- Construction (16 elements in 13 groups), 1.0 m closest focus, 95 mm filter and the Tamron design credit are from Japanese Wikipedia's ゼンザブロニカ lens table; Tamron's own Bronica pages give the same construction and add the internal focus and zoom, the built-in retractable hood and 1:4.9 at 220mm.
- Weight is left absent: Tamron Japan's ETRSi data page gives 2,175 g and Tamron USA's product page gives 1,940 g, and nothing consulted settles which is right. Neither reads as a misprint, so no figure is preferred.
- No release date was found. The design credit to Tamron is carried in the 1998 Camera Annual (カメラ年鑑'98), so 1998 is the earliest year the lens can be placed with a source, not a launch date, and the page carries the single-source flag for it. 2004 as the last year follows camera-wiki.org's ETRSi production table.
- US$2,745 is the list price on Tamron USA's product page as archived in 2004, the last year of ETR production, not a launch price. No yen list price was found.
- The shutter is the Seiko #0 electronically timed leaf shutter common to every ETR lens: 8 s to 1/500 plus T, B on the ETRSi, mechanical 1/500 without battery, speed set on the body (camera-wiki.org for the body's shutter range; Japanese Wikipedia for the lens-shutter arrangement).
How to tell them apart
- Zenzanon-PE Aspherical IF on the ring: the only ETR lens marked IF, and a constant f/4.8 that no other ETR lens has
- Fixed-length barrel with a built-in sliding hood and a 95 mm front; about 2 kg²
- Closest focus 1.0 m throughout, 1:4.9 at 220mm
Zenzanon-PE Aspherical IF 100–220mm f/4.8:
- Name ring reads ZENZANON-PE 1:4.8 f=100-220mm ASPHERICAL IF; the only version, and the only ETR lens marked IF
- Internal focus and internal zoom: the barrel does not change length and the front does not rotate; a retractable hood is built in
- 95 mm front thread, shared with the PE 45–90 and the E 500mm
- Zenzanon-PE Aspherical IF 100–220mm f/4.8: The single version. Japanese Wikipedia credits the design to Tamron, and the 1998 Camera Annual lists it with that credit; no release date was found. Tamron's Bronica pages carried it to the end of ETR production in 2004 at US$2,745 list.

History
The 100–220mm f/4.8 is the telephoto zoom of the late ETR system, a Tamron design by Japanese Wikipedia and the 1998 Camera Annual, and the companion of the 45–90 Aspherical that reached the market in December 1997. Tamron’s page for it claimed the first internal-focus, internal-zoom lens for medium format: the barrel stays one length through the zoom and focus travel, the front does not rotate, and a retractable hood is built in. The construction is 16 elements in 13 groups with aspherical surfaces, the aperture a constant f/4.8, closest focus 1.0 m throughout for 1:4.9 at 220mm, and the filter thread 95 mm, shared with the 45–90. Like every ETR lens it carries its own Seiko #0 electronic leaf shutter, timed by the body from 8 seconds to 1/500 plus T, B on the ETRSi, with a mechanical 1/500 for a flat battery.
Its weight is the one number the sources will not agree on: Tamron Japan prints 2,175 g and Tamron USA 1,940 g, and with nothing to decide between them the page leaves the field empty; either way it is the heaviest lens in the ETR line after the 500mm. No release date was found, so 1998 stands as the earliest year it can be placed with a source. Tamron, which absorbed Bronica in July 1998, kept it in the catalogue to the end of ETR production in 2004, when the US list price was $2,745, the dearest lens on Tamron’s ETRSi page apart from the 500mm.
With the 45–90 it replaced the two Schneider-built Variogons of the E years; between the pair the ETR had a wide-to-normal and a normal-to-long zoom of Bronica’s own design for the first time. No published review was found, so the page says nothing about its drawing. On the camera the fixed length and non-rotating front make it the easiest ETR zoom to use with a polariser and the built-in hood saves hunting for a 95 mm accessory. A buyer should check that the hood slides freely, that the internal zoom group moves without play, that the shutter fires at the slow speeds on a body with a fresh battery, and that the lens arrives cocked.
Open points: the release date, the weight, the minimum aperture and blade count, length and diameter, a yen list price, and any review.
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.
