Those look impressive, how does the EF 16-35mm compare with the Fuji 20-35. I am undecided which one to buy. I have a fringer EF adapter and the 16-35mm is considerably cheaper.
My new GF 20-35 had to be repaired as it was a brick right out of the box. Sadly I don’t know how it compares to the Canon lens yet. I was quite pleased with the Canon the other night, but I’ll know soon how they compare as my 20-35 is on its way back to me. I don’t think you can go wrong if you opt to buy the Canon, as the Fringer adapter is quite capable.
New (and boring) test today with my recently arrived Pentax 645 300mm f4 A lens. We're staying at a campground in Lake Worth Florida. It's even more sharp than the Pentax 67 90-180mm I just tested - and it needed almost no sharpening (one unsharp mask application which I tend to do for most lenses I own). Focus ring is a little too free moving for me, but I had no real problems. This was shot in gusty 20-30mph winds at ISO 800 and 1/640. Not sure of the aperture. Excuse the boring subject of someone's small motor home, but it shows how capable this lens is. The cropped shot is from the same exact non-cropped image. Another MF keeper for landscape and similar pursuits...

Didn't you say in another thread that you bought a used, albeit mint looking, lens?
Yes, I did. It turns out it was literally never used or mounted. Hence I consider it new and Fuji readily repaired it without any questions about who was the original purchaser.
I haven't heard of any new ones being duds. I'll be sure to give mine a thorough test. If your lens hadn't been out of it's original packing materials I'd consider it a factory dud, but once it has, who knows until you test it.

The tech I spoke to at Fuji was careful in his word choice, but I’m guessing this isn’t the first main board they had to replace. I wonder if those with sporadic lock ups on this lens have less damage on the main board which allows for proper operation most of the time. I’m just glad they quickly fixed mine. Good luck with your copy. I can’t wait to get mine so I can use it.

We can see that this Pentax 300mm is good in the center but how does it fare at the edges and in the corners and how far do you have to stop it down for the corners to get sharp if they aren't already wide open?

I'll have to take another image with this lens that will allow me to better assess its corner sharpness. I'll try using several apertures, but the dumb adapter (Fotodiox Pro) doesn't allow for an exact determination. I'll also try and find a better target for checking corner sharpness (a flat wall or similar). I wish Fringer would come up with an active adapter for P645 to GFX. There must be something in the circuitry that makes it difficult or impossible.
My biggest problem with more tests that I ran today is achieving critical focus with manual focus lenses (and even AF lenses). I need to improve my focus abilities to properly evaluate these older lenses. The P67 90-180 sometimes seems very sharp and other times seems soft. Today I re-tested the P67 90-180 and did my first tests with the P645 150-300. I also did extensive testing with the Canon 100-400mkII with the rear baffle removed. I also tried my Canon 400mm f4 DO II and the 600f4 IS mkII. Even with the Fringer adapter and AF enabled, I think I missed focus a few times on my target area due to the focus spot being a little too big. I've been reading this afternoon about better focusing techniques.
The P645 150-300 shows real promise but there were inconsistent results . Same with the 90-180mm. I also got inconsistent results with the 100-400, but also likely due to the focus spot size I was using. All of these lenses I mentioned can achieve really nice renderings, but the sharpest images came from the P645 300mm, 100-400 (from 100 up to 400), the 400mmf4, and the 600mm f4 (but with clear vignetting). The P645 150-300 sharpness is close to prime level when I seem to nail the focus.
Tokina Opera 50mm F1.4 FF works well with GFX. Good sharpness too. I tried this lens once with Viltrox adapter before the adapter died on me the next day.

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
I do have the Pentax 645 A 300mm. Good lens on my (gone) Pentax 645Z. Did not try it yet on my Fuji GFX 100s. I use the Pentax 67 55-100 quiet a lot on it. Outstanding zoom.
In Europe that car is called Peogeot. I made a camper out of ot myself.
I’m here with the answer to a question that no one is asking. The Minolta MD 50mm f/1.7 vignettes on the 100s. Its covers almost half of the image wide open and never goes away stopped down. It did resolve details better than I expected it would, not bad for a lens that can be bought these days for around $30. Overall, no regrets in spending $100 on an adapter that lets me play with some of my old glass.
I selected the wrong lens from the pre-saved list so it shows up wrong in the EXIF.

Yes, Tokina Opera 50 1.4 is great, also the Samyang/Rokinon XP/SP 50 1.2 also great, but like mentioned Opera is more practical.
