- Construction (10 elements in 10 groups), the four zoom steps, f/4.5–6.9 maximum and f/22–38 minimum in half-stop steps, 1.0 m closest focus, 52 mm filters and the 65°–42° diagonal field are Japan Camera Hunter's specification; antiquecameras.net repeats 10/10, a four-stage zoom, 1 m and 52 mm. Japanese Wikipedia gives only the name, スーパーEBCフジノンズーム55-90mmF4.5-6.9. No Fuji document was found.
- focal_length_mm and max_aperture carry the wide end; the lens reaches 90 mm at f/6.9. Equivalent field: about 34–56 mm on 35mm film (Japan Camera Hunter; antiquecameras.net); Dante Stella prints '(35mm-55mm)' beside the focal lengths and elsewhere calls 90 mm like a 50mm.
- min_aperture carries f/22, the wide-end figure of Japan Camera Hunter's 'f/22–38'; the long end closes to f/38.
- Top speed: Japan Camera Hunter prints 1/700 with an asterisk and reports seeing no faster than 1/400 on his own camera. On the 60mm cameras 1/700 is available only at f/11 and smaller (camera-wiki.org), which would reconcile the two.
- Weight, length and diameter of the lens alone: not published. The camera is 880 g without batteries and 75 mm deep switched off, 91 mm on and 111 mm at 90 mm (Japan Camera Hunter). Blade count: not given.
How to tell them apart
- The only zoom ever fitted to a Fuji fixed-lens roll-film camera: a barrel marked 55–90mm on a GA645Zi body, extending from the body when the camera is switched on and further at the long end; it cannot be removed
- Not a continuous zoom: four stops at 55, 65, 75 and 90 mm, selected by a thumb lever on the back, with the finder's LCD framelines redrawn for each
- 52 mm filter thread; a lens-cap sensor warns when the cap is on
- Focused by the camera's hybrid autofocus or an LCD distance scale; no scales on the barrel. Closest focus 1.0 m, against 0.7 m for the line's fixed-focal-length lenses
Super EBC Fujinon Zoom 55–90mm f/4.5–6.9 on the GA645Zi (1998–):
- Fixed to the GA645Zi body, champagne (titanium colour) from April 1998 or black from 1999; 52 mm filter thread
- Steps to 55, 65, 75 or 90 mm by a thumb lever on the back; the camera's data imprint records the focal length
- Super EBC Fujinon Zoom 55–90mm f/4.5–6.9 on the GA645Zi (1998–): The only version, on the only body. The two body finishes are the camera's variants; the lens is the same.

What reviewers say
- Michael Nguyen (Japan Camera Hunter) (blog) — "The lens itself though is versatile and nice, displaying thin lines with nice contrast", but "I wouldn't confuse it with an exhibition making tool"; the 1990s autofocus behind it struggles near 1 m and "expect to lose some frames".
- Svein Olav Humberset (EMULSIVE) (blog) — "The lens is sharp as a tack" and "not a fast lens"; program mode "works like a charm", but manual focus by LCD distance is impractical.
- Dante Stella (dantestella.com) (blog) — Lists the zoom among the Zi's changes and calls the camera "a much more refined camera", "the Leica of Fuji 645s"; no separate verdict on the glass.
History
The Super EBC Fujinon Zoom 55–90mm f/4.5–6.9 is the lens of the GA645Zi of April 1998, the last of Fuji’s autofocus 6×4.5 cameras and the only one with more than one focal length. It is the only zoom Fuji ever built into a roll-film camera. Japan Camera Hunter’s specification gives ten elements in ten groups, a 1.6× range covering 65° to 42° on the diagonal — about 34 to 56 mm on 35mm film — maximum apertures of f/4.5 at 55 mm and f/6.9 at 90 mm, minimums of f/22 and f/38, closest focus 1.0 m and 52 mm filters; antiquecameras.net repeats the construction, the closest focus and the filter size, and Japanese Wikipedia gives the name and aperture alone. No Fuji data sheet was found.
It is a stepped zoom rather than a continuous one. A thumb lever on the back of the camera moves the lens to 55, 65, 75 or 90 mm and nowhere between, the finder’s LCD framelines redraw for each step, and the data imprint records which was used. The barrel extends when the camera is switched on, from 75 mm to 91 mm of body depth, and to 111 mm at the long end; a sensor warns if the cap is still on. Like the line’s fixed-focal-length lenses it cannot be removed and carries no scales, being focused by the camera’s hybrid autofocus or by distances set on the rear LCD and stopped down in half-stop steps by the stepper-driven #00 leaf shutter that serves as its diaphragm. Its 1.0 m closest focus is further than the 0.7 m of the 60mm and 45mm cameras, and f/6.9 at 90 mm, in a shutter whose fastest speed in practice is 1/400, leaves little room at either end of the exposure range.
Verdicts on the glass are kinder than verdicts on the camera. Svein Olav Humberset found it “sharp as a tack” and “not a fast lens”, with program mode that “works like a charm”; Michael Nguyen calls it “versatile and nice, displaying thin lines with nice contrast”, and in the same breath says he “wouldn’t confuse it with an exhibition making tool” and that the 1990s autofocus, which struggles near the 1 m limit, will lose frames. Dante Stella, who thought the Zi “a much more refined camera” than the earlier GAs, passes no separate judgement on the zoom. The camera was about $1,849 in 1999 by Nguyen’s account, and the lens is the reason: it turned the line’s one-lens cameras into something a traveller could carry alone.
