  1. :

    Can I use this adapter with the ZWO manual filter wheel?
    Will it be possible to reach optimal focus that way?

    • Sam Wen


      no, the back focus of this adapter is too long
      but we will make a short one to work with our MFW or EFW

  2. :

    Does it fit 2″ filters like the one for ASI1600?

    • Sam Wen


      yes, but you need to get the glass out and put it inside this adapter and hold it with the hold ring from the 2″ filter

  3. :

    Just to be sure:

    I have a canon EF 75-300mm lens (standard EF mount) and an ASI120MC. Is the EOS-T2 adapter sufficient to connect these two, or do I need some other adapter as well?

    • Sam Wen


      yes, it’s adjustable and support back focus from 10mm to 20mm

  4. :

    Hi Sam,
    Is the Nikon version coming out soon?

    • Sam Wen


      bad news, no

  5. :

    Does it have a place to screw in a M48 filter?


    • Sam Wen


      yes, build in M48 screws
      but it’s better to put 2″ filter glass inside and screw the M48 ring

  6. :

    Hi Sam,
    Can you please confirm that the “New EOS-T2 Adapter suitable for all ASI cameras” is designed to work with the “Nikon AI-EOS Adapter” for my ASI1600MC & Nikon Lens? Camera Lens can reach infinity focus without other modification?

    • Sam Wen


      yes, the EOS-T2 is adjustable for nearly 10mm

  7. :

    Can you please tell me the overall length of this product at the maximum and minimum back focus positions

    • Sam Wen


      it’s suitable for camera whose back focus distance is around 12-20mm

  8. :

    Hi. Is there a way to mount this on a dovetail etc? I.e. does it accept some sort of screw or similar? I see a silver part on one side, but I can’t figure out what it is, it doesn’t quite look like a screw.

    • Sam Wen


      why mount this adapter? you can mount the camera

  9. :

    Is where any way to use this adapter with 1,25″ filters?

  10. :

    Would you consider offering an additional camera side piece with a C-mount thread (1″-32tpi) and 1.25″ filter holder? A T->C adapter won’t work as it becomes too long to focus. Lot’s of folks out there would LOVE to have this to use with their C & CS mount cameras and NV gear! It would also work with your Nikon lens adapter. Thanks!

    • Sam Wen


      I think there is already such C-Nikon adapter in market, you can search on Ebay

  11. :

    Actually, thinking about the above idea, you could leave the 48mm filter adapter as-is, and use a step down ring if you want to use a 1.25″ filter.

  12. :

    I have 2 questions about this product:
    1) Does it support asi178 and asi120?
    2) Can I insert other 2″ filters, like H-alpha filter?

    • Sam Wen


      yes to both questions

  13. :

    Showing as out of stock. When do you expect to have more?

    • Sean Wang


      It will avaliable in two weeks.

  14. :

    Hi Sam,

    the flange focal distance of the Canon EF mount is 44.0 mm, the distance between the EF flange of the adapter to the T-mount flange of the adapter is 26 mm to 33 mm. Shouldn’t the camera then have a back focus distance of 11.0 mm to 18.0 mm?

    Kind regards


    • Sean Wang


      yes, for exemple. 1600mm-c have 6.5mm back focus, but it have a 11mm T2 ring can be uesd to extend the back focus length to 17.5mm.

  15. :

    Can I use this adapter with your EFW 7×36?
