Thank you for a great review… I noticed the lens adapters are back ordered at Adorama, B&H and others…

That Sony is good as well! I know at least a few people using that setup with the 200-600 as well.

I’d say it will for sure focus noticeably faster in low light compared to the 5D4. Most cameras can focus well in good light. The advantage of this camera is it automatically puts the focus point where you want it (eye or face). It will autofocus with that lens and 2x as well. It will focus at f/11 which is what you’d be at with that combo. CF is bigger than CF express so they aren’t compatible. It does have an SD slot though. You’ll want the much faster CFe card though for video or long bursts of photos (it writes something like 1400MB/s)

Thank you!

Thanks Keith! It sure was, but glad to be back for fall. Hope to see some photos from your R6 soon!

Thanks! You’d need the EF adapter to use your current lenses. There’s one with or without a control ring, and one with drop in filters. I have the control ring one that allows you to add a setting to it- https://adorama.rfvk.net/vBMXv

Would you say that the R5 focuses a lot better than the 5D Mark four using the 100 to 402nd edition lens? Do you have any idea how well it will focus using it for bird flight Photography?
Do you know if it will auto focus using the above Lens and the 2X Tele converter?
I understand there is a CF express card slot. Will a regular CF card worki in there?

Thanks!
