T2 Ring (Canon EOS-RF) allows us to attach our Canon EOS-R series full-frame sensor MILC camera to a telescope or microscope for prime focus photography.
It is important that the telescope side has a T2 thread, which is found on most focusers, adapters, etc. If not, then the appropriate adapter (2"/T2, 1.25"/T2) needs to be purchased.
With the help of a T2 ring + adapter, we can also capture images with our Canon EOS-R camera using a biological or stereo microscope, and we can connect such a camera to many spotting scopes optimized for nature observation with a T2 ring.
