filter thread (67 against 72 mm) and the size (79 mm and 685 g against 107 mm and 940 g) settle it. No published review of the f/4 was found.
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.
