  1. :

    Is there any way to use this adapter with your other cameras like an ASI290MC? Can I use a T2 extension to get the correct backfocus? Like a 10mm or a variable spacer?

    • Sam Wen


      no, ASI290 cannot use it
      there is no such adapter for 290 yet

  2. :

    can i use this adapter for the ASI071MC?

    • Sam Wen


      no, this is for 1600 only

  3. (verified owner):

    an idea how controlled diafragma with Electronic FE lens? For example FE55, FE90, FE70-200, All not have ring of aberture. Only FE35 Zeiss distagon, FE50 Zeiss, and a FE Manual lenses made for others brands..

  4. (verified owner):

    So..i have a solution! only with electronic FE LENS:
    1r: put the lens into camera. Turn ON the camera (like sony A7 series or NEX or 6..)
    2nd: select diaphrag apperture (for example f4 in sony ZEISS 55 1.8)
    3rd: put off the lens with camera ON. And we have the f selected!
    4rt: tape the lens mount of the camera (for not pollution into sensor ;))
    5th: Put the lens into adapter to ASI1600!

    • Sam Wen


      sounds good!

  5. :

    How do you focus an electronic FE lens with this adapter? Does the focus ring still work without power to the lens?

    • Sam Wen


      you can only try to add spacer

  6. :

    Would the T2-T2 adapter allow this to work on the ASI185mc.

    • Sam Wen


      no, this is only for 1600 or these camera whose back focus distance is 6.5mm

  7. (verified owner):

    How to unlock the adapter from the lenses? i cant remove it from my sony lenses….

    • Sam Wen


      Please press the button down and then you can screw off the lens

  8. (verified owner):

    ups…. i have solved the problem… you have to push back the little knop on the side…:-)

    • Sam Wen


      good to know

  9. :


    Can this be used in conjunction with the ZWO EFW Mini Filter wheel? or will this create problems with the back focus distance resulting in elongated stars?


    • Sam Wen


      no, the back focus of E mount is too short
