Hi, good questions.I'm looking at a Fotodiox adapter for my equipment. The one I need has a lens in it and is for SLR so focus is no issue. What about yours? Is there a lens in it? How do you set exposure? Is there something that keeps the lens stopped down? How about focus?
Thanks for your reply. I was curious that M42 could mount to Leica M and still focus at infinity, so I looked up the site. I could still not find your adapter on the site, but I found the Rollei SL to Nikon adapter I had always been looking for. In that case the only way to have infinity focus is with an extra optic element. It is less then $40, so not much risk in trying it. I'd like to try my Zeiss 35mm 1.4 on my Nikon F100. I also see they have reasonably priced replacement alligator-connector Rolleiflex TLR camera straps. I found a New one about 15 years ago for about $150.Hi, good questions.
1. The adapter I used was for a SLR camera lens (thread-mount M42) to be mounted on a Leica rangefinder body. So my mount is just a tube with the correct fittings on each end. There is no glass in it.
2. Exposure: I use a handheld Gossen Luna Pro digital light meter. I read the exposure from the meter and transfer shutter speed to the camera and f-stop to the lens manually.
3. The adapter pushes the little pin on the back of the Takumar lens, so as I turn the aperture ring, the lens opens or closes.
4. Focus: manual with no rangefinder linkage at all. I edited my original post to state this.

If the Rollei to Nikon adapter has a 1.4X factor then your 35mm f1.4 will become a 49mm f2 lens, probably with really bad edges and corners until you stop down to f8 or even f11.Fotodiox website shows this image for another adapter, maybe the Rollei to Nikon adapter is similar. The FAQ also indicates the factor is 1.4x for the flange focal length but it does not mention field of view or effective aperture changing though Fotodiox responded to a question here indicating a reduction if field of view with the adapter:

A plus is that is seems to be three glass elements that can come out, making the adapter an extension tube for close up photography.
I may get the adapter and report back.

Since it is so inexpensive I may get it just to see what it does. I do still have six working Rollei bodies for my Rollei QBM lenses.If the Rollei to Nikon adapter has a 1.4X factor then your 35mm f1.4 will become a 49mm f2 lens, probably with really bad edges and corners until you stop down to f8 or even f11.
This is the one via Amazon (in USA):Thanks for your reply. I was curious that M42 could mount to Leica M and still focus at infinity, so I looked up the site.

So I bought a $20 Fotodiox M42-Leica M adapter and did a test run.
