Zvonimir Tosic: First the amazing GX7, now LX100. This is brilliant; real thinking outside the box.
quangzizi, the whole laundry list is useless, as RX100 is a pocket camera while LX100 isn't. If someone wants a copact pocket camera, RX100 wins. Period.
"LX100 is by an order of magnitude *smarter* and more innovative product than any Sony's compact"
How is it more "innovative" than the original 2 year old Rx100 and full -frame RX1? One was a pocket camera with zoom lens and 1" sensor and the other was first full frame compact.
Pana is more similar to Canon G1X series.
AlanG: Clearly Sony sees that one place to attack Canon and Nikon is in the full frame video market.
Nikon has never been in video market. Sony has been in video market before Canon.
WHere is FS7 announcement? That's E-Mount camera
princecody: Also why no Sony E mount Otus?
E-Mount can use all other mount lenses with adapter.. There is no AF on the lense anyway.
Bob Meyer: You comment that:
the a7S's low-light advantage is less clear-cut when shooting VIDEO. The low-light advantage will only be available when working with shallower depth-of-field than the GH4 can offer (which may be desirable, depending on what you want to achieve). However, if your composition requires a certain depth-of-field, the sensor size advantage is lost as soon as you match the two.
Both cameras have sensors close enough to the state-of-the-art that there's no way the GH4 can make up for the difference in sensor size, which should give the Sony a 2EV advantage, in low light.
The first applies to still photography as much as video, and the second ignores DOF . If you need more DOF, you need to stop the lens on the FF camera down two stops, exactly matching the light falling on the smaller 4/s sensor. Sometimes a FF camera's ability to generate shallow DOF is an advantage, sometimes not.
Why re we talking about Hollywood movies with milion dollars lighting budget?
There are other professional independent filmmakers and journalists who might have to shoot in available light. DOF is flexible and A7s clearly would be a better camera to shoot in lowlight situations.
GoneMirrorless: Scratching head. Why compare when they are so different???GH4 $1000 less and has 4K option no extras neededA7s $1000 more needs $2000 option for 4K, undisputed low light king, FF
Where are the real reviews? I wanted to read about the GH4 - the one I can afford - and there is only this which is not helpful to those with an under $2000 budget.
I read GH4 focuses like a top DLSR -big advance for mirrorless- but this review has squat about that.
They aren't that different. Both are DSLR-shaped cameras that capture professional quality video. Anyone who is primarily interested in video has an interest in both; so it's a valid comparison.
DOF is flexible and it's not the case that you need exact matching DOF to shoot the scene. So, no, you aren't losing high ISO advantage. If it's a lowlight scene (evening beach, sky, stars, indoor concert, wedding, church, etc) and you are shooting wide open anyway, A7s has the advantage.
CaPi: I am still unsure wether these two really can compare. What are we going for here? Will we learn if sensor size has become unimportant.?I wouldnt think so. hm. Any ideas?
They are comparable as two video cameras that also take still images, as both are primarily targeted towards video shooters.
A77 II didn't make any list?
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.
