For a small lens, Novoflex or Rayqual. For a big lens, Metabones. I assume you know that if you don't have the aperture ring on the lens, you don't have precise aperture control with these adapters.

How would you overcome this limitation.
Thanks
Unfortunately, we can't at the moment. No one has worked out the F mount protocol yet (probably because the patent is still in effect). Canon EF mount protocol patent has already expired so that's why you see a bunch of "smart" Canon EF to E adapters, which would allow you to control the aperture on the body. So either you stick Nikon lenses with aperture ring or you buy the Canon/Sony equivalent.
Edit: I should elaborate more. By precise control, I meant you can't just set the lens at f/5.6; you can still stop the lens down. You can find out about the aperture value on the adapter by trial and error but it will change for a different lens.

Smart move to fit a 1/8000s pro level shutter for the intended audience to head off the RX1 complaints of 'where is the ND filter' when using f1.4 optics.
for carsten and Vern, a piece my MR who got a play pre-release:
'For some photographers (myself included) putting Leica M mount lenses on the Sony A7R may be reason enough to break out a bottle of Veuve Cliquot champagne and celebrate. Using an M to E adapter (I have a Metabones), virtually every Leica M lenses that I own works well on the A7R. Some of the ultra-wide and very wides do vignette, so be aware of this. There is no software correction for this, because we're mixing and matching. With other systems where the lens and camera are from the same company there's a lot of magic that can be done in firmware.
I had neither the time nor the full selection of lenses to test in detail what works and what doesn't, but I think it fair to say that most retrofocus design Leica M lenses will work on the A7R. When you consider that this camera has a high resolution EVF, focus peaking, intelligent Auto-ISO – so manual aperture lenses can be used in a semi-automated manner, and of course a 36 Megapixel sensor, this is hot stuff indeed.
In my opinion, anyone who owns a set of (or even a few) high quality M series Leica optics should seriously look at the Sony A7R. They make for a killer combination, and the Sony costs less then a third of an M240 camera. Just test that the lenses that you plan on using work as you expect before taking the plunge.'
I also loved the beardy hipster in the SAR video who seemed to be experiencing focus magnification for the first time, reading fine print on a distant sign...he seemed not to believe what he was seeing...priceless....Show more →

I think you might want to watch that again. He does this stuff every week and knows live view and focus magnification. He was marvelling at the amount of detail rendered, not the magnification.
About LL and the Leica M lenses, that sounds promising, but to be honest, I don't believe it. How would those lenses need correction on the Leica M series cameras but not on the Sony? Makes no sense. Unless Sony has really, finally, absolutely perfectly solved the problem of light impinging from different directions. Which I somehow doubt. I will wait for the more critical tests. Keep in mind that no one has access to raw yet, AFAIK.

NEX-VG900 is here for some time, and Leica M lens on that are usable. I didnt see any color shift. And it doesnt seem blurry in corners either.
My conclusion for now is that Leica M lenses will be most likely very usable on A7 or A7r. Honestly I care more about SLR lens being usable. Leica M are best there is, but in same time most expensive..
Considering image samples on web now (dunno if those are final versions), JPG engine is set to "destroy detail" at any ISO. And even through that bit heavy handed denoise is noise creeping out..
So if Im worried about something, its that they will be bit noisy.

I think he had a 50 Lux on the camera. Are you saying that you don't believe any RF lenses are going to work well on the camera or just the wides?
Personally, I think many of the wides will work well, but I have no doubt that longer focal length RF lenses will be awesome on this camera.
Mainly the wides. I am sure that *some* will work well, and the prices of those will rise rapidly on the used market, but I do also believe that there is no perfect solution here, also not from Sony.
But yes, actually I am slightly afraid that the benefits the wides get from the offset lenses will be bought at the cost of slightly worse performance for normal lenses.

One thing I see about the A7R is that SOOC shots may be better than D800E. D800E uses an extra filter to cancel the effects of the AA filter, so actually has a thick glass filter in the OLP. The Sony does not resort to this approach and leaves the AA filter out altogether. I would expect this to improve detail and sharpness a tiny amount. Will be looking forward to A7R vs D800E vs 645D comparisons ASAP. I also wonder if Sony have been able to make any improvements to the sensor since it was released nearly 2 years ago on D800?
I'd love to see how my 24 TS-E II and 24-70 II perform along with some Zeiss glass.

