I just bought a relaylens from P+S for 1090 euro. But it doesn't look exactly like the lens you are showing in the link. The iris ring is closer to the camera than the focus ring. But perhaps they are otherwise identical!

Anders,
what is your plan to mount the lens to your camera?
Im curious to know what you find out from your lens, fill me in.

Anders,
Schneider Kreuznach made the inside lenses but the Housing came in differnt design and under differnt names (Angenieux or Schneider Kreuznach or others). But inside it is the same

So basically, if you buy the relay lense from Schneider, you then have to mount your own ground glass in front of it, and somehow connect a mount (PL, Nikon, whatever) to the ground glass.

Look at this

My company have made the Canon Lens Adataper.
And also all other parts you need for a 35mm vibration solution. The case is ALU, it have 2 build-in light weight support rods. The vibration drive need 6V DC, but only 35mA

Great. How much does it cost to make? Are you going to distribute plans or are you willing to make more and sell them?

I was wondering about the whole prism (rotate image) question. Doesn't the prism and mirror steal F-stops??
Because on the XL-1 you can simply flip the eyepiece to the other side and the image is corrected. Then in post you can just use the:

during capture (without loss I hope). If this is true then I would rather avoid bothering with prism and mirrors.

Or am I wrong???

We can sell the relay lens for Euro 900,- (round $ 1.115,-)

We found a cheaper one, but i dont know how good it is. We check it next 2 weeks

A mount adapter (to connect the lens to the Canon) cost Euro 198,- ( $ 245,- )

BTW: only with this lens (without the other GG adapter parts) you can make good night shoots. ( F stop = 0,95 )

Anders,
yes, the prism "steal" a little bit light but. In F-stops? I think only 0,05.

The prism is a expensive part, because you need a "big on" with inside more than 40mm diameter and it must be color corrected. I will check out the best price till next week Without the prism you need 10cm more distance.

I don't understand why it needs to have 10 cm more distance!
In a normal still-camera the lens is only about 5 cm from the film... I can see that without the prism and mirror the light will travel a shorter distance but... I'm sure that you are correct but could you explain it to me?

I would properly be interested in buying a colorcorrected prism then - So it would really like to know the best price you find.

In the PDF file showing the PRO35 there is something called "Schutz glas" - Is that a fresnel??

Thanks

schutzglas means protective glas

The way through a prism is longer than the prism outside. A still-camera have also build in a prism. So the way in a still-camera is also more then the outside dimensions.

But in different to the still-camera prism, you need a bigger one, because the relay lens have more than 30mm light circle. Thats why you need the big prism and thats why it take more distance.

Okay, you can mount a macro lens in front of the relaylens to reduce the distance, but than you will have some distortions.

The "SCHUTZ GLAS(S)" is only a clear glass to protect (SCHUTZ=protection) the inside parts for dust and dirt.

To reduce (elimate) the hot spot there is a convex lens with the plan side very near behind the vibration GG (sorry last day i call this condenser, thats wrong)

You say that the prism is expensive - what are talking here, $100 ? $500??????
