EF & EFS objectives

Post by greg22 » Mon Feb 10, 2020 12:21 am


Is it possible with this adapter to use EF and EFS objectives?
In my Canon camera I use these two versions.
Therefore I would like to use also at my ASI 294 MC pro.
Is that possible with this adapter?

And how is that with my ZWO OAG with ASI 290MM Mini.
Can I continue using it with the adapter and Canon lenses?

Thanks a lot

If you use this adapter there is no place for OAG.
