The 80/2 with the fringer focuses accurately MORE often than the Fugi 80/1.7, something that surprised me.. The CZ/fringer is now my only 80mm lens, and it's a tad lighter than the F80/1.7, too.
Would like to see some shots at f2. I only have 80mm f1.7 but in the few shoots that I have done, I had 0 problems with it nailing AF at f1.7. All these shoots were outside though. I haven't tried that lens yet in the studio.
Can you use Sony FE lenses on GFX? if yes, which ones perform well? I would be okay with manual focus. Maybe it wouldn't work because focus by wire? I have a large number of FE Voigtlander lenses so maybe those would work better.

Simple answer is that you can't use Sony FE lenses on Fuji GFX.

GENERALLY, mirrorless FF lenses can't be adapted to other mirrorless systems because the sensor-to-flange distances are too similar, hence not enough room for the adapter.. That said, I expect there are some FF mirrorless lenses that can be adapted to GF-mount with dumbadapters.

No, all the FF mirrorless systems have a shorter registration distance than the GFX. Here are the registration distances for the FF 35mm mounts:
Nikon Z mount - 16mm
Sony FE mount - 18mm
Canon RF mount - 20mm
Leica L mount - 20mm
Fuji GF mount - 26.7 mm
Because the Fuji mount has a longer registration distance (the distance from the mount to the sensor) than any of the FF mirrorless mounts you can't easily adapt those lenses to the Fuji GFX cameras because they would be mounted too far from the sensor and it would be like permanently shooting with an extension tube. That is at least how it would work with a dumb adapter. You could only get focus to a few meters from the camera. On top of that most of the mirrorless mounts have lenses with focus by wire that would prevent focus with a dumb adapter (i.e., they need power to focus). It would be possible to make an adapter with glass and that would compensate for the longer flange difference on the Fuji and that uses the electrical contacts of the lenses to focus, but no one has done that yet to my knowledge and I think the prospects of someone doing that is low.
On the flip side you can shoot Sony FE mount lenses on a Nikon Z camera with both a dumb adapter (many cheap ones are available and one that allows AF (the Techart FTZ). I have done it myself. The AF isn't great shakes, but it is possible. I expect in time there will be Canon RF to Nikon Z adapters and perhaps even Leica L mount to Nikon Z mount adapter. Note Nikon Z has the shortest registration distance and the widest diameter, so adapting to this mount is the easiest. Adapting Canon RF and Leica L to Sony FE might be possible but the Sony mount is narrower than the Canon RF or Leica L mount so that and only 2mm shorter registration distance would make those adapters really hard to make.
does adapting canon EF lens via ef-gfx adapter will deagrease amount of light ? and does canon ef lens 40mm shows 40mm view angle or will be 32mm on gfx sensor?

There's no light loss. The adapter places the lens at the identical distance from the film or sensor that it was on the original camera, whatever brand that was, making up for the difference in register distances. A 40mm lens adapted looks just like any other 40mm lens on the Fuji camera, but its equivalent focal length to 35mm will indeed be in the neighborhood of 31mm or so when you are shooting with the full Fuji sensor and not shooting in 35mm cropped mode.

There is no light loss if the lens covers the whole GFXsensor. Very few Canon EF lenses do. The TSE lenses all do. Most of the longer primes do. Many zooms cover the full sensor for part of their range, and some lenses cover at some focus distances and not others. The vast majority of lenses, however, do not cover the full 44 X 33 mm sensor in the GFX. I know of no prime at 40mm that covers the whole sensor well, but that is partly a subjective evaluation. IMO, you will need to crop with a 40mm lens (although there is a 45mm TSE that does not need to be cropped). What focal length it will look like on FF 35mm depends on what aspect ratio you choose. If you want a 4 X 3 aspect ratio (the native aspect ratio on the Fuji, which means cropping the FF 35mm shot) then 40mm is equivalent to a 29mm FOV on FF 35mm. If you want a 2 X 3 aspect ratio (the native aspect ratio on FF 35mm, which means you will be cropping the Fuji shot), then 40mm is equivalent to a 33mm FOV on FF 35mm. If you don't crop either shot the photos won't look alike so I don't think talking about equivalent FOV makes much sense.
In practice, however, lenses are almost never a precise 40mm and often vary a fair bit and even the same lens often varies at different focus distances (this is call focus breathing). So keep in mind the numbers above are rough guidelines and won't be precise across lenses or even with the same lens across focus distances.
The Canon 35mm f/1.4 L II lens covers the full GFX format quite well, autofocuses nicely and is still very sharp. The one that surprised me the most was that the Canon 11-24mm f/4 lens stops vignetting at 14mm and is very good from 14mm to 24mm on the full Fuji frame. And, not in the sub 40mm category, while the 70-200 2.8 is not very usable do to heavy vignetting, it's little brother, the 70-200 f/4IS is very usable over much of the zoom range with only minor vignetting at certain focal lengths. That one was a nice surprise.

Here is where the subjective evaluation part kicks in. Personally, I find the outer zone with the Canon 35 f/1.4L II way too funky with lots of field curvature and astigmatism from the shots I have seen. IMO, (and it is just my opinion) it does not adapt well, but of course YMMV. Some people like the 11-24 from 14-24 as you say but I see way too much field curvature when used that way and that can be quite problematic for some typical ultra wide uses (e.g., landscapes and architecture). Finally, the 70-200 f/4 IS in my view needs to be compared to the Fuji 100-200 f/5.6. That is one of Fuji's weaker lenses, so it might make sense, but I haven't see the actual comparison. So personally, I would not be interested in the Canon 35L II or the the 11-24, but might be interested in the 70-200 f/4L, but that is just me.

Vignetting in GFX mode depends on the lens. Some lens it will be black in the corners, so yeah heavy vignetting. Other lenses it will be heavy but fairly correctable in post, and a few lenses it won't be that heavy. Vignetting in 35mm crop mode will be roughly the same as on a FF 35mm camera. For a lot of lenses that means fairly low vignetting, but of course almost all FF 35mm lenses have some vignetting on FF 35mm, so they will have similar vignetting in 35mm crop mode on the GFX.

For lenses on which the Fringer adapter is "optimized" you have to choose between the lens's IS and the camera body's IBIS. You can use one or the other but not both together.

Nope as far as I know as I don't shoot jpeg. This is also an issue when shooting RAWs as Fuji lenses have correction info for the raw processors, not for the adapted lenses.

This should be easy enough for you to test for yourself. Do it and report back.
