Here are some thoughts about the A7r, without hyperbole.
Before buying an A7r, I defined my requirements and did due diligence. The due diligence process took place over a six-month period after the camera was released.
As a long-time professional, that is how I approach major equipment purchases. As distinguished from my hobbyist side, where I make impulse buys of all sorts of "obsolete" lenses.
My remaining professional level work is tripod-mounted landscape photography with large prints as the finished product. All other work is entirely casual. I don't really care about AF, burst rate, etc. etc. I do need a high-quality sensor and the ability to focus manually with very wide lenses in dim light.
My due diligence included reading all available independent reviews and many user reports. In particular, I researched reports on the performance of specific adapted lenses on the A7r. My conclusion was that many of my manual focus lenses would work well on the A7r, but I would need a major upgrade on lenses wider than 28mm. I then bought a Leica adapter and went to a friendly local store where I made test shots with my trickiest lens, a pre-aspherical Leica Summilux 35/1.4. I also verified that there was nothing fatally nasty about the camera's handling, controls and viewfinder. When I examined the RAW files they met my expectations as a member of the Ancient and Honourable Order of Pixel Peepers. A month after I bought the camera, the 16-35 became available locally and, as planned, I bought one.
I'm very happy with the technical quality of my results over the last two years, and have found the camera pleasant to use within my personal parameters. As I've said elsewhere, I wouldn't recommend the A7r as a generalist photographic tool. The K-1 at first glance, and several established cameras from other brands, are better. However, in terms of my personal requirements in my dotage the A7r has been a great success.

The "performance" is not at top-of-the-line Nikon or Canon levels in many ways. This was well-known soon after release. When I researched the A7r, I concluded that for my work an approach similar to my use of medium format film cameras would be appropriate. That has proven to be the case. Fine by me. I'm not a spray and pray type.
I find the EVF and focus magnification extremely useful in my most challenging conditions.

It was widely acknowledged soon after release that the AF performance of the A7r was not brilliant. Sort of average by mirrorless standards at that point. Doesn't matter to me. I've never even bothered to try continuous AF on the thing.
I've done some very casual low-light AF work using adapted A-mount lenses. The performance was adequate. There are issues using native e-mount lenses in low light because they tend to focus stopped down, and some menu diving may be required to overcome this.

"Ergonomics" is a matter of personal preference, experience and flexibility.
I had no problem customizing the interface to meet my needs. Thousands of other people are using the camera happily. In terms of size/weight, I view the camera as modular. I use the battery grip with large lenses. If I want to go compact, I take the grip off and use my Leica lenses. This was expected, which is why I bought the grip as a package with the camera.
Originally posted by HopelessTogger The lossy RAW ain't good either
Lossy RAW compression strikes me as a rather goofy idea. I've no idea why Sony came up with it. That being said, I've seen no evidence of any problems in most conditions. I have seen a few examples of possible artifacts under extreme conditions. It's only a problem when it's a problem, and that is rare.
You left out shutter vibration, which is at a level that I find very weird in a mirrorless camera. On the other hand, I was prepared for it and had no problem developing simple workarounds for my applications. I can see where it could be a pain in the butt in a fairly narrow range of circumstances.
HopelessTogger, I wish you better luck with the K-1.

Please note that in the comment your are "quoting" I suggested
sensible research. There was no mention of 6 months of intensive research or of listing all sources.
I suppose indulging in hyperbole could be interpreted as digging yourself a hole.
