Anyone fancy an ULF lens?

I happen to have a piece of glass that has an effective focal length of about 5' and it's about 3" wide... so that's a 60" f/20 lens? Looks like it projects an image just larger than 1:1 ratio

Actually, I'm interested!

I've got a creaky old 16x20 (18x22, technically) that I'm always hoping I can find a long lens for (normal is 600mm/24") that isn't insanely expensive.

Do you have any more information about it?

Like its weight in tons?

Thanks!

It's a single cell of glass from a bunch that I've acquired from a few years ago. There's no barrel, so you'll need to put something together. I put the thread up as a bit of a joke, not expecting anyone to bite.
