I have this information on Cloudy Nights but thought I would share on here too.I would like to share with everyone a recent project of mine that I believe might be helpful to many others using ASI cameras with Canon lenses. Recently, I designed and 3D printed an adapter that allows me to use my ASI183MC Pro with a Sigma Contemporary 150-600mm f/5.0-6.3 DG OS HSM lens, however, this adapter can also be used to mount other EF mount lenses onto ASI camera bodies as well.
The model and further details are available on thingyverse:https://www.thingive...m/thing:5957183
In the future, I do plan to add electrical POGO pins to this adapter which would allow electronic control of aperture and focus on any lenses which support it, this feature would be very useful as obviously ZWO cameras do not communicate with 3rd party optics in any way. There is already a great amount of resources available online for reverse engineering the Canon EF lens control protocol, and I have already performed some bench testing with an Arduino and an EF 50mm f/1.8 "Nifty Fifty" where I was successfully able to command the autofocus.
