- Closest focus 1.2 m and the 77 mm thread are Japanese Wikipedia's figures; f/8, the Copal #0 shutter and f/45 as the minimum are from Steve Walton's lens list. No element count, weight or layout has been found. The G617's fixed 105mm is six elements in four groups by Andrew Whitehurst's specification; whether this unit shares it is unknown.
- Centre filter: Japanese Wikipedia lists the centre filter GX617 against this lens and the 90mm. Walton calls the filter mandatory only with the 90mm; Adam Ottke, who shot with the 105mm, used a centre filter he calls two stops and a reader calls one.
How to tell them apart
- SW on the ring and f/8 maximum, like the G617's lens, but removable, in a Copal #0 rather than a Seiko shutter, and focusing to 1.2 m (Japanese Wikipedia; Steve Walton)
- 77 mm thread, taking Fuji's centre filter GX617 (Japanese Wikipedia)
SW Fujinon 105mm f/8 lens unit (1993–):
- A complete module: lens, Copal #0 shutter and focusing helicoid on the GX617 bayonet, supplied with its own clip-on finder (Steve Walton; Japanese Wikipedia)
- Focusing scale to 1.2 m, where the G617's fixed 105mm stops at 3 m (Japanese Wikipedia)
- SW Fujinon 105mm f/8 lens unit (1993–): The standard unit, about a 26 mm lens in 35 mm terms (Walton), and the one both reviewers shot with. Its helicoid reaches 1.2 m against the G617's 3 m, and no source read for this page says whether the glass is the G617's six-in-four design or a new one.

What reviewers say
- Steve Walton (Emulsive) (blog) — The unit he weighed the camera with (2.43 kg together with its finder), the 26 mm-equivalent standard of a system he finds "big, heavy and idiosyncratic" and rewarding for frames with "depth and detail".
- Adam Ottke (Fstoppers) (blog) — His working lens on the GX617: f/8 wide open is "pushing it" for sharpness across the frame, so at least f/16 on a tripod, f/11 for his own project, and 1/320 or faster hand-held; "I love my Fuji GX617".
History
The SW 105mm f/8 is the standard unit of Fuji’s Panorama GX617 and the lens the camera is usually sold with: a 26 mm-equivalent on the 6×17 frame, EBC-multicoated, in a Copal #0 shutter of 1 s to 1/500 plus B with flash sync at every speed, focusing by scale to 1.2 m and stopping down to f/45 behind a 77 mm thread. It carries the same designation and aperture as the fixed lens of the G617 of 1983, but it is a different unit: removable, in a Copal rather than a Seiko shutter, and with a helicoid that reaches 1.2 m where the older camera stops at 3 m. Whether the glass inside is the G617’s six-element design or a fresh computation is not something any source read for this page says.
Both GX617 reviewers used it. Steve Walton weighed his camera with this unit and its finder at 2.43 kg and treats the centre filter as mandatory only with the 90mm, though Japanese Wikipedia lists the filter against the 105mm too and Adam Ottke used one. Ottke’s advice is practical: f/8 wide open is pushing it for sharpness across 17 cm of film, so f/16 on a tripod, f/11 at a pinch, and no slower than 1/320 hand-held. No construction, weight or production figure for the unit alone has been found.
