I have yet to see a FF lens on GFX that performs anywhere near the GF lenses in the corners. I think there are a couple of telephoto exceptions. I think we're better off petitioning manufacturers like Voigtlander, Samyang, TTArtisans, 7 Artisans, Tamron and Sigma to make the lenses we desire for our GFX cameras than trying to shoehorn anything wider than 50mm onto these cameras because it always ends in disappointment.
I say this as someone who was a VERY avid adapter of lenses to the Sony system, going so far as modifying my only Sony FF camera to work ideally with M-mount lenses.
EDIT: I'm also not a crazy person about corner performance, but everything I've seen both in my own and other shots is next level smeary and vignetted.
I'm still trying to understand the logic of all of this. The attraction of the GFX system is the larger sensor and the potential IQ advantages it provides, but if that's the case how is it a good thing to use lenses that compromise IQ in the corners and in some cases restrict you from using the entire frame? Doesn't that at last partially negate the value of the larger sensor?
This is why I decided to augment my GF lenses with Pentax & Contax MF lenses which are really good and can be had for some very reasonable prices. I do think that for some types of photography where central sharpness is important but corner sharpness is not 35mm FF lenses would be a good option. I've also seen some great corner to corner sharp images made with 35mm FF lenses on miniMF 44x33 sensors (I don't know how they were post processed though). Just tradeoffs in my opinion.
Using those MF lenses makes sense to me. I use one of them on a Mirex adapter on my FF system and they are pretty fine lenses in general, plus on miniMF they would have more than enough image circle.
I'm also not quite getting the appeal of having to use TS lenses to get full coverage if that comes at the expense of full use of the TS functionality.
To me, this goes to the need for Fujifilm to offer lenses that offer the functionality that users are only able to fine by adapting gear made for other cameras.
