This is a cross-post from another thread, but I'd love to hear more opions from anyone not following that thread

So I have to admit that I've been giving an A7 cameras more and more thought. I still have my gripes with the lack of good affordable native lenses and some of Sony's wonky software decisions (like auto-ISO limitations), but as I mainly use legacy glass anyway, it's still compelling me.
I love my 6D, but I simply don't use it now that I have my Fuji entirely because of the size. I can bring my X-E1 and 3-4 lenses and it'll still weigh less than my 6D and one or two lenses and it's a whole lot less cumbersome and eye-catching for candid work (which is what I mostly enjoy).
My only fears for letting go of the 6D are that I'll miss the OVF for low light shooting, the awesome high ISO capability and it's ergonomics and lens potential (though I can still use those lenses with the Sony, the AF will be pretty much worthless).
I started by eyeing the A7, but then it seemed most reviews said that the A7r was better in pretty much every single way... then I mad the mistake of looking at the "s" and apparently it goes even further by making the EVF far more useful in low light (one of my biggest concerns) and by adding a silent shutter (my biggest concern, to me the A7r's shutter sounds absurdly loud in videos, but I've yet to hear it in person).
So I was hoping some owners could chime in. Is the A7r useful at ISO6400+? I have numerous shots at ISO12800 and up on my 6D which I'd have no issues printing, I'm afraid of losing that capability (I'm sure the A7s would give me the same ability). Is the shutter as loud as it seems? Will everyone in the room turn their head when it goes off? And is the A7s's normal shutter any quieter?
I know I had other concerns and questions... but that's all that's coming to mind right now. The reason all this started cropping up is that I have no quarrels buying used gear and right now the 6D and A7r are nearly the same price in the used market, so I could make almost a direct trade... the A7s on the other hand would cost me a good chunk of change so I want to be sure before I go any further... also, if any A7 users live in the DC area I'd love to meet up so I can see one and maybe shoot with it a bit in person!

if you're not into landscapes, stick the A7s/A7. The shutter lag of the A7r is it's biggest handicap IMO, for candids or anything with people. It's a real shame, that this handicap exist. 0.060 vs 0.160 is pretty damn significant lag.
Auto iso implementation. Not an issue with manual adapted lenses, you can shoot shutter priority, and compensation at the top dial.
with native lenses, you can shoot manual with auto iso and compensation.... in canonland, only a 1Dx offers.
For adapted lenses, sony beats fuji hands down. no need for speedboosters, only dummy adapters, and basically any lens would work.
High ISO, I would put my personal comfort level of the 6D to 25600 and A7r to 12800, even though I would rank the 6D 1/2 stop better in high ISO. Difference exists, but not too bad. A7s looks like a full stop better than the 6D, but that's only from the samples I've seen. The A7r is pretty good at high ISO even if it's a landscape machine. Noticeably better than my older 5D2, maybe even a little better than the 5D3.
ergonomics, the camera is a bit small. You can use a cheapo L bracket to beef it up, or a half case.
Shutter of the A7r is annoyingly loud. Sounds like older DSLR's, kind like the old 5Dc. Sony definitely does things differently, but dedicated dials for shutter/iso/aperture, make the system golden. It's just something I've always wanted from canon, but never got. Same thing with Autoiso in manual mode, although only really useful with native lenses.
I have a LARGE set of old manual adapted lenses, and the sony has been an absolute joy for that. adapters about 11 bux for Fotga and get the job done. REALLY love the older 135/2, 85/1.2, 50/1.2. Those three cost me as much as my EF 50L and 135L, but I really have no regrets making the switch to the MF adapted versions. I still have a 70-200ii for really fast action, but honestly hardly ever used (as expected). Seems kinda frivolous swapping for full manual lenses that were pretty expensive, but they were significantly smaller. The FDn 50 1.2 is toylike in size. It's tiny compared to the EF 50 1.2 and you'de be hard pressed to tell the IQ difference, and quite frankly even the FDn 50 1.4 was pretty good (still have that lens as well). 28 2.8 is with me all the time, weighs about as much as the 40 pancake, gives me wide angle in a pinch. At the end of the day, I'm extremely happy with my set of manual lenses. I honestly could not even think about shooting these lenses a year ago.... now I've sold a few of my EF lenses in favor.
if those 1.2 glass are still too heavy, you can get smaller counterparts for cheap. 50mm F1.4 I got was $90 and very very good (90% the level of the 1.2), 135F2.8 only $80, 28mm, $30? The slower versions are very small and light.