The world will be the same in that we'll have lots of posters here saying that they don't need 56 MP since 36 MP is enough. Others will say that 36 MP is the "sweet spot" for FF sensors.
Ha. I remember when people used to say that "12mp is the sweet spot." And of course the die-hard Canonites are right now saying "22mp is the sweet spot."
Of course, the other thing to consider when Canon or Nikon come out with their 50mp DSLRs, what is the price point going to be? I'm willing to bet it will be a little higher for Nikon, and a lot higher for Canon.

In theory yes, but given the much larger register distance of Nikkor F lenses, I am not sure this will be detectable. I think the differences in colour will be the most noticeable thing, and perhaps a slight improvement in ISO performance will be second. I doubt there will be anything else of consequence.

....Rational me says: More MP means nothing to me...I've been shooting with 16MP sensors for 4 years and have never really wanted for more resolution. DR is also a minimal increase. I've pulled absolutely insane shadows and highlights out of my Fuji files, to a point where I almost never shoot HDR any more because the pulled and pushed single file ends up looking better than a 5 stop bracketed HDR. I feel no real need for an extra stop of DR. Tonality...Fuji's tonality is pretty darn good. Is the A7 better? Yeah, probably a little, but not THAT much. Well-behaved Bayer? You have a point, though with C1, I almost never have an issue with X-Trans, even with foliage heavy scenes. I'm sure the 55/1.8 is sharper at the edges than the 35/1.4. But again, $1400 sharper? That's the kicker. Do I WANT the A7 with 55/1.8? Yes...yes I do. Does it make SENSE for me to spend the money on it?
This has nothing to do with being rational, nor should it, in my view. My wife's Mini Cooper S probably wasn't a very rational purchase decision, but its the must fun I've had behind the wheel since high school.
I don't crave the A7 for better resolution or more MP - my X-E1 and OM-D both do fine in that department for my uses.
I want the A7 for 2 reasons:
1. That FF look. I don't care how you define it, but you can't deny it.
2. To play with a bunch of old manual lenses on a FF sensor.
Much as I try I can't get this look out of my X-E1 or my OM-D.....there is something about a bigger sensor.....

'amount of detail rendered'
You do know focus mag works before and after the shot is taken, exact same mechanism, but with finer gradation and more range for revie. You get 11.7x with the a99, so 35mm becomes 410mm and so on, even a hard to focus 21mm becomes 245mm of mag...he also did not like the battery door not being sealed, but I have come across others who feel this is a better approach (seals inside instead, bottom panel) and one they take elsewhere, as in the a99.
But, I get phased by anyone theatrically waving a camera around one-handed as they talk - the very antithesis of a photographer...more showman than photographer maybe. At least we know the grip works well, I suppose.
Another clever move by Sony is to retain the RX1 status as the supreme stealth camera, courtesy of the super quiet leaf shutter. They have a development pathway ahead of that model also, for this reason.
Talk of all RF lenses being problematic on the A7r is wildly exaggerated.

michael, what it is was well described by theSuede recently - a 'relaxed draw'. It's an acquired visual skill to see it and many never do, or never admit to it.
Definition of detail is not crunchy and strained but smoothly rendered, focus fade is elegant, the lens 'tries less hard'. Using car analogies, anything with high horsepower smoothly delivered is quite a similar experience. Subaru make a flat six...give your dog a cuddle for me.
This set of samples, we can see that the Sony A7r gave us the very best picture quality performance, especially the 36.3 million pixels giving us very much detail on the impact, of course, in areas such as ISO 3,200 such circumstances we could see he was very very excellent sense of high performance, which absolutely deserves our approval.
We can see the picture quality of Sony A7 and we are satisfied with the performance of, and to know Sony A7 currently lowest bids but full frame camera , but its picture quality is absolutely no lag, its color, and tolerance are very good for those users who does not pursue the limiting resolution, but A7 does not get left behind A7r.
It looks like they also included the same photos from Sony.jp website.
Leica M are best there is, but in same time most expensive..
