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 125mm f/5.6 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 5 groups), closest focus 0.57 m and the 82 mm filter are given by both Japanese Wikipedia (5群6枚, 0.57m, φ82) and the English Wikipedia lens table. Weight (545 g), the dimensions 101 × 107 × 80 mm and the list price ¥142,000 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.
At 545 g this is the lightest lens in English Wikipedia's table, 20 g under the 135mm f/5.6, which Danny Burk nonetheless calls 'the lightest normal lens'. The English table gives f/5.6–45 as the aperture range.

How to tell them apart (expand)

Engraved EBC FUJINON GX (or GX M) 1:5.6 125mm with an 82 mm front thread, 80 mm long on its board: the smallest and lightest lens of the line. The 125mm f/3.2 of the same system is a 95 mm-filter lens of 895 g that stops to f/32 (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 125mm f/5.6 in a Copal shutter, which has a shutter-speed ring and no GX board
Fits only the GX680 bodies (GX680, GX680II, GX680S, GX680III, GX680IIIS)

EBC Fujinon GX 125mm f/5.6:

'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 125mm f/5.6:

'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 125mm f/5.6: 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 125mm f/5.6: 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 125mm f/5.6 is the smallest lens made for the GX680, Fuji Photo Film’s 6×8 studio single-lens reflex of 1986. Six elements in five groups, 80 mm long on its board and 545 g, it is the lightest entry in English Wikipedia’s table of the line, 20 g under the 135mm f/5.6 that was sold with most bodies; on 35 mm film its angle would be a 57 mm lens. It focuses to 0.57 m, stops from f/5.6 to f/45, and takes the 82 mm filters that camera-wiki calls the system standard. The same focal length exists as the 125mm f/3.2 GX MD, a lens of eight elements, 895 g and a 95 mm thread, so a 125 on a GX680 is one of two quite different lenses. Fujifilm’s history of the Fujinon name explains why even the small GX lenses are large for their format: the revolving back meant each had to cover an 8 × 8 cm image circle 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 125mm f/5.6 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 ¥142,000, between the ¥122,000 of the 135 mm and the ¥178,000 of the f/3.2 lens of the same length, though the year of that price is not recorded. No published review of the lens was found. Danny Burk, who reviewed the GX680III in 2002 with seven lenses from 50 to 500 mm, did not own this one. Left open: the introduction date, the number of diaphragm blades, and whether the 125mm f/5.6 was among the launch lenses.
