I am not clear on setting the aperture. When you focus do you have to have the lens wide open?

Camera dial needs to be at the widest opening possible.
Nothing changes with lens aperture use as you normally would . So you can focus at working aperture.

What do you mean by camera dial?

The aperture set on the camera needs to be set at f/2.
Actual shooting aperture is set on the lens.

Just ordered one from their own site!
And a c/y - M and an OM - M adapter from K&F concept - always had good luck with these inexpensive adapters that have good geometry, just can use a bit of flocking...
It'll be fun to have AF for using some of my manual lenses in remote mode with the iPad...

With the Nikon-L/M K&F Concept on the TechArt adapter my Noct-Nikkor 58/1.2 lens on the A7r2 can finally reach infinity.

ordered one as well together with recommended CY to M and Leica R to M adapters, and am so excited about focus assist on the Contax CY 100-300.
My hand trembles when trying to focus above 200 with magnification!

That lens is quite heavy though
probably right at the maximum weight for the adapter to handle.

It's actually way passed the suggested limit. (700g)
The lens itself is 925g plus you have to add the weight of two adapters to the mix. I use it and it works perfectly though. All you need to do is support the lens with your hand and let the adapter do the work.

Fred, no physical vignetting even at the long end? I had some issues in that respect with my Canon 70-200mm Mark II.

Well,
After updating the FW I had no battery drain overnight, then let the camera sit until this morning, another 24 hours and now down to 74%.
So it seems that issue is not resolved.

I ordered a contax 100-300 should arrive tomorrow or Monday. Is there a generic tripod ring one can get or do i have to order one of the rings from china/ hong kong..?

If you google it I am sure you will find a match. I just did for my Adaptall 80-20mm F2.8.
A canon ring fits on that one.
A lot of the ring son Ebay are listed in diam in MM. Ended up getting mine from amazon.
Or you can measure your barrel and match it up.
Its probably a common diameter.

You may have to get one from China. Like this one for $16:

I don't use one but it's perhaps a good idea. However, there is no place for a tripod ring on the barrel, except on the front of the lens. Perhaps the best idea for this lens on a tripod is to get a MF adapter with a tripod mount built-in.

Good point to order an adapter with a Tripod mount. Darn.. should have thought of that before ordering the Fotodiox. Just for tripod shooting do not want to tax the weight of the lens on the techart adapter.

Fred and any other Contax 100-300mm owners who have tried on Sony A7RII
The lens is great and when focus is perfect outstanding. Holding the lens--- with prefocus and AF-- so easy to move the focus ring a bit. So i have to adjust how I am holding the lens
at F11--- seems like focus easier to miss. Not sure why.. I need to see how things are set. I do not think the contax focuses as accurately (higher miss rate) compared to the WATE
One other issue i have with the adapter -- is that every once in a while-- the camera dies and I have to switch on and off again to restart.

I see this too. Only three times so far, and while not shooting anything important, but that's definitely one bug they need to squash. It could become a deal breaker very quickly.
