Unknown ball lens

Amazing! Well done!

Thanks so much!

You're examples were at f/64? Sharp in the middle, and very soft as you move outwards.

The problem might be the fact that the glass isn't in great shape. Working on that

Ahh, but I’ll bet they could be made in a specialist precision shop. I’ve heard there’s one in Arkansas

It should be said that a Hypergon does not look like any other lens. I assume it would take specialized equipment to produce.

Well a first rate hypergon in good shape is a LOT shrper than a pin hole,. but the glass here isn't great. I'm working on that problem

What in particular is wrong with the glass?

What in particular is wrong with the glass?

Scratches, both tiny and larger. Disappointing... I will be putting up some remediation pictures soon

Regarding this camera project, I’ve recently been researching repairing scratched camera lenses. I did a lot of testing on ways to improve lenses that have this problem. Please visit my blog for the results and to see my tests: https://siskinphoto.com/blog/?p=5220 It didn’t help this lens as much as I would have liked, but it did work on other lenses. Thanks for your attention

Another shot from Gallisteo with the new Superwide camera. T-Max 100 processed in Xtol. 4X5 negative. Unfortunate that the the lens isn't better, but I'm still working on it. Thanks for your attention
