  1. :

    Is the adapter can be used with the other camera(ASI224 for example) with the correct spacing. Any plans you’ll sell adapters that will match the correct spacing for the other camera?

    • Sam Wen


      no, because the back focus of M43 lens is too short

  2. :

    Does this adapter have filter threads inside to allow for mounting a filter e.g. 1.25″ LRGB or light pollution filter for imaging?

    • Sam Wen


      no but we will provide a M42-1.25″filter adapter in the near future
      so you can put the filter in this adapter and screw to M42 inside

  3. :

    What is the back spacing in mm of this adapter? What is the combined back spacing with the camera and this adapter in mm?

    • Sam Wen


      the back spacing is 6.5mm
      the back focus of M43 camera is around 18mm

  4. :

    I have this adapter, I have put a Olympus lens on it and I can not remove the lens from the adapter. The small screw that the adapter has, I have tried to unscrew it (even removing it) and screw it again but it is impossible to quit the lens from the adapter… What can I do now?

    • Sam Wen


      you need to push down the thumb screw at first and then hold the adapter and unscrew your lens
