These 3 lenses all cover 10x8, I bought the middle one a 300mm f9 Nikkor M in the late 1980s from Robert White, it had to be ordered from Japan. I planned to upgrade to 10x8 at a later. However, I found on my Wista 45DX it made the camera unstable needing almost full bellows extension and only usable in very still wind conditions.
The second, on the right, came with my first 10x8 camera, an Agfa Ansco Commercial View, the seller said it was useless he had used a 300mm Nikkor M. The lens is a 1940/1 12" (300mm) f6.8 Goerz AM Opt Dagor in a Compound #3 that is very smooth and accurate.. In fact it's an excellent lens.
The third, on the left, is a new acquisition, a 1963 300mm f4.5 Schneider Xenar in a Compound #5, it is in stunning condition, and is also quite a lot larger and heavier.
The Pros & Cons.
The 300mm Nikkor M is slow with it's f9 widest aperture but it's still relatively easy to focus. It's small and light with a Copal 1 shutter & top speed 1/400, and weighs around 310g. Very little room for movements on a 10x8 camera.
The 12" (300mm) Dagor is easier to focus because of its f6.8 aperture, heavier at 580g, reasonable size but the Compound #3 top speed is 1/100. Excellent contrast and plenty of room for movements. Could be used on a 5x4
The 300mm Xenar is very easy to focus with its f4.5 aperture, but is much larger, weighing 965g A downside is the Compound #5 top speed is 1/50.
I do have a Wray f6.3 12" Lustrar but that's a barrel lens. I have 3 10x8 Agfa Ansco cameras and will offer the Nikkor Mas an option with one of them. I prefer a 360mm f5.5 Tele Xenar for 5x4 & 7x5.
