Voigtlander Color Skopar M lenses to L39/LTM, is there such a flange?

I would like to change my two Voigtlander Color Skopar VM lenses, 21mm & 25mm, to L39/LTM mount, is there such a flange? Is this possible to do?

I have been looking everywhere but so far coming up empty handed. Any pointers would be appreciated, thanks!

Not that I know of. Besides, you would need to reduce the length of the barrel by 1mm, which doesn't seem feasible.

No. You can fit LTM lenses to an M with an adapter but not the other way around.

You can buy older versions of these lenses in ltm

The flange on Leica M lenses is just 1mm thick, so mounting another flange with 1mm less is impossible. Voigtländer might have a thicker flange as they offered also M39 versions of some lenses.

Thanks Carlos, sure I do know that but I would like to see if I could put my existing lenses to use first.

Sorry, perhaps being somewhat thick myself here but I would like to see if it was possible to change the M flange for a M39 flange, are you saying that this would not be possible because the m39 flange would have to be less than 1mm, ( obviously impossible ), or what?......Thanks anyway.

The M39 flange must be 1mm less thick than the M flange. So it is only possible if the M flange that is on the lens ist thicker than 1mm. On Leica made lenses the flange is exactly 1mm.

Ok, thanks!

There is only one way i'm ware of, but it is not with a CV lens. It is with the Summaron 35/2.8 "Dual Mount" which includes a built-in LTM to M adapter. An M lens that becomes a LTM when you remove the adapter.
