Was able to download the 3840 and 1920 10000kbps MP4 clips if anyone wants to download and look at them. Not too bad. Would love to see the original 50mbps XAVC-S LGOP clips.

bad rolling shutter

amazing low light

In the old days they were shooting " day for night"
Nowadays we will shot "night for day"

Re: New Sony A7s to shoot 4K video
 

Even 204000 iso looks usable with a bit of neatvideo treatment, I guess at that point the camera sees a lot more then what your own eyes can perceive. I want one!

Re: New Sony A7s to shoot 4K video
 

It's funny, when I try to capture a dark scene, I try to capture it as my eyes see it. I really don't see the point in making a night scene look like daylight. But then again I've never understood the obsession on having a camera that can do this.

A clean shot whose brightness is indicative of what you see? That I can see (no pun intended). But making daylight from night? Not so much.

Re: New Sony A7s to shoot 4K video
 

I guess I get the "oh wow" on the high ISO but who wants to shoot anything in light that bad. The jello effect is pretty bad.

Re: New Sony A7s to shoot 4K video
 

About the RS (is posted this also in EosHD):

I noticed also RS when playing with the camera. The video makes the A7s look unusable. But just for your info, attached to this A7s was a 70-200mm lens and it was fully zoomed in on the video above. So who is doing a pan like this at 200mm? I don't. Yes for sports it is the wrong camera, but for filming under controlled situations to do a real estate video for example, this is the perfect camera. I have no idea how the rs will look at a GH4 at 200mm. Maybe it will not be that extrem but it will be there for sure!

On the other side when I compared the noise level between the A7s and the Gh4 there was a difference like night and day between both cameras ;-)

Re: New Sony A7s to shoot 4K video
 

What's potentially really cool for me is with this camera is I can get a usable footage with two of my battery operated k4000s led lights, since I'm a one man show this can really help in certain circumstances. Likewise I could show up at a location with just the camera and the same two led lights and presto, I'm ready to go since I can rely on the camera to get usable footage. No cables, no mass of lighting gear, just two light stands, two k4000 bi-colors and the A7s. I definitely want one, but it all comes down to price. At $3000 I'll probably wait, at $2000 I'll buy, in between I'm not really sure yet.

Re: New Sony A7s to shoot 4K video
 

News crews for one. There are occasions where the use of ANY lighting is out of the question, and if there is a least a little light, this may be an acceptable (and much cheaper!!) alternative to an image intensifier.

Wildlife may be another instance.

Re: New Sony A7s to shoot 4K video
 

In my line of work (weddings) these ridiculously high "clean" iso's are all that matter actually, I very often end up in venues that are candle lit only, it's not a matter of shooting it at a iso so it looks like daytime, it's all about selecting a higher f-stop like f4 or even 5.6 on your camera to have a deeper dof to work with and yet still be able to expose the scene like you would see it with your eyes, it's all about have that playing room with your dof and exposure.

At weddings you don't "light" a scene, you take it as it comes, most dslr's that can do 6400 iso have no other option then shoot at f1.4 when it gets too dark, having the luxury to shoot in the ranges of 100 or 200 thousand iso opens up many more possibilities

Re: New Sony A7s to shoot 4K video
 

The ax100 has the same problem, yet I only have seen the issue once where there was faster panning when following a moving train. If you know here the RS can ruin your image you can shoot accordingly and nobody will ever notice. Just don't use it as a sports camera :)

Re: New Sony A7s to shoot 4K video
 

OK I get it. I understand event shooters can use the extra stops. I would prefer less RS than night vision.

Re: New Sony A7s to shoot 4K video
 

Event shooters will be hampered by the 30 minutes video limit, even outside of the EU.

Re: New Sony A7s to shoot 4K video
 

Uh oh. There is a 30 minute limit in the US? Where did you see this?

Re: New Sony A7s to shoot 4K video
 

"Event shooters will be hampered by the 30 minutes video limit, even outside of the EU"

Specs on the Sony US website do not mention any recording time limit at all.
(check out 1st link in this thread).

Cheers,

Re: New Sony A7s to shoot 4K video
 

The 30 minute limit is in a NAB video interview with Sony. Same limit in RX10. But some other people got conflicting information. This really needs clearing up from official sources.

Re: New Sony A7s to shoot 4K video
 

This new high-sensitivity full-frame camera opens up some interesting possibilities.Take the poor indoor sports photographer (or videographer) who has a full-frame sensor camera and needs to carry a tripod and a $11,500 Canon 400 mm f2.8 lens to be able to shoot at a decent shutter speed. If this camera gives you an additional three full stops of light, he can suddenly switch to a $1400 Canon 400 mm f5.6 lens and still have one additional stop of shutter speed. Perhaps someone will make a few very small light telephoto lenses with a maximum aperture of f 8 at a much lower price. The resolution across the lens field should be excellent at such a small aperture. Such a lens would be great for birds in flight or other outdoor photography as well, and for video you have the additional benefit of much less demanding focus. For situations when you wanted a shallow depth-of-field, a variable Gaussian blur could be added in post. I see a real future for this sensor and others like it.

