- Weight: camera-wiki gives 1840 g with the AE 100mm f/3.5 and no body-only figure, so weight_g is left empty. Lallement says the GM670 weighs the same as the GL690, which his table has at 1,148 g, and Eckman's 1172 g for a GL690 body would apply equally.
- Prices: camera-wiki's ¥147,800 for the body with the AE 100mm is ¥94,400 above its ¥53,400 body price, more than the ¥83,000 it gives for the lens alone; the figures are reported as found.
- Release: Japanese Wikipedia dates both the GL690 and the GM670 to November 1973; Lallement has the GM670 in January 1974 and camera-wiki simply 1974. Japanese Wikipedia's date is carried because the body is the same casting as the GL690's.
How to tell them apart
- 'GM670' in the top-plate engraving; everything else as the GL690: white 'G' on the mount, second release on the front plate, round eyepiece, mushroom lugs
- Finder frames in 6×7 proportion and a counter running to 10 on 120 — the quickest check on a body offered as a GL690
- Lens-release tab interlocked with the dark curtain; the curtain is worked from the base
- Not to be confused with the later fixed-lens GW670II and GW670III, which have no mount at all
Fujica GM670 Professional (1973–78):
- 'Fujica GM670 Professional' on the top plate; otherwise the GL690's body with the white 'G' on the mount, the second front release, the round eyepiece and the mushroom lugs
- 6×7 film gate, and 6×7-proportioned brightlines in the finder (Lallement: the GL690 and GM670 differ only in picture size, viewfinder frames and film winding)
- Counter dial for 20, 10 and 5 exposures instead of the GL690's 16, 8 and 4
- Fujica GM670 Professional (1973–78): The 6×7 twin of the GL690: Japanese Wikipedia's one line on it is フジカGL690プロフェッショナルの 6×7cm判版, and camera-wiki describes the same body with a smaller gate and different advance gearing. Body ¥53,400; ¥147,800 with the EBC Fujinon AE 100mm f/3.5, which was its standard lens (camera-wiki). 1840 g with the AE 100mm.
Serial-range notes
- No published scheme
- No source consulted ties serial numbers to years or gives a production total; the number is on a plate at the lower left of the back, as on the GL690 (Eckman).

No source gives finder figures for the GM670 itself. Lallement states that it is the GL690 except for picture size, viewfinder frames and winding, so the GL690's 67mm base, 0.75× and 50.3mm effective base are carried here (see derived). Round eyepiece threaded for dioptre lenses and a right-angle finder. The 50mm, 65mm and 180mm lenses are composed through accessory finders made for 6×9; on the 6×7 gate the 50mm covers rather less than the 90°-plus it gives on a G690 (Lallement).
Figures we worked out rather than found: The finder base length, magnification and effective base are the GL690's figures (Lallement's table for the G690 line), carried on Lallement's statement that the GM670 differs from the GL690 only in picture size, finder frames and winding. · The dimensions are not published separately; Lallement says the two bodies are the same size, so the GL690's 183 × 166 × 145mm with the normal lens applies.
What reviewers say
- Sébastien Lallement, lallement.com (blog) — "Essentially the same camera" as the GL690 — same weight, size and lenses, differing only in picture size, finder frames and winding — and the one he finds less attractive, since he prefers the 6×9 shape for landscapes and notes that a 43mm lens would be needed on 6×7 to match the 50mm's view on 6×9.
History
The GM670 Professional is the GL690 with a 6×7 gate. Japanese Wikipedia’s product list dispatches it in one line as the 6×7cm version of the GL690 Professional, released in the same month, November 1973; Lallement dates it to January 1974 and describes it as “essentially the same camera”, with the same weight, size and lenses, differing only in picture size, finder frames and film-winding mechanism. The gate gives 56×69mm, ten frames on 120 and twenty on 220 instead of eight and sixteen, and five on the short roll that the GL690 takes four of; camera-wiki adds that the advance gearing and numbering were changed to suit. Everything else is the GL690’s: the second shutter release on the front plate, the round threaded eyepiece, the mushroom strap lugs, the white ‘G’ on the breech-lock mount, and the cloth dark curtain that must be closed before a lens comes off.
Fuji sold it as a set with the EBC Fujinon AE 100mm f/3.5, the lens whose electronic Seiko shutter and CdS cell give the body an aperture-priority automatic exposure it has no meter of its own to provide; the body alone was ¥53,400 and the set ¥147,800, and the pair weighs 1840 g (camera-wiki). All seven G-mount lenses fit, though the 50mm, 65mm and 180mm are composed through accessory finders drawn for 6×9, and on the smaller gate the 50mm covers less than the 90°-plus it gives on a G690; Lallement reckons a 43mm would be needed on 6×7 to match it, and that is one reason he finds the GM670 the less attractive of the pair, the other being that he likes the 6×9 shape for landscapes.
No source gives the GM670 its own finder figures, so the GL690’s 67mm base, 0.75× magnification and 50.3mm effective base are carried here on Lallement’s word that the bodies are otherwise identical. The faults to check are the series’ usual ones: the curtain spring that loosens with heavy use, and the film advance, for which no parts exist. Production ended with the GL690’s in November 1978, when the fixed-lens GW690 replaced both; the fixed-lens 6×7 bodies that came later carry the GW670 name, and a body offered as a “GW670” or “GM670” should be checked for the lens mount before anything else.
