To Christoph Hopf: Have you talked to your aunt?

To Dietmar Zonewicz: I'm interested in buying the lens and only the lens(not the rods etc.). I think 1500 is pretty expensive!

Does anybody know if that xenon lens:

would work with the xl-1 and homebuilt adaptor??????

Thanks

I phoned PStecnik and it seems that the relay lens alone will cost 1000 euro. Pretty much!

If I bought that lens - could I just mount a GG and a lens - and then start shooting? or would I still need to get an achromatic adaptor and stuff???


Thanks!

You're going to need an achromatic adaptor, or some other method of getting the relay lens to focus onto the GG without vignetting the image.

not 100% sure, but it seems if they will send you the relay lens, than all you need is to build the gg and mount in front of it. if you look at the pdf of the innards of the lens, you can probably deduce where the "relay" ends and the gg element part begins. If there are no more optics (besides gg), then yes, all you have to do is put a gg in front of it and get a mount.

everyone check out the other thread, its starting to see some more life.

P+S have no own lens. They use a 25mm high quality c-mount lens from Schneider Kreuznach. This lens is a very fast lens (under 1), so also 16mm filmmakers love this lens since years. Here in germany the lens cost round 900,- euro.

Close behind the GG is a condenser lens. This is because the hotspot, but P+S use NO other lens. With the Schneider lens there is no vignetting in the image and it can focus on short distance. The distance between lens and GG is round 11cm (prisms + mirror = 10cm).

If you wont a bright picture, but without DOF, you can remove the GG (but not the condenser).

This way work a adapter form Angenieux:

http://www.smsprod.com/products/lenses/angenieux4.html

It reduce the image size from 35mm film lenses to a video sensor. But this very expensive part have no prism, so the picture is upside down. Okay this is only for 2/3" sensors, but just have a look inside.

Rai, are you saying that p+s uses the Angenieux as their relay lens? or are you saying that they use another companies lens as their relay lens, one that we could purchase on our own. If so, that is great news, as the relay lens is where most of us are stuck on our xl1 systems.

stephen, read carefully what rai wrote.
Everything is in the first paragraph: Schneider Kreuznach 25mm f 1:0,95 - the only thing to change is the mount (from c-mount to xl-mount).

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

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!

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.

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