Not at all. Only a few can and only a select few can cover the sensor well and be sharp in the corners and not have significant vignetting.
Maybe there's a communication issue. Here's what you wrote:
what reason is to use metabones adapter 1.26x ef-gfx ? any canon lens can cover all gfx sensor?
What's the reason to use the adapter, question mark. Separate statement: Any Canon lens can cover GFX format.
What you didn't say, or at least I didn't get this from what you wrote was that: Any Canon lens using the 1.26X adapter will cover the GFX. If that's what you meant, then I apologize as it wasn't what I read or what you wrote, and probably got lost somewhere in the translation.
Looking for a recommendation for a 40mm - 50mm (equivalent in 35mm terms) lens for the GFX, ideally in the f/1.4 range that doesn't break the bank. Would ideally like minimal vignetting that is easily correctable in post.
Any recommendations? That might be a hard set of requirements

The Sigma 50mm 1.4 ART comes to mind. I'm sure there are others as well.
I wish my Sigma 40mm f1.4 art was Canon version and not Sony. It is one big and heavy lens though. But then there aren't many 40mm f1.4 lenses out there.

Thanks to you both. I'm looking for 40-50mm equivalency, not necessarily that focal length. So anywhere between 50mm and 65mm would work. I realize there's not that many (any?) lenses between 50mm and 65mm I'm basically looking for a "walk around" lens with a fast aperture.
Any "vintage" 50mm lenses that really work well on the GFX?
Finding that 50-60mm range with both the fast aperture and being able to cover the format really limits your choices, which is why I mentioned the Sigma ART lens. I've only shot test shots in the studio to see how well it works, and it seems to work quite well being both sharp with maybe a bit of resolution falloff in the corners wide open but also covering the format, and if you're going to using the lens the I think you are, absolute sharpness in the edges wide open is not going to be an issue. The lens seems to focus better for me on the GFX 100s with the Fringer adapter than it does on my Canon's. Is it within your budget is another question. Another lens that works really well as long as you're under about ten feet, for slightly wider environmental portraiture and such, is the Canon 35mm 1.4 II. About a 28mm equivalent but really sharp where you need it to be for many types of shots but just having to know that it will vignette at longer distances. But a really great look to those types of images.
There are lenses like the Zeiss Otus which will work but outlandishly expensive, and perhaps some of the Rokkors in the 55-58mm focal length range but tracking them down and figuring out which ones are the best is time consuming.

Yes... but it depends on how important "fast aperture" is to you.
What's your budget and what's your appetite for modifying lenses? I've adapted a Mamiya G 50mm f/4 and just love it. It's already very good across the whole frame at f/4, so you can use it wide open. But f/4 isn't remotely "fast" if you you're looking at f/1.4 lenses.
Fun fact, I would say the Mamiya G 50/4 is easily as good as the Fujinon GF 50/3.5 at f/5.6 and smaller, and I can make a case for it matching the GF lens wide open.
For a much simpler solution that requires no modifications (just a suitable adapter), you could look at the Pentax-A 645 55/2.8. There are some very happy users of this lens. It's not the strongest one in the Pentax-A 645 lineup; I evaluated it as a lens for my tilt-shift outfit, and found it lacking at the edges until f/11. People who use it without movements and aren't fussed about the edges love it.
And for a fantastic but big and heavy solution, the third generation Pentax 67 55/4 is excellent. However, it's so big...
Try Sigma 50mm f1.4. Even though I haven't tried it myself, I don't think anything would work better than that. I am holding for the 55mm f1.7. It will be nice but expensive for sure.

Thanks, that is helpful. I have a couple of Rokkors that I'd ideally like to try (50/1.4, 50/2, 45/2), but I don't love the idea of buying a $100+ adapter and deciding they don't work or I don't like them.

Unfortunately, "fast" is the whole purpose for me of adapting lenses to this system. I'm looking for shallow depth of field, specifically, in a "walk-around" style focal length. So really anything over f/2 won't really work.

It's big and a bit more than I'd like to spend. But good recommendation, thanks!

The Mitakon Speedmaster 65/1.4 has an old-school draw wide-open to about f/2.8. It's got a nice amount of undercorrected SA for some glowy wide open shots. CA is mostly okay. Spherochromatism is not well-addressed, but it's nothing you can't mostly clear in post. Flare resistance isn't high, but it flares pretty. It's native mount and on sale right now at B&H.
If you want something with a more modern approach, you could go a bit wider with the IRIX 45/1.4. It's a lovely lens. Great color, generally nice bokeh, sharp but with pleasing focus transitions, all-around well corrected and a brilliant landscaper stopped down to f/5.6 or greater. It's also native mount and on sale right now at B&H.
One of those is your best bet on fast with minimal vignetting at a reasonable price. They're both big and heavy (the Mitakon's about a kilo, and the IRIX is 100g heavier) but they'll certainly beat most 135-format lenses adapted.
Otherwise, something needs to give. You could compromise on the speed and go with something like the Pentax 645 55/2.8, which is an excellent lens and would be fantastic on a tilt/shift adapter. Alternately, you can search for a fast 135 lens that doesn't vignette much on it's format wide open as a starting place, but that may be something of a fool's errand.

canon ef 35/2 ,ef 45/2.8, voigtlander 40/2 sl ii, cano ef 50/1.4 and ef50/1.8 works

tried today canon ef 50/1.4 usm on gfx50r via techart adapter, very nice pictures even at f1.4.
Really? That is such a mediocre lens and even less so wide open. I suppose if you like that veiled, soft focus effect and you want that then it might be okay. But in addition, the autofocus is very slow on that lens and sooner or later the AF motor WILL go out. They do on every single one of them, but why don't you post your examples both full frame and 100 percent crops so we can all learn.

The 50f1.4 is very soft wide open and needs to be stopped down to at least f2.8 to start getting sharp.
Yep. That's my experience too. Quite good by 5.6 or f/8 but then why have a 1.4 lens unless you really like that soft focus look. I don't think this lens is going to get any better by slapping in on a GFX camera but some might like it.

ef50/1.4 soft glow at 1.4 and this superior for portrets,no need retouch skin in post,also no need any 100% zoom for actual photos or print,sharp from f1.8,but im no need keep it,as have light ef40/2.8 for gfx and it same sharp at 2.8 as gf50 shows at f3.5 ,at f3,5 ef40 sharper vs gf50 at f3,5, focus speed very fast with techart adapter
