A7s was used to shoot a documentary for Al Jazeera
Philip Bloom is also using A7s/F55 combo to shoot a 13 part documentary (for CNN?) that will be shot in dozens of countries.
andyshon: To me the interesting question is why? Clearly they had the budget to shoot on any camera they chose. So why take the risk of using an unproven system like this?
pkosewski, read the post. It was cameraman decision to use A7s -- not any deal with Chevrolet.
A7s has already been used to shoot a TV documentary before this commercial. Google.
Paul Guba: Oddly it doesn't say why use this camera. With a budget and so many known cameras available why would you choose to experiment on a high budget, high pressure job. Why do I feel like I am not being given the whole story?
Here is the direct quote:
""The problem is not the 4k downscale, the problem is 4:2:0 AVC encoding throws away 90% + of your data. You don't get the benefit of oversampling in the color data. You do get better image resolution and cleaner images with fewer artifacts, but it won't help the color gamut and it doesn't give you more grading room. "
It's not true 10 bit.
You got it from EOSHD, as your link proves it. So I was right, and this claim is not true, as discussed here by pros.

There is no Hollywood movie, a commercial, or TV show that was released in 4K.
Arri Alexa is used to shoot almost all Hollywood movies (not Red cameras) and even that isn't 4K
A7s does do 4K with external recorder, but that is not the selling point. The selling point is that it does best 1080 video (for FF) with best low light (compared to any other camera, no matter what price).
Stop repeating the lie. 4K 8bit 4:2:0 DOES not convert to real 10 bit 1080.
EOSHD is wrong.
"The ugliest 8bit banding is usually in much larger blocks than 4pixels, so rounding down, and even approximating pixels into a 10bit space won't help 8bit banding issues for the most part. Also, it does not increase color accuracy. "
Funny that GH4 internal codec is 8 bit, just as 1DC, C300, C100 ( all thousands of dollars more expensive than A7s), but you are complaining about 8 bit on $2500 consumer camera which still has better 1080 internally (less noise, less moire, more DR) than GH4 1080 internal
Downsampling 8bit 4K does not give you real 10 bit 1080 as discussed here in this thread
EOSHD is wrong.
Lab D, Canon 1DC, C300, C100 are all 8 bit codec. They have been used extensively in professional shoots.
C300 is still Philip Bloom favorite camera ever.
And GH4 does 10 bit with only external recorder (optional), and no such external recorder exists that takes 10 bit HDMI 4K, so it's not if anyone is even shooting with GH4 in 10 bit mode. No one is.
Maybe because they wanted to use a FF sensor camera for whatever reason, right or wrong.
All professional video cameras are super 355, which is close to APSC.
Lab D is a M4/3 tro;ll who used to post as "Everdog". He was banned for using sock puppets. He has a nasty obsession with E-mount and telling people why they are bad.
Codec isn't everything. A7s blows the crap out of GH4 in low light video.
where are studio shots?
Zvonimir Tosic: In how many colours it comes? Just one? Two?It hardy looks like a fashionable item — it only looks like a today's mirrorless camera. Perhaps Sony should make a small lens with some interesting finish that can appeal more to both worlds.Leather grip would be a nice touch too. Also engraved logo, not painted logo; gosh, this looks too harsh.
It's entry level camera -that takes 24 MP pictures with fast AF - not a fashion jewelry.
michael2011: In your RX100III video function review, you guys specifically mentioned full sensor readout and XAVC. Here I see only XAVC. Does this mean A5100 does NOT do full sensor readout?
No, it does not, of that isn't mentioned.
Error: A6000 LCD is not touch enabled
Panasonic made the GH4 larger so it looks like something that is in the FF category. (I said "looks", not "is")
Then Sony went and made the FF smaller!
So what? If WR failed for someone despite correct use, they should make warranty claims to get it fixed for free or get a new body
This does not change the fact that A7s series of cameras are WR according to Sony and official specs
Lab D: About the Sony "weather sealing", there appear to be a lot of threads like this for that body type...

Dr_Jon: I'm assuming the A7s still uses Sony's lossy raw compression that can screw up under some circumstances. That's probably even less desirable in a low-light still camera. Examples:http://diglloyd.com/blog/2014/20140212_2-SonyA7-RawDigger-posterization.html
I don't trust the article. There are many other articles that shows compressed raw has no visible difference.
Dxomark scorres (based on raw) disprove all these " lossy raw compression is bad" claims, so do images in these studio shots.
"The larger sensor of the gm-1 equals out the slower kit-lens. "
No, it does not. The kit lens is slower by 2 stops. The difference (dxomark) in sensor performance is not 2 stops. It's hardly even one stop. So the slower kit lens does not equal out by larger sensor.
