8x10 Portrait Lens 240/300/360 ?

I'd worry less about the specific lens and more about making the photo. Any 14" to 24" lens that covers 810 can be used depending on how much room and bellows extension you have.

Here's an interpolation of a nomograph by Kodak on equivalent focal lengths across various film formats...

Trying to find the lens on 8x10 that would emulate my 85 or 105 Nikkor on 35mm.

The math is simple:

For the most common aspect ratios the standard focal length equals the format diagonal.
Take that length and chose a lens in the same relation to it as your 85 or 105mm lens is to ta 50mm lens.

Isn't 43mm the diagonal of 35mm?

I guess that makes the math even easier: double it to get an 85mm.

So maybe a process lens? An APO-Nikkor 610mm f/9 would do the trick nicely--wide open it'd be about the same as an 85mm f/1.2L, too!
