“How-to use m42 lens with the Voigtländer VSL 1 (BM)”?

VSL-1 (BM) can use only the QBM (Quick Bayonet Mount) lens. I found the Rollei lens converter in my local camera.. (See Fig 1.)
I am not sure….”It can use with my VSL-1(BM).” Who have experience?
Please share your opinion.
Thank in advance

Yes, you can use it.

When it's screwed on to a M42 lens, it's just like a QBM lens (non-full aperture metering version).
That means you need to use stop-down metering (push in the depth of field preview button).

Have fun... It's one of the best & fastest ways to use M42 lenses!
