Very good to know. There web site needs to be updated to make it clear they have them and they aren't just coming. And I am sure the huge 6 X 7 image circle is very nice on the GFX.

If I understand — and I have not been carefully following this thread — this is a tilt-shift lens adapter along the lines of the Mirex adapter that I use with Pentax MF lenses on my Canon 5DsR at times. If that is correct, this is a pretty cool idea — since the GFX provides enough space between body and alt lenses to include such an adapter.
That's how I did it with my Sony A7R setup. I had SMC Pentax 645 lenses on a Mirex P645 to Canon Tilt-Shift adapter. That was mounted to a Canon to Sony E Tilt-Shift adapter. That provided tilt independent from shift, tilt with swing, etc. Mirex also makes a P67 to Canon adapter (or you could get a P645 to Canon adapter, and use a P67 to P645 adapter). The tolerances of the Mirex adapters were good, so I wasn't worried about doubling up.
I'm not seeing a Canon to Fuji G shift adapter out there on the 'net, which is a shame because Mirex locks tilt opposite to shift; with a shift adapter, you could avoid that. On my current Fuji X-T2 rig I'm using a Canon FD 35/2.8 TS lens with a Fotodiox FD to X shift adapter. That makes for a very flexible setup.
I never tried the big P67 lenses, but I have read numerous times that the late model 55/4 is stellar. That might make a really nice lens for shifting on a Fuji GFX.

Unfortunately, the downside to the Kipon and Mirex and HCAM adapters is that due to their basic design and the pitch of the adjustment / locking racks they use, movements can only be made in fixed 1 mm increments.
I suppose this is potentially less of an issue for the GFX because of its 33x44 sensor (which means 1 mm is a smaller percentage of its long and short dimensions than it is with a 24x36 sensor) but I personally find this to be a bit crude in use.
That is true. For both the Mirex and the Kipon (which I'm currently using), I can't say it bothered me that much. It certainly didn't bother me as much as the general awkwardness of the whole design of these. They are a bit of a pain to use. However, they're small and light and not very expensive so I live with it.
Interestingly, the Fotodiox shift adapters don't suffer from this design. My Fotodiox FD-X adapter slides smoothly and isn't limited to the 1mm "chunks" of movement of the Kipon and Mirex adapters.

I have the Mirex adapter for Canon and that is not true. The adjustment is smooth and continuous.
I use it with a Pentax 80-160 zoom for a few subjects. I often find it useful for certain images in the desert, for example.

Well, it was true of the Mirex adapter I had three years ago and looking at their website, I can't see how this has changed since then.
And it is true of the two Kipon T/S adapters I presently own (which I will admit does not include the GFX adapter referenced above, although it certainly appears they all use the same adjustment mechanism and function similarly.)
It's certainly true on my kipon adapter, and it can't be any other way because the shift movement is controlled by pressing a tab that has teeth that mesh with the teeth in a piece on the adapter. You can't move it unless you press the tab and you can only move it and lock it into the space where the teeth mesh. That's why it's roughly 1mm at a time. Too bad I didn't take pictures when I took it apart yesterday. They would have shown exactly what I mean.
Mirex has different approaches for different lenses. I sold mine a year ago, but I found a picture of my P645 to Canon adapter that shows the same mechanism for shift (a notched plate where the teeth mesh with the tab on a spring).

Looking more closely at my Kipon, you are correct. I don't see that as a big issue, but then mine is shift only.
As often is the case, things such as this boil down to matters of perception / perspective.
For some, such as yourself, it's not a big deal, whereas for others, such as myself, it's annoying enough that I ultimately spent a lot more money to pursue other options to achieve similar end results, only in a much less annoying manner.

I just pulled out my Mirex and attached Pentax 80-160mm lens.
TILT is continuous and not subject to any 1 degree increments. SHIFT is subject to "click stop" adjustments if you line the shift up with the places where the little tab clicks in.
For me the primary use of this adapter is/was for tilt, so I had not paid attention to the shift adjustment.
(My main interest is focus related — e.g. tilt — since I can adjust "shift" more easily in post for my purposes. And that is a reminder to anyone concerned that 1 degree - or at least "one click" increments for shift might not be perfect, that it is pretty simple to compensate with a minor adjustment in post.)
Here are some shots from my son's karate tournament yesterday. These are all with the Minolta MD 135 f/2 and the GFX (with a Novoflex adapter). I really like this combination. They are all shot wide open in a fairly small gym with crummy fluorescent lighting.
If you're willing to make a small modification, you can have continuous shift on these kinds of adapters. The increment is determined by the meshing of the teeth on the opposing pieces. When you're pressing down on the shift indicator, you're separating the teeth. If you simply must have free shifting (i.e., not be limited to the pre-defined increments) you can file off the teeth.
I wouldn't go that far because there's value in having those increments. However, on my Kipon T/S adapter, I have found it useful to shorten the spring a bit so there's slightly less tension. This is simply to make it easier to press the shift indicator (easier on my fingers!)

Something a bit odd is going on along the ragged border between sky and roof to the left of the light bulbs. Do you see it? (Possibly just a sharpened edge that was OOF?)

It could be, but this lens on film and on a DSLR, IMO, always had pretty ugly bokeh and I think that is just the bokeh.

Last time I checked my adapter, I'm pretty sure that it IS true for shift but that it is NOT true for tilt. Tilt is continuous and not in 1mm increments.
