Zeiss Jena mirror lenses

[gcrimmins]

I was just reading about the Carl Zeiss Jena 500m f/4 and 1000 f/5.6 mirror lenses. They both sound like interesting lenses. I have a feeling they don't often show up on the used market, and that they are probably expensive when they do. Is this the case?

They are superb quality lenses and made in small amount, both can be expensive approx 2000 USD

Friend of mine has both lenses as you able to see on second picture.

The 1000mm is quite a monster, had that some time ago but sold it later. Just very unpractical to use, despite the excellent optical qulaity. Another point is that you can't stop down this type of lens.
