Though, admittedly, I haven't used it wide open on 8x10- not yet, at any rate...
JB7,
How will I know if it is an older single-coated one? And are you recommending single-coating because of cost or other reason? There are quite a few on ebay and they are certainly affordable.
They've always been inexpensive, they must have made a lot of them-
Don't confuse cheapness with poor quality in this case, however. They might not be up there with the more expensive lenses, for absolute resolution, but for wet plate in camera, they could prove to be more than adequate.
Falloff can also be dealt with by lighting, if that is an option- it might be that wet plate is emphasizing the falloff due to the limitation of the dynamic range presented by the process.
The older ones are distinguished by the positioning of the engraving inside the bezel- and by having a much larger image circle than the multi coated newer ones.
You're right, there are a few available- Fujinon W, not W S ...
Well, running a quick test of something with wet plate always gets more complicated. I got pretty even light with but had the view closer in than I need, then did something wrong with the next exposure. So, I'll have to continue that tomorrow.
Thanks for the advice all. I'll keep looking into the lenses you've mentioned.

It's not much of an issue, but with wetplate and artificial light, a coated lens may act slower than it's listed. Usually UV (what wetplate is sensitive to) gets through coatings fine when I shoot outdoors, but I've noticed artificial lighting has to be VERY powerful for wetplate. I had one experience where a coated Aero lens didn't end up as fast as we thought. I'd want to do everything to limit the exposure time, both to help the sitter, and to get less motion blur.

How about 14" Kodak Commercial Ektar, image circle is 444mm.
Schneider made a Xenar 300mm f4.5. It is a tessar design, was single coated and came mounted in a huge Compound 5 shutter. According to Schneider it has an image circle of 364mm @ f16. No idea how much fall off there is wide open but at 8 to 10 feet it may not be too bad. The Schneider vintage lens catalog also lists a 360, 420 and a 480 all at f4.5. Here is the link. https://www.schneideroptics.com/info..._lenses/xenar/
