thanks, serhan, for that link. The reviewer clearly knows nothing about Sony cameras so is a good guinea pig from the Canon world I guess. There will be entertaining and large wake up calls for such people in coming months.
'I want to know what the dynamic range actually is and how it’s performing in different scenarios.'
Mate, visit DxO and take a look at Sony FF equipped camera results, short answer is this: the last generation ones were 2.6 stops better than the Canon most people use, the 5D3.
That much extra DR buys a lot of extra tonal and colour gradation, not to mention captures almost all the bright skies and deep shadows. All very important for landscape work, where low ISO is the norm.

The reviewer had two Canon TS-E lenses mounted on the A7R but somehow forgot to take pictures with it?
I'm very curious to see how the corners hold up with the metabones adapter...

He had no RAW support and was probably in a shop somewhere looking more at putting it all together...it would indeed be good to see either TSE results. soon hopefully, what about that 22-24 Oct show in the US? It is promising they let him take some shots in Aust.
Huff has some info from that show - Sony saw him coming however and would not let him stick an SD card in it, lol. I love the story about the Zeiss woman who wanted Huff to put the Otus on the a7r.
'I HEARD MUMBLINGS…Sony was telling Zeiss..MAKE THIS FOR FE MOUNT!' haha.

From my reading AF speed will satisfy most users for most uses. They kind of need that as Nikon has a good system and also to push the majority of users into their FE lenses.
p.37 #6 · Official: Sony A7 and A7R Fullframe Mirrorless
I've read AF is faster than NEX-7. But having not used an NEX-7 extensively that's not a useful frame of reference for me.
Then again I doubt AF speed will be much of a factor for early adopters since most of them will be legacy lens users and thus manual focus champs (let's not flatter the Canon EF + metabones combo as AF will be molasses slow with that and it might as well be manual focus).

Yohan, people will come everywhere - NEX, ESO, F mount, m43 and will want to do everything with it. Only those who value really snappy AF will not be happy enough.
It's Sony's task to persuade them to buy into the native lenses and many manual focus lens users will do just that. Apparently the Canon adapter is 'as fast as LV', is that any good to anyone? I don't know. I looked up their page and full function support for the EOS range is patchy by the looks of it.

Most people here go for the A7R, but I still can't choose.
I don't like that both models differ that much. The cheaper A7 has: electronic first curtain shutter, faster flash sync speed, better faster PDAF+CDAF,... Which can be important features for some.
Argh.

Thank you, cool review. RAW's available for download
I downloaded the A7 ISO 12,800 raw and compared it to one of my D800 raws, both with NR disabled and downsampled to the same resolution. For areas of the two images sharing somewhat similar absolute exposures the A7 raw appears to have similar amounts of color noise but less impulse noise. The tightness of the noise grain appears about the same, indicating similar SNR. However the shadow noise on the A7 appears significantly less, implying Sony has been able to increase the High ISO DR vs their previous generation Exmors. Also the A7 doesn't have the magenta amp glow noise that the D600/D800 suffers from - that in itself will be a huge improvement.
Take this all with a grain of salt since I'm comparing two completely different images...but I have spent a lot of time with my High ISO D800 images.

I'm sure you know this, but:
If AF is important to you and you're willing to use native lenses, go with the A7.
If you're a landscape photographer and you print reasonably big, go with the A7r.
If adapting RF wides is important, the jury is still out. Wait until some knowledgeable users post their tests (I think this will be more clear in 1 to 2 weeks).

AF on a7r:
'AF speed with the new 55mm 1.8 Zeiss lens is VERY fast, FASTER then my Nikkor 50mm 1.4 on the D800E.'
'As you probably know a 55mm requires a much higher level of accuracy and has a longer focus throw. The lens feels incredibly solid with a buttery smooth focusing ring, very close in feel to a well-dampened mf ring. Very close indeed. I am impressed (at regular indoor light levels). One has to wait and see how it performs in low light.'

Reports that A7r does better video; apparently fast (lens specific no doubt) AF. What's not to like?

Just processed a few RAW's from Korean review in RPP... The noise can be noticable from ISO100 without any NR, as usual for sony, but the colour resolution very very good and I like this much

Does Sony offer a small RAW file like Canon?
Sony used to offer a larger, uncompressed lossless RAW and a smaller, compressed lossy raw (cRAW). Now all they offer is the small, lossy raw. So, yes, all they offer is a small raw file.

That's not entirely true, as I understand and have experienced it. The a99 does compress RAW if you're in continuous shooting mode. Single shot is still uncompressed.

Thanks for doing this, these are the most interesting samples I've seen yet.
Does anyone else think the low ISO samples are insane? I've got a D600 and a 6D, so I'm used to looking at 24mpx FF, but these look really good.
The ISO 6400 image (the last image of the bicycle) shows a surprising amount of color noise, so not sure what to think about that.

Put my pre-order in on Tuesday for an A7 and I am sooooo pumped! Canon 5D will have a new home and the A7, A77, and NEX-6 will be my go to arsenal. Full Sony!!! Yeah!
