It's primarily a still camera -- and will sell very well among sports photographers, a companion to 1Dx. Prosumers Video market is tiny, especially when there are dedicated/cheap camcorders anyway.
Even GH4 isn't that big seller-- that should tell us its pretty tiny market segment. If anyone doubts that look at number of average daily users for GH2 and GH3

Incidentally, I just watched an in-depth presentation on camera ergonomics (presented by Sony about a year ago) that is worth a look:
This is interesting as FS7 seems to inspired by this talk. Everything in FS7, including shape and size of handgrip, is exactly copied from this talk.

The D5200's sensor, and presumably all 24mp APS-C sensors used by Nikon thereafter, come from Toshiba. Go here for confirmation:
Also presumably, the only non-Toshiba 24mp APS-C sensor used by Nikon is the one on the D3200, which is actually a Nikon sensor:
That just means the sensor was made in Toshiba factory. It can still be exact same Sony/Nikon sensor made in Toshiba factory due full capacity overload in regular Sony factory that was making the sensor. Doesn't prove shit.
Toshiba and Sony share resources like that. That's nothing new.

Some of these questions are silly.
"10) The Nikon Df shared an almost identical aesthetic design to the old Nikon FM film camera, yet despite being a digital body with a very high price it is bigger and has more plastic on it. Why?"
Bigger? Isn't it obvious why? A digital sensor is much thicker than film and produces heat, unlike film. Why won't it be bigger?
"7) The sensor in the D5200 was manufactured by Sony and the sensor in the D5300 had Toshiba markings despite being almost identical in terms of performance and design. Was this a Nikon designed sensor, with the manufacturing outsourced to other companies?"
​Probably because it's just the same Sony/Nikon sensor manufactured in Toshiba factory. Sony and Toshiba do share resources like manufacturing factories.

Is that the camera? (via SAR) Claims to have F55 sensor
-
"Annoying" is the fact that the a5100 gets full pixel readout and XAVC-S and the higher a6000 released four months earlier is stuck with AVCHD, not to mention higher end cameras like the FS700. So essentially, the low end consumer a5100 probably has better video than pro cameras such as the FS100 or FS700 which are not that old.
Where do you get A5100 has full sensor readout? It has XAVC, yes, but it's newer model, but I haven't seen reference to full sensor readout without line skipping.

So they make pay 12 000 USD for 1 line of text...
What a strange world we live in..No, as F55 sensor is different too: Global shutter on FF

<all cameras below have pro audio quality. Listing SNR & noise floor would be helpful)F65 - 3.9K (8K sensor with a few tricks, not true 4K) - 16-bit RAW
I assume you meant 8K sensor with a few tricks, not true 8K Of course F65 does true 4K

Not sure if this was posted
A7s and GH4 shootout
-
A7s in camera HD is cleaner than GH4 with no aliasing while GH4 has aliasing
-
Three different video shot in different conditions, lighting, graded totally differently doesn't prove anything how the image quality compares to each other.
DPReview now does studio still shot taken from video. That will really show how D810 does in capturing detail and moire compared to others.
-
Why would anyone shoot at iso 12,800? It's totally unusable for any prosumer use, judging by the look of this video.
..iso 12,800 is absolutely fine A7s. This video is in crop mode with line skipping. 24-30 fps iso 12,800 is just fine.
-
Okay, Andrew, you sold me on the Sony A7S, but what do you think the odds are that they'll have internal 4K by next year, and at what price point?
Then you can sell A7s on used market and buy a new one :) That's an year without a FF camera.
I predict the next year will be F60 with FF 12 MP sensor, same body as F55, and with global shutter.
-
What's interesting is that in APSC mode there is no change. It's all sharp from 24-60p
-
(Look at the video page to see links to his tests at other frame rates and APS-C mode)
60p does indeed look better. So the simple solution is just to film everything at that rate then?
Doesn't 60p skip lines?
The rolling shutter on A7s looks to be comparable to GH3 in APSC mode.
-
F55 has global shutter, too
-
The dynamic range with SLog will totally blow the crap out of GH4, as well as low light performance, probably 4 stop advantage in video mode.
I would like to see 5D III raw vs A7s Slog
Even Alexa has rolling shutter.

Raw. Dxomark measures sensor data before demosaicing. I think you'll find examples online where the A7R is *slightly* worse.
raw has yet to undergo demosaicing and that's same for all raw. That's why they are raw. A raw file is developed on computer. Dxomark are comparing raw, not jpegs
-
"No way in hell"? Is this before or after the Sony fully read sensor overheats, or a light drizzle shorts it out, or the battery goes dead? :D
The Sony's are great if you can keep them running.

According to the specs, the battery life for video on A7s is around 90 min. . This is same as Black magic camera where battery isn't even swabable. 5D III averages around 90 minutes per battery for video too

And obviously 11bit raw is a bummer, why would you go for 36MP into medium format territory but then just use 11bit cooked raws. They had to save bandwidth somewhere to keep down the processor need (It just takes 300 pictures with one baterry...)
It's 14-bit raw with visually lossless compression that does not effect image quality, as shown by dxomark. There is no difference in raw image quality between A7R and D800
Red Dragon scores higher than both with compressed raw. It's a big plus.
"36MP "
MP and raw bit has no relation. In fact if anything higher MP sensor can use lowers bits due to smaller pixels that would require less bits due to more noise that visually lossless compression could ignore without any negative con on image quality
-
Possibly due different algorithms? I find the A7R images slightly worse than the D800's.
Are they jpegs or raw? Dxomark couldn't find these "differences"
-
Purely from a stills perspective:
1. Nikon has a proper lens lineup, with a much better AF system.
2. Nikon 14 bit RAW loseless vs some weird semi-lossy RAW format Sony uses
3. Much better ergonomics on the Nikon.
Red seems to do fine with compressed raw. Compressed raw is actually better as it has no visible impact on image quality but yet procuces smaller files., as shown by paper here http://theory.uchicago.edu/~ejm/pix/20d/tests/noise/noise-p3.html
The right here is " "visually lossless"" as the "data" that is removed has no visual information. (it's random noise)
