Re: Well, I jumped...
Thanks for the post. I've been interested in the a7r iii as well. I just watched a video recently of eye AF with canon lenses and the sigma adapter (I believe) and couldn't believe how quick and reliable it seemed to be, and it wasn't even well lit.
Although, I'm not referring to the a7r iii but instead the d810, which from my understanding have very similar dynamic range I was blown away. I was playing with the raw files from a friend who just purchased one, (switching from canon) and there was a shot that was very poorly exposed. Now, no one should realistically be screwing up a shot by 5 stops and the +100 shadows I pushed it in lighteroom, but it was so surprising how little noise and how usable the image was. I can't speak for the 5div, but I feel my 5d3/1dx wouldn't be able to compare with half the pushing i did to the d810 file. Although that isn't enough for me swap systems, it was a big surprise and I can understand why many seem to be making a big deal of the Dr of the Sony Nikon cameras.

I did a LOT of research and was fortunate to borrow an a7rII to try. With that done, I purchased the a7rIII, metabones V adapter and the Sony FE 85/1.8 from BHphoto. They arrived Friday at 5pm and I threw them in the house before taking a flight out of town. Returned home Sunday at 1am, charged battery and crashed. Today, I've been playing with menus and the camera.
Body:
For good and bad, it is smaller. I put my hand strap on it which made it instantly more comfortable and will buy the RRS L plate which adds to the bottom. The camera is quite comfortable to hold and handle in landscape/horizontal orientation. I do find the finger placement a bit awkward in portrait/verticle but am quickly getting used to it. Battery life has been solid. Body is very customizable which is great and a pleasant change from Canon's 5DmkIII that I had been using for about 4 years.
The body is lighter which doesn't seem important until I put the Canon 24-105 on via the Metabones adapter and went out for some test shots. Slung the camera over my neck/shoulder as I would the 5D and was pleasantly surprised at the lack of pressure over the clavicle area. It felt much lighter and less of something I was aware of carrying.
Autofocus
I have to say, the biggest surprise to me is EyeAF. I didn't know much about it before and started reading about as I researched the Sony. Still, I didn't get how powerful it was. Simply put, the camera finds your subject's eye and nails focus Every Single Time. That's good in and of itself but it also means that you no longer need to compose based on lining up a red square with your subject. You are now free to compose your shot however you like and essentially ignore the person/focus while knowing their eye will be nailed. Shot the kids tonight as we lit candles for Hanukkah and the results were awesome.
Lenses
The 85/1.8 is really nice and I will happily give up my Canon 100/2 for it. All of my Canon lenses work with the Sony (which is really amazing). Still haven't pushed any lenses to test autofocus speed as I'm trying to get used to the 85 for a better sense of native vs adapted lenses. I can see myself dumping the Canon 17-40/4, 24-105/4 and 70-200/4 for the Sony 12-24/4, 24-105/4 and 100-400 though.
Software
The menu system is LONG and needlessly confusing at times but makes the camera ridiculously customizable.
Files
Processing in LR Classic 7.1. The files actually look great on the Sony LCD screen and in LR before Adobe processes the preview files. Not sure what Adobe is doing but the files are much flatter than the Canon ones. They also have a ridiculous amount of leeway when it comes to pushing exposure and shadows. I read this before but it's very different to actually work with the files and see how easy they are to work with without 'falling apart' like the Canon ones are prone to do.
It's only been a day of use but I really am pleased with the Sony. This is their third iteration of the a7r series which feels like a mature product now (just like the Canon 5DmkIII did when I bought it). Between the improved sensor, customizability and eyeAF, it really is a marked improvement over the Canon I had and the ones on offer now.
I realize this is a Canon forum and I may get pummeled for this but thought it worth circling back and reporting my experience so far.
