Question

Hi all I have been miss-sold a LUDWIG MEYER 50-2.9 vintage lens….according to the eBay listing it has an M42 screw mount…..
It arrived today looking good, in a little leather case with both original caps in place…but…instead of an M 42 thread, it has a small bayonet type conectionwith three flanges….see photo.
It looks to be a good lens…. I’m left wondering what adapter I need now, for my M 4/3 CAMERA?
You win some you lose some..

Hobbo. It looks like it might be a QBM bayonet as fitted to Rolleiflex SL35 SLR's and some related Voigtlander cameras but please satisfy yourself that this is so before you buy anything.
CORRECTION. I have just looked this up, the lens was made for Exacta or Exakta - I am not so familiar with that bayonet, again check it out in case it is a variation!

If it's an Exakta fitting, there's one on eBay that seems to be for M4/3. If it was me, I think I'd be rejecting the lens as wrongly described due to the lens fitting though.
