The Extenders attach to the lens, and then the EF to RF adapter connects the extender to the camera. They work fine with my Canon lenses. Just connect it to your lens like usual and put the adapter on to make it fit the camera.

Any idea of Extender with 3rd part lens!

Sigma lists its lenses that are compatible, or need a firmware update. They will work even better then on a DSLR, the EOS R focuses at f/11, so you could use a f/5.6 lens with a 2X TC. Problems with inaccurate autofocus basically go away.

I had my R out last night with my 100-400L. I was hoping to see the comet. Unfortunately, it was overcast. I can autofocus on a star at 400mm, but its best to turn AF off for that situation. If its clear tonight, I'll try again.

It was overcast just in the North - Western part of the sky last evening, just where the comet should have been. I'll be watching again tonight. The forecast is for clear weather in the evening.

Its not for portraits. A 85mm f/2 or f/1.2 is the best, you don't need a TC.
