8x10 lens that dont vignette wide open?

[ryanmills]

This is very similar to a post i made yesterday but I just got to thinking maybe im asking the wrong question or the format does not allow it. In the ~250mm focal length for 8x10 are there any modern lens that cover well enough to avoid heavy vignetting wide open at say a full body length distance? I shoot in fairly low light indoors a lot and f/16 just does not happen as much as I would like. A light vignette is fixed easy enough in post but really dark to near nothing I hate and have to crop out.

240 mm Apo Sironar S and probably also the N. But no large format lens is designed to be used wide open. Performance is greatly better at the design aperture of f22.

I have the Rodenstock Apo Sironar N and its bad wide open, but its really meant more for 5x7. I would love to try the S but i have had a hard time finding one for a resonable price. I get no large format lets or most lens for that matter are meant to be used wide open but some handle it much better than others.

Fuji 250 f6.7
Cheap, sharp and contrasty with lots of movements for 8x10

The N is designed to cover 810 and more then does so at optimal aperture.

Moving up to 8x10 has it's disadvantages, especially for portrait work. The fuji 250 has a fair amount of coverage but I would rather shoot with 4x5 than have a large amout of blurry shots.

The 240 Apo-Sironar-S is the only late-model 240/250 plasmat that is specified for 75 degrees of coverage at f/22; the rest are specified for 72 degrees or less. Among all the alternatives I'd say it's the likeliest bet to provide a meaningful improvement in falloff wide open compared to the 240 Apo-Sironar-N. But whether it will be enough of an improvement to justify the extra cost, only you can say. Yes, that puts you in a difficult position, as these days it's hard to lay your hands on one to test before committing to a purchase.

I shoot a Nikon 300M wide open at f/9 with no vignette and it is quite sharp.

But no large format lens is designed to be used wide open.

Myriad Verito, Cooke et al users would disagree with this opinion.

Indeed, no large format lens should ever be castrated and lobotomized by closing down the aperture and stealing away its very soul...

I agree with this statment so much! The magic happens wide open :)

Vignett has many meanings in the English language. So now we are using it to describe light falloff? If you look at the light falloff curves of any large-aperture large format lens, you will see a hotspot at the center. Personally I'd only refer to a lens "vignetting" if the projected image goes to black at the edges or corners.

I have a Zeiss Jena 250mm f 3.5 lens it covers 8x10 fully open and I even can shift a bit!

If you read the original post he stated "modern lenses".

[mdarnton]

I would think that for modern lenses for the usual definition of vignetting, you can just take the manufacturer's word for it. Modern lenses rather than fading slowly at the edges, going bad long before going dark, seem more to go good, then bam!, nothing, like my 65mm Super Angulon (below on 5x7):

Try a 14 3/4" Calumet.

I did.

I also read where you wrote "...NO large format lens..." Seems you feel that you can claim all lenses, yet I must stick to some subjective criterium. Fair enough.

So, to counter your erroneous claim by listing MODERN LF lenses, myriad Cooke PS945, Imagon, Fujinon SF and Wollaston users would disagree with this opinion.
