Most here might be RAW shooters, but it's interesting to note plenty of confirmation from reviewers that Sony have finally got JPEGs down pat. This from IR:
'Both the Sony A7R and A7 show a fantastic amount of high-contrast detail all the way from ISO 100 to ISO 6400. There is also a difference in the contrast levels of the in-camera JPEG across these different models and brands.
The 5D Mark III looks quite similar to the two new Sony cameras here at ISO 100 and 1600. At the higher ISO levels, the Sony A7R is pretty well free of any high ISO noise issues (as is the A7 and 5D Mark III to a bit lesser degree) whereas we see the D800E having minor issues with chroma noise.'

Any idea if there are adapters being made that allow you to control either the EOS lenses (aperture and autofocus) or those of nikon (aperture and autofocus).. Also M adapters (which I know exist). Although I also think the EOS adapter exists right, since I've seen the A7r with Otus (but I'm not sure if they had aperture control in the lens, or via the adapter).
Reason I ask, I'm looking to get an A7r so I can use the following lenses:
(I have a Leica, and Nikons and Canons, and Sony alpha, so wondered if I could do a one body solution?)
24-70 ZA
50 Sonar ZM
50MPZE or ZF.2
100MPZE or ZF.2
Also, pipe dream, but full contax G2 lens support?

the answer to your question(s) is yes. but...
canon: the metabones mkIII eos to e-mount will give you aperture control, (slow) AF, and IS
leica m: there are numerous adapters including one that allows auto focus magnification when you turn the focus ring as well as reading the 6-bit lens ID and adding it to exif. there are also a number of different adapters with built in helicoids to add close focus capabilities to your m lenses without losing infinity focus. voigtlander recently announced a rather solidly made one.
nikon: you can get a bunch of adapters that don't pass any info or control aperture and you can also get ones designed for g lenses (don't have aperture rings) that contain a lever to move aperture lever. this allows you to control the aperture on g lenses, but you can't tell exactly what aperture you're at.
sony a-mount: sony makes two adapters for a-mount to e-mount that are FF compatible. one has a mirror in it like the a99's to allow fast AF the other doesn't have a mirror and only allows slow AF with some lenses.
contax g: there are number of different adapters that incorporate a geared ring around the adapter that allows you to manual focus the lenses. it's kinda kludgy and nowhere near as nice as a real manual focus ring. there is also this adapter that gives you AF on your contax g lenses, but i hear the AF kinda sucks with most lenses (especially if you stop down). the motor is supposed to improve the manual focus experience with the though.
btw, many of your wide angle rangefinder lenses won't perform as well in the corners as they do on you m camera (color shift and smearing in the corners).

Awesome.. I'll look at all these links when I get home.
Nah, to be honest with you, I am considering selling my whole G2 kit, but if I keep it, it would be nice to use the G lenses on a digital body (for fun more then anything). And as for the Nikon/Canon, I don't care about any of the other lenses aside from the 100 MP and the 50 MP... And again, it would be nice to use M lenses in a pinch, but I have M bodies..
So really the other adapters are more out of curiosity. I'm mainly interested in getting the A7 for the native zeiss lenses, and for the 50/100 MP lenses. With the G lenses as a bonus
One last thing off topic thing, the A99 cannot take Canon or Nikon ZE/ZF.2 lenses right?

you can get a leitax lens conversion kit for ZF lenses that will allow you to mount them on the a99. i'd be tempted to use the ZE lenses on the a7r instead to get all my lenses focusing the right direction if i were you. on the other hand the 100 MP is a pretty decent sized lens, i'm sure it'd balance better on the a99.
btw, it seems the g 16, 21, and 28 will play extremely poorly with the a7(r) sensor. the g45 and g90 should be great though. don't think anybodies tested the g35.

i would call it crunchy. the adapter typically have a break in period after which they loosen up, but they are always uneven in resistance. you can focus more precisely with them then you could with the rings on early AF lenses though. definitely not good for tracking. they turn the wrong direction too... i haven't tried the AF adapter, people tell me improves the manual focus experience. i just took the optical blocks out and stuck them in real helicoids rather than dealing with kludgy adapters.

Care to elaborate on that last sentence? Just curious that's all
The af is not fast, but it works at big apertures w/ 35, 45, 90mm. The manual focus is much better then any manual g adapter, since the focus ring is motorized. So it has very smooth mf turn.

Corner performance on the Nex-5 and 5n was not the greatest and the 35mm G is considered the black sheep of the Contax G primes...
So I dont have too high hopes for the lens on FF....
yeah, i wasn't too fond of it on my NEX-3, but i'm pretty sure it was just the lens not how well it played with the sensor. FF might actually be more forgiving of it's defects (larger pixels and all) if it doesn't have color shift or smearing (which it didn't on my NEX-3). it's a nice small 35/2 though for those who don't need maximal performance.

I'll be trying the g35 when my a7r arrives. It has zero color caste on the NEX-7, unlike the ZMs, but as mentioned is a bit soft in the corners. It may be a sleeper for the FF a7/a7r -- time will tell. Here's the test I did on the NEX-7: FM Forum: G35 on the NEX-7
on the other hand the 100 MP is a pretty decent sized lens, i'm sure it'd balance better on the a99.
