I had put in an order to B&H for the R5 not expecting it to come anytime soon given a lot of people were still waiting for it with their orders from Late July. I ordered it mid Sept and lo and behold I received it in about 10 days. Not complaining though 
I also ordered the RF-EF adapter (the plain one) which was also back ordered everywhere and received that as well a day after the R5. I subsequently also ordered the RF 24-105L. The plan is to use this combo for bulk of my shooting and use the other lenses with the adapter. I also ordered the Sunway Photo L bracket since was available and both RRS and Kirk were backordered. I am happy with all the choices so far. Unlike both RRS and Kirk, the Sunway Photo is a two piece unit and the the "L" can be removed if needed.
First impressions
The body felt good in the hands and is lighter than the 5DsR, not by a lot but still lighter. The EVF is nice and bright and I really like it. It was one of the things I wasn't sure about since my early experience with EVFs were not that great. This one didn't disappoint at all. One does notice that the lag when you pan - the sports shooters will notice it more. There is an option to increase the refresh rate but that consumes more battery. For my use it is a non issue since I primarily shoot landscape and nature and occasionally family. The EVF can be configured to show everything that one can on the rear LCD including the histogram, level and settings which is really nice.
Controls are different from the 5 series DSLRs which is something I got used to from many years of using it. It will take some time to adjust the muscle memory to adapt to it. The top LCD is smaller than the one in the DSLR, however it does show the mode(Av/Tv etc.) even when the camera is off.
IBIS is very good. I was able to hand hold and get pretty stable images at 1/5s (coupled with the lens IS).
The LCD is articulating and this is something I am not sure I like since with the L bracket its movement is both restricted and one needs to be careful that the LCD won't get accidently damaged. Without the L bracket the movement is not much of an issue.
The DR is significantly better than the 5DsR and it is one of the reasons I made the jump. I was easily able to push 2-3 stops in low light without the image falling apart. One thing I haven't yet played with is very high ISO. Based on what I have seen reported that is significantly improved as well.
That is it for now. Bottom line I am pretty happy with it. I plan to keep the 5DsR as a second body and in good light I can keep different lens mounted and not have to switch lenses in the field as much.
Happy to answer any questions anyone has.
