C-Mount: Navigation Berlin Hypomediar and Schneider Xenon

exaklaus · Expire: 2011-12-02

Received a nice pair of C-mount lenses:
- Siemens-Spiegel-Hypomediar 1:6,8 F=20cm mirror lens with diaphragm.
- Schneider-Kreuznach Xenon F:1:1,5 f=2,5cm

They came with a dirtbag of a Siemens cine camera. Filthy and baaaaah
I took the lenses and threw the Siemens out in the Bay.

Of course theese lenses are absolutly vignetting on my X-E1, but nevertheless I like them.
The Hypomediar is a bit stiff at focussing and so it is tricky to get a sharp shot.

Here are a few ones just taken in our garden. Nearly winter, so do not expect flower shots.

Have you tried to remove the hood of the Hypomediar? I think it may cover a larger area than the Xenon?

It is not the hood, which is part of the body and not removeable. It is the back part, which is very narrow.

I see. It is the rare baffle which blocks the light. If we can remove the rear part of the lens, we might be able to modify it to get a bigger image circle.

Hmm, interesting, that mirror lens especially. Was tempted but never gave it a try,
great that my guts feeling prevented me from buying Wink

I was tempted for years....
Finally got it and glad to have it.
Don't really need it, as I have one or two other lenses, I can use.
