ZWO to EOS adapter for use with Filter Wheel
This is a well made adapter. It is strong and it fits well. My problem with it is that I could not obtain infinity focus. I have everything as short as possible: EOS lens > Adapter > EFW > Camera, but the image train is still too long to reach infinity focus. My only hope to use filters is to screw them inside the adapter (it is threaded for a 2" filter) to be mounted internally - which was a good thing to incorporate in the design.
I used this to attach a Pentax 300mm lens to my ZWO ASI183MC camera. Needed a Pentax to Canon adapter but they are available. I believe this is made to use a spacer or filter wheel between the lens and ASI camera. But since the Pentax lens would focus out enough I did not need one.
