I wonder what something like this 100mm diameter 100mm focal length lens would do. I calculate it would be an f1, if you could figure out a way to mount it without stopping it down.

I bet it would be soft and colorful.

That linked lens is actually a reducing lens and not a magnifying lens so it wouldn’t work.

I'm not sure this one would work with a bellows or helicoid 50m focal length 100mm diameter double convex.

In my experience cheaper is better. As long as it's glass.

I mis read that last one it was 50cm focal length.

This one is an F1 100mm lens double convex.

Now how to attach to a bellows.  It might be too big for a bellows.  I use a 105 focal length enlarger lens on my bellows, and it will focus to infinity with room to spare.  I think even a 75 or 80 mm lens would, but its only an f5.6.

Maybe a short helicoid and some sort of adapter.
