    what is the specification of the thread that connects the two parts of Nikon lens Adapter for EFW & ASI1600

    • Sam Wen



  6. :

    Thank you for your answer Sam concerning the thread specification above.
    Unfortunately there is a misunderstanding. I know that the Thread towards the camera is M42x0.75.
    What I wanted to know is the thread in the middle of the adaptor where you combine the two parts of the
    adaptor .
