This is waaay too expensive, especially given the careless adaption which not only cannot focus to infinity as usual (these X-ray lenses generally have no register depth that would permit that), but can't be focused at all (being rigid mounted for 1m distance) and has no aperture either...

Optics is worth it's money for sure. Adapter though fully useless. Focus on about 1m yes, but showing magnified cropped picture i think (like with 6x tele-converter). Flange for sharp photo is like 3-5mm.

An Xray lens which can only focus quite near. Adaption usually are fixed, so no focus possible. Quite overpriced as you can get such a lens for around $50.

You might have luck to snatch such lens as industrial waste. But when seeing it and holding it you know it's worth the price. Hopefully they will soon get bodies they deserve Smile.
