SWD Fujinon 90mm f/5.6 lens unit (1993–)	Fuji GX617	1993	—	—

Closest focus 2 m and the 77 mm thread are Japanese Wikipedia's figures; f/5.6, the Copal #0 shutter and f/45 as the minimum are from Steve Walton's lens list on Emulsive. No element count, weight or layout has been found in any source read for this page.
Centre filter: Walton gives a 77 mm, one-stop centre-graduated ND, mandatory with this lens; Adam Ottke calls the GX617 filter two stops and a reader corrects him to one. Japanese Wikipedia names it 'センターフィルターGX617' and says it evens the light to the edges.

How to tell them apart (expand)

SWD on the ring, Fuji's prefix for its widest Fujinons; 77 mm thread; focusing scale to 2 m (Japanese Wikipedia)
The only GX617 unit a seller will usually offer with the centre filter attached, since it is unusable without one (Steve Walton)

SWD Fujinon 90mm f/5.6 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)
Fuji's 77 mm centre filter GX617 is mandatory with it (Steve Walton)

SWD Fujinon 90mm f/5.6 lens unit (1993–): The widest of the four GX617 units, about a 20 mm lens in 35 mm terms (Walton). Its edge fall-off is such that Walton calls the centre filter mandatory; Japanese Wikipedia lists the filter against this lens and the 105mm. No production figure or end date has been found.

What reviewers say

Steve Walton (Emulsive) (blog) — The 20 mm-equivalent of the system, which he will not use without the 77 mm one-stop centre filter; part of a camera he calls "big, heavy and idiosyncratic" and rewarding for frames with "depth and detail".

History

The SWD 90mm f/5.6 is the wide-angle unit of Fuji’s Panorama GX617, the interchangeable-lens 6×17 camera of December 1993. Like the other three units it is a complete module, EBC-multicoated glass in a Copal #0 shutter with its own focusing helicoid, which bayonets onto the body and comes with its own optical finder. On the 17 cm frame it covers about what a 20 mm lens covers on 35 mm film, focuses by scale to 2 m, stops down to f/45 and takes 77 mm filters, and its shutter runs from 1 s to 1/500 plus B with flash sync at every speed.

A lens this wide on a frame this long cannot light its ends evenly, and Fuji’s 77 mm centre-graduated ND filter is part of the lens in practice. Steve Walton calls it mandatory with the 90mm; Japanese Wikipedia lists it against this unit and the 105mm, and the dealer listing named in the packet gives it as ND-2×, which is one stop. Adam Ottke’s two-stop figure for the same filter was corrected by one of his readers.

Nothing has been found on the lens’s construction, weight or production, and no review treats the 90mm on its own; Walton’s is the one account, and the specification above rests largely on it and Japanese Wikipedia’s lens table.
