- Year: no source dates the lens's introduction. 1986, the system's launch (Japanese Wikipedia; Fujifilm's own history), is carried as a floor: the plain GX form belongs to the generation before the December 1997 M chip. English Wikipedia says the GX680 was shown at the PMA convention with nine lenses, without naming them, so whether a 150 was among the launch lenses is not known. The end date is the system's discontinuation in April 2010 (camera-wiki), not a lens-specific date.
- Construction (6 elements in 4 groups), closest focus 0.72 m and the 82 mm filter are given by both Japanese Wikipedia (4群6枚, 0.72m, φ82) and the English Wikipedia lens table. Weight (705 g), the dimensions 101 × 107 × 91 mm and the list price ¥153,000 come from the English Wikipedia table alone, which gives no year for the price. Only the third figure is entered as length: the first two, 101 × 107 mm, are shared by most lenses of the line and describe the lens unit on its board rather than a round barrel.
- Aperture: f/4.5 makes this the only GX lens between the f/3.2 trio and the f/5.6 lenses other than the 100mm f/4; the English table gives f/4.5–45 as its range.
How to tell them apart
- Engraved EBC FUJINON GX (or GX M) 1:4.5 150mm with an 82 mm front thread; the only 150 mm lens of the system, and the only GX lens of 6 elements in 4 groups (Japanese Wikipedia; English Wikipedia)
- Mounted on its own electronic lens board with the GX bayonet, with an aperture ring and a depth-of-field preview lever on the lens and no shutter-speed ring: the Seiko leaf shutter inside is timed electronically, 8 s to 1/400 plus B, and cocks automatically (camera-wiki; English Wikipedia)
- Not the large-format Fujinon-W 150mm f/5.6 in a Copal shutter, which has a shutter-speed ring and no GX board, and not the Fujinon TS 150mm f/5.6 of the G690 rangefinders, a breech-lock lens with its own shutter and speed ring
- Fits only the GX680 bodies (GX680, GX680II, GX680S, GX680III, GX680IIIS)
EBC Fujinon GX 150mm f/4.5:
- 'GX' alone in the name: the marking of the lenses made from the GX680's launch until the M chip of December 1997 (camera-wiki; English Wikipedia's 'GX (M)')
EBC Fujinon GX M 150mm f/4.5:
- 'GX M' in the name: the M generation carries the electronic exposure counter introduced with the GX680III in December 1997, so the III displays a per-lens shot count; on a GX680 or GX680II the lens works without the counter (English Wikipedia)
- EBC Fujinon GX 150mm f/4.5: The first form of the lens, without the exposure-counter chip. No source dates its introduction; the marking places it in the 1986–1997 generation. It works on every GX680 body, the III included, which simply shows no shot count for it.
- EBC Fujinon GX M 150mm f/4.5: The lens as listed in every current lens table, with the M chip of the December 1997 generation; the system was discontinued in April 2010.

History
The EBC Fujinon GX 150mm f/4.5 is the short portrait lens of the GX680, Fuji Photo Film’s 6×8 studio single-lens reflex of 1986, a half stop faster than the f/5.6 lenses either side of it and the only GX lens of six elements in four groups; English Wikipedia’s table makes it the equivalent of a 69 mm f/2.1 on 35 mm film. It focuses to 0.72 m, stops from f/4.5 to f/45, takes the 82 mm filters that camera-wiki calls the system standard, and weighs 705 g on a board 91 mm long. Fujifilm’s history of the Fujinon name explains the weight: the revolving back meant every GX lens had to cover an 8 × 8 cm image circle, eight times the 35 mm frame, and keep covering it under the front standard’s rise, shift, tilt and swing.
Like every lens of the system it sits on an electronic lens board with the GX bayonet and carries its own Seiko leaf shutter, timed electronically from 8 s to 1/400 plus B, cocked automatically and synchronising flash at every speed; the lens has an aperture ring and a depth-of-field preview lever but no shutter-speed ring. Two markings exist. The lenses of the first generation read GX; with the GX680III of December 1997 came GX M, a chip that lets the III show a shot count for each lens, and which the GX680 and GX680II ignore, as the III ignores its absence on an older lens. No source dates the 150 itself. The plain GX form belongs to the generation before December 1997, so the 1986 given above is the system’s launch, carried as a floor rather than a documented date; English Wikipedia’s nine lenses at the GX680’s PMA showing go unnamed. The system was discontinued in April 2010.
Its list price was ¥153,000, a quarter above the 135mm f/5.6 standard lens, though the year of that price is not recorded. No published review was found; a forum owner who had both asked what the 135 offers over the 150 beyond its field of view, and the two are close enough in size that the question is fair. Danny Burk, who reviewed the GX680III in 2002 with seven lenses, did not own this one. Left open: the introduction date, the number of diaphragm blades, and whether the 150 was among the launch lenses.
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.
