I am using the fringer as well as the photodiox fusion. I am shooting in medium format mode, not 35mm and have nothing close to what des-1 has shooting wide open. Someone posted a link for a spreadsheet for many adapted lenses. I don't have it handy but for anyone looking to adapt lenses it is a good resource.
That spreadsheet is only full of personal opinions, unfortunately. A lot of the "no vignetting" lenses causes severe (and to me totally unacceptable) vignetting.
Are you focusing much closer with the EF 40/2.8 than the example on the last page? In that case it will give less vignetting because it's a unit focusing lens, which means the image circle gets larger the closer you focus. This is also one of many reasons that the data in the spreadsheet is useless; some people only shoot closeups and thus report "no vignetting" on lenses that give heavy vignetting at infinity.
I think Makten is right in his views about the spreadsheet. It is just a summary of a bunch of people's opinions, so take it for what it is and don't consider it definitive. I certainly wouldn't buy a lens based on the recommendations there. Keep in mind you can also search this thread, which has a lot of discussion and pictures with a lot of different lenses. As usual at FM it is often better to use a google search than the internal search. Just try a search with something like, "Fred Miranda Adapting lenses to Fuji GFX Canon 40 f/2.8" and you should get quite a few links to discussion of that lens in this thread often including pictures.
He is also right about unit focussing lenses often working well for closer distances but having heavy vignetting at infinity focus. As one example, I had and used extensively with the Leica R 80 f/1.4. I was quite happy with its performance for portraits, but I vignetted considerably at infinity focus.
One last comment comment for those interested in the Canon 40 f/2.8, I think it is certainly worth considering the Fuji GF 50 f/3.5. It is not that different in focal length (basically the difference between 28mm and 35mm on FF 35mm) and it is Fuji's cheapest and smallest lens for the GFX. Despite its relatively low price it has quite strong performance, IMO.
Personally I would buy 40mm f2.8 and try it. It is $100 lens. If you like it, keep it. If not sell it. So not sure what the issue is. 50mm f3.5 still goes used for $750.
The Fuji GF 50 f/3.5 is regularly available for $600 if you shop carefully. Three have sold for that price on eBay in the last three months and one was available here for $625. The Fringe EF lens to GFX adapter is $474, so we are talking a really similar price. Personally, if I didn't have anything yet, I would go with the Fuji 50 f/3.5 unless I knew I was going to adapt other EF lenses.
