The lens can be used very well for landscape on FF. See HelenaN's work on the thread for the lens for wonderful examples, but I agree on the GFX it only covers the image circle for portrait distances and even there it is much better if you crop to 4 X 5 which is only a small crop to a 52.8 image circle but that last outer part is especially bad.
I'll give it a look! Different ways of seeing I suppose but I generally see landscapes in either wide angle or telephoto fields of view so I typically don't think of something like a 75mm for landscape.

The Opera 50 1.4 alias HD PENTAX-D FA50mmF1.4 SDM AW is one of the lenses I prefer all lenses combined except the SL Leica lenses. Their bokeh is an example of what makes these lenses unique!
Interesting I didn't know there was a twin model. Yeah, the bokeh is very lush even when I go overboard on the clarity/contrast. Perfect at the distance I use the 50 for.

The CV 75 1.5 is not a bad landscape lens on full frame:
Yeah I saw that thread it's just not a focal length I think of for landscapes and I'm just generally not a landscape shooter either. So my comment was meant more my use personally.

Nikon 35mm f2.8 PC looks good on the 50R. Full coverage at all apertures. 5 degrees of vertical tilt seems to be good, at 10 degrees the top shifted edge is smearing somewhat.

Does the 28 cover it? lol I just assumed since the otus 28 doesn't the sigma wouldn't either.
It doesn't, but it is very close, I would say about 50mm diameter image circle at infinity. I bought the Sigma 28/1.4 Art to check since I couldn't find a single sample image online, but unfortunately it doesn't quite cover. At very close focus distances it does cover (think flowers, near macro), and for the most part no cropping is needed for environmental portraiture done indoors (outdoors the sky gives it away).
Curious if anyone has tried shimming adapters to get infinity accurate? I have two Pentax 645 adapters (FotodioX Pro Tilt-Shift TLT ROKR PT645-GFX, and a no-name ebay model) and neither is accurate for infinity. The no-name adapter is a bit closer of the two but not quite there. I would like to get the infinity stop accurate and I think it would also made the 45-85 zoom not change focus when zoomed. I assume it is easier to shim the GFX side of the adapters.
On a tangent I also modeled up a set of shims to allow this ring to fit the Fotodiox adapter without modification. STL here.
I'm going back and forth on the Fuji GFX 23mm as I prefer zooms on the wide end. From some research, it seemed as if the Sigma ART (Canon mount) zooms might provide an option when adapted to the GFX 100s, so I have the 12-24 and 14-24 to test with. Full sized JPG's for review linked below, just before the embedded images.
Initial results are pushing towards the 14-24 being the better of the two lenses on the GFX 100 platform.. Take a look and see what you think. Including the Fuji GF 23mm shot, the 14-24mm shot @ 21mm (I tested it at 14mm, 18mm, 21mm.. seems like 18-21mm was the sweet spot). I have another test I can share of trees, but motion of the leaves may have confused things a bit. Including the 14mm shot for reference, the vignetting is due to the hood, not lack of sensor coverage.
These were all shot at 1/80, f11, ISO 100, tripod, remote shutter release, mechanical shutter. Processed in C1, no adjustments made, just in and out. I'm assuming the GF 23mm had its lens profile applied, not sure what C1 does by default on that front.
I think the Sigma zoom is doing an admirable job keeping up, and the flexibility it provides may make it an interseting wide-angle option on the GFX100 sensor. I'm still not sure if it's as good as the 23mm though, but it's very close.. what do you all think?

Need to test flare performance, and then there's filters to consider..
I really think the options for ultra wide are pretty limited. You can go with the Fuji GF 23. You can go even wider with the Laowa 17. You can go with the Canon 24 or 17 TSE. You can go with the Nikon 19 tilt shift. You can go with one of the image circle expanding converters and use a FF lens or you can use a FF lens and crop. Only the latter two options allow a zoom, and they both involve pretty big compromises. For what it is worth I used the Laowa Magic Format converter and it worked pretty well with the Zeiss Milvus 18 f/2.8, but I never used it with a zoom. I think with the new 100 MP camera cropping to something like a 45mm image circle ought to be a pretty strong option. You would still get quite nice dynamic range and almost 70 MP.
I would think an ultra wide zoom has to be close to the next lens Fuji will make, so with patience I think there will be a GF ultra wide option.

Did you try the Milvus 18f2.8 directly on the GFX? Which percentage of image does it cover?
With Format Converter it’s FOV is just like the Fuji 23, so that would be the better choice, isn’t it?
