Variants & identification
| Variant | Mount | Years | Serial ranges | Production |
|---|---|---|---|---|
| Zenzanon-PG Macro 110mm f/4 (1984β2002) | Bronica GS | 1984β2002 | β | About 3,000 (camera-wiki) |
- Construction (6 elements in 4 groups), 0.66m and 72mm are from γγγγ§γγ·γ§γγ«δΈε€γ«γ‘γ© p.116 as quoted by Japanese Wikipedia, and agree with camera-wiki and Tamron Japan. Length, diameter and weight (78.5 Γ 87mm, 725g) are Tamron Japan's and camera-wiki's shared figures; F4β32 is Tamron Japan's aperture range.
- Magnification: 1:4 unaided and 1:1 with the 36mm extension tube (camera-wiki; Laidric Stevenson). The flat-field description is from Tamron USA's product page.
- Dating: announced at the 1983 launch alongside a 350mm that was never released (camera-wiki); first shown as a lens at Photokina in September 1984, so 1984 is given as its first year, with the possibility that deliveries began in 1985.
How to tell them apart
- Sold as the Macro Zenzanon-PG, the only PG lens with the Macro prefix: PG is the GS-1 designation, and the four-claw GS bayonet fits no other Bronica body (camera-wiki)
- No shutter-speed ring: the Seiko #0 shutter inside is set from the dial on the body (Tamron Japan)
- A longer helicoid than the 100mm it otherwise resembles: 78.5mm against 67.5mm on the same 87mm barrel and 72mm filter, 725g, focusing to 0.66m (Tamron Japan)
- Zenzanon-PG Macro 110mm f/4 (1984β2002): Announced with the system in 1983 but not in the launch list; camera-wiki has it shown with the 200mm and the two G teleconverters at Photokina 1984, after which it stayed in the line unchanged until June 2002. Japanese Wikipedia's figures for it come from γγγγ§γγ·γ§γγ« δΈε€γ«γ‘γ© rather than the 1984 yearbook, which fits a lens that arrived after the yearbook closed.

What reviewers say
- Laidric Stevenson, Emulsive (March 2016, updated 2021) (blog) β One of his four PG lenses, valued for 1:4 on its own and 1:1 with the 36mm tube; no verdict on its sharpness beyond his readiness to put any PG lens 'up against any Mamiya RZ lens'.
History
The close-focusing lens of the system, announced with the GS-1 in 1983 beside a 350mm that never appeared, and shown as a finished lens at Photokina in 1984 with the 200mm and the two G teleconverters. Its 6 elements in 4 groups match the standard 100mmβs count, but the helicoid is 11mm longer and runs to 0.66m, a quarter life-size, and the G-36 extension tube takes it to 1:1; Tamronβs American page describes it as flat-field. It stops down to f/32, a stop further than the normal lenses, and weighs 725g on the common 87mm barrel with a 72mm filter.
At $2,265 in 1996 and $2,567 in 2004 it cost the same as the 50mm and the 250mm, the price of the specialist lenses in the line. About 3,000 were made, by camera-wikiβs count, a fifth of the 100mmβs run. Nothing separates an early lens from a late one in the sources.
Laidric Stevenson is the only reviewer found who owns one; he bought it for the 1:4 and 1:1 figures and gives no separate verdict on it, rating the PG lenses as a group against the Mamiya RZβs. No test of it alone has been found.
