    I’m interesting in this adapter.
    I have one question about the aperture control pin in the Nikon F-mount lens.

    When I attatch this adapter to the F-mount lens, is the aperture fully open ajtomafically?
    Or do I have to hold the aperture control pin to full-open position with something(?) manually?

    Hello
    I’ve understood that it is possible to mount a 2″ infrared filter on this adapter. What is the thread size of the filter interface? What is the maximum filter thickness allowed ? tks

    Hello
    I’m interested to use such adapter on Nikon tele lenses, but Ii’m a bit uncomfortable with focusing issues that have been raised here.
    Has the effective thickness been reduced from 20,5 to 20mm to achieve a total 46,5 mm length?
    Thanks

      The asi1600 can be directly connected to EFW without adapter.If you have Nikon lens,this is exactly the adator you want.The following is the connection method:ASI1600+EFW+EFW-Nikon adapter+Nikon Lens.

    Dear Sam, when using my 1600 pro and the EFW, this adaptor and a nikon lens, I cannot get it to focus no matter what combination of extension I use.Is it because I am trying on distant terrestrial objects during the day?Also this adaptor seems to work well on some Nikon lenses and on others its very hard to attach, is this normal? Thanks.

    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 .
