That looks awesome. How much do those things go for these days?

With that lens and the sensitivity of the FS100, you could probably light the scene by the light not escaping from a black hole! :) Definitely interested to see what you get!

Got this one for about 300 Euros. A bit pricey, but it's in pristine condition.
I've seen them go for as low as 50$ though.

Here's a new Kowa 42mm 0.75 for 130$

Hello

I found your posting for this unusual lens.

I also have one of these interesting lenses (as well as the even larger E65/0.75) and I just wanted to know how you found a way of reliably attaching it to a camera?

I have found that you can get quite a nice image by removing the rear element and simply holding it up to the sensor of a mirror-less camera like a Sony NEX-5 (E-mount).
This is, however a very awkward and precarious arrangement and not very practical.

You can get an adapter for the NEX that mounts 'C-Mount' lenses (i.e. small CCTV like lenses) and this is almost a fit for the Rayxar. Unfortunately, the hole (with its internal thread) needs to be a couple of millimeters wider.
I have not been able to find anyone who can machine the mount to make this hole wider AND put in a new internal thread.
You need a thread so that you can focus.

Any ideas would be most welcome.
