Do you have any full frame digital camera? Why don't you use it with Buhl and your other rare lens?
Buhl 240mm f2.5 - what that? I can not find this lens.

I do not have the full-frame digital Tiagra Girl. Most of my gears are analog formats up to 8x10 camera. For digital I used to have large formats but I sold most of them and only keeping m4/3 and smaller formats due to compactness and the ability to use small vintage cine lenses/c-mount lenses.

Regarding coverage ability, Buhl lenses and others have large image circle. To make use most of it, you need to have a format that is suitable to take advantage of the thin bokeh. I do not use full-frame on Buhl because it does not allow thin DOF . The only thing that you want to mount large image circle lenses on smaller format is IF the lenses have wonderful bokeh, and Buhl and Hektors lenses have OK but not great bokeh, therefore I have no incentive to mount them on smaller format.

Yes, I have two 240mm f2.5 buhls. They are the fastest among Buhl lenses (250mm doesn't count since it has f-stop of 2.8 or f2.9).

Elgeet Navitar 111mm f/1.5 + 0.72x zhongyi speedbooster + epl5

Lens is 7-element coated . Large coverage up to 4x5 but it is good for medium format. It has identical Aero Ektar bokeh. I like to use it on smaller sensors due to high resolving power and large bokeh size on smaller format. Thinking of mounting it on a 6x4.5 film camera

Artwork. But a little more sharpness, maybe?

Optic is pretty decent but I used it on half-frame digital sensor along with 0.72x which degraded its sharpness. Best use on full-frame and medium format, but I love the bokeh .It's main my working lens on m4/3 format , perhaps I should bump post-processing sharpness a little .

Yeah the 240mm f2.5 is pretty rare. You can see how it looks here on my facebook link https://www.facebook.com/rendition.noit/posts/1659400557682100

The coverage for Buhl 229mm and 240mm are 4x5 and 5x7 if you remove the rear. The Hektor design has large coverage and I think the 240mm covers 8x10 but I do not have a proper subject to test it indoor.

Thanks ! It's a triplet lens , best work for 8x10 format. I have a 340mm f2.4 heliar-type lens somewhere but I can't mount it on 8x10 due to the size and big rear. Most of my 300mm-500mm lenses are mounted on 8x10 camera. I am thinking of building a 16x20 cameras and maybe larger cams due to the lenses I have.

I am an enthusiast lenses enthusiast from Arizona, U.S . Quite a few of us shoot large format and analog here :D . I have been following this thread for a year or two now.

Buhl 240mm f2.5 + graflex series D + fuji fp3000b negative scan
Buhl 240mm is hektor-design 4-elements in 3 groups. Coverage is 4x5 and 5x7 and 8x10 portrait but I do not test on 8x10 yet.

FOV as 35mm full-frame is 0.32x(240mm f2.5) = 76.8mm f/0.8

я думаю тут всему виной атмосфера, ч/б-елость, и руки мастера, в цвете оно выглядело бы не так фотогуманно

Yes that one if you use small lenses. But for faster/heavier lenses it does not work too well. Rather, few of us have already switched to a sturdier and better-built helicoid like this one:

Ebay 252508683434

The most sturdy and best built m65 helicoid is from this seller
