I want to use my Sigma FE 14mm f1.4 ART on my GFX body. Don't see any adapters out there for this. Advice?
The registration distance required would put the FE lens inside the GFX mount. (Which is so big....I guess it could be theoretically possible to rig some kind of recessed adapter, but AFAIK, no one has come up with one.)
Simple answer is there isn't such an adapter and it would be hard to make one. The registration distance would create a rather large problem. You could try to stick the FE lens into the throat of the GF mount as Tim noted, but many lenses wouldn't fit as they are too wide at the bottom, or you could add glass to the adapter which would affect the images. So far nobody has done that either. I don't expect such an adapter to ever be made.
Yeah, like others have said, theres the physical limitation with the flange distance. If you are stuck with really wanting to use the Sigma 14mm 1.4 ART (for rendering or what not), the alternative is to get the canon EF version and get the Canon EF to GFX adapter.
It would have to include optics to compensate for the additional flange focal. Then the question becomes how to maintain sensor coverage. Probably not feasible or it would have been done by now.

I was looking at the Gfx and the Fringer EF-Gfx adapter. For the Sony's, the electronic contacts would actually be inboard of the Gfx body contacts. Unless the diameter of the Sony mount is enough smaller, it doesn't look physically possible even if you could machine a tricky dogleg mount for the contacts. But maybe it would be without contacts, manual only. Can't imagine a whole lot of people wanting to use their E-mounts manually on a Gfx. And it does seem that if you could get it mounted that close to the Gfx sensor that it would have coverage. Crazy how tight Sony's mount is, I can see why its suggested that it was intended as an APSC mount.