Re: New Sony A7s to shoot 4K video
 

Not so long ago I had read that exmor sensor technology was restricted to small sizes. This is the first camera to utilize it for FF and the benefits are eye popping.
So far the usable iso was 4-5 stops below the highest value. If the same rule applies that means that 13200 iso could be production material which is amazing.
The only thing that remains to be seen is the dynamic range. Usually so dimly lit scenes have very high contrast, so in order to shoot with such high iso, you also need all the dynamic range you can get.
Definitely will retire a lot of flashguns...

Re: New Sony A7s to shoot 4K video
 

At the 3:17 mark of my video, the rep mentions no 30 minute limit.
If their is a 30 minute limit than perhaps that will be for most PAL territories while NTSC territories won't get a limit.

Re: New Sony A7s to shoot 4K video
 

Paulo, the lack of recording limit is good to hear!

With previous Sony SLTs and NEX cameras I didn't have as much of a problem with hitting record to stop and start the limit again as I did with the cameras overheating after 30-45 minutes in 100+ degree temps.

Re: New Sony A7s to shoot 4K video
 

Any word on price yet? I read on "the verge" that it was going to be 1,699 body only but is that site trustworthy?

Re: New Sony A7s to shoot 4K video
 

Are you talking about this article? Sony announces full-frame A7s camera that can practically shoot 4K video in the dark | The Verge

It says The A7 is $1,699 and the A7R is $2,299 so I doubt the A7S will be $1,699. It'll be closer to the A7R price if not even higher.

Re: New Sony A7s to shoot 4K video
 

When I asked the Sony guy at NAB if the $1699 price rumor was accurate he practically scoffed at me. Then he made a comment about how the only other 4k full chip camera was the Canon 1d for $10,000 and that the A7s would not be $1699.

Re: New Sony A7s to shoot 4K video
 

That Sony guy forgot to mention that for the a7s salesprice you don't get 4K but need to buy a ext recorder as well :) Looking at the prizes of the other A7 camera's now I also would doubt it will be around that prize, don't think they will try to compete with the gh4 but rather the 5dIII

Re: New Sony A7s to shoot 4K video
 

Just wanted to address some comments made earlier in this thread about resolution and frame rate.

It's not uncommon to do line skipping for higher frame rates because there is a limitation on how fast you can read out the entire sensor without frying it. The rest of the electronics have to keep up as well and it makes more sense from a design and cost standpoint to offer the higher frame rate by dropping the resolution. You can see this in a lot of cameras on the market.

Even my PDW-F350 shoulder camera did this. Anything over cranked above 30P dropped the vertical resolution from 1080 to 540. To a discerning eye, this might be visible, but the end viewer is likely to never notice.

Re: New Sony A7s to shoot 4K video
 

Did you mention the GH4? Even if it is not FF. Are they trying to pretend it has not changed the 4K price structure?

Re: New Sony A7s to shoot 4K video
 

Sony is awfully quite about their a7s price, they do have some serious competition to consider as their camera can only do 4k with another expensive investment, since 4k is the buzz word right now with many low prized serious offers pricing the a7s too high might kill their sales. Last year I saw a Dutch store giving the XLR-K1M 800 dollar xlr add on for free if you bought the vg900, that's something you don't do if sales go well so they still might be thinking where to place this a7s on their price scale compared to the competitors or they might be giving a 4k recorder with it for free if sales turn out to be bad :) Just look at what BMD did when they trashed their prices just to stay competitive, Sony could very well surprise us with a price they don't want to charge but have no other option to do so.

Re: New Sony A7s to shoot 4K video
 

I did and the guy made a comment about the GH4 not even being in the same class.

Re: New Sony A7s to shoot 4K video
 

He meant "price" class

Re: New Sony A7s to shoot 4K video
 

The way he said it sounded like the GH4 could not even be compared to the A7s. I guess because of the full chip and the supposed amazing low light performance. I do find the low light possibilities exciting but the external recorder for 4k not so much.

Re: New Sony A7s to shoot 4K video
 

The Sony Rep was correct. It can't be compared to the GH4. The GH4 can actually record a 4K image internally without expensive accessories. The Sony cannot. ;)

Re: New Sony A7s to shoot 4K video
 

How many people here believe this 12mp FF sensor was designed specifically for the A7s and the A7s "only"?...

Just what I thought....nobody!

So....how will this sensor show itself down the road again? A 4k FS200 with 4k XAVC-S onboard? Maybe at IBCI in the fall?

Hmm...I would expect to see this sensor in at least another Alpha and 1 or 2 new video cameras down the road.

Anybody care to speculate?

Re: New Sony A7s to shoot 4K video
 

Seeing as it's a 35mm full frame sensor not super35 like the FS100 and FS700, it would probably be positioned higher as say an FS900 with a price tag to match. 4K XAVC full frame low light monster.

Re: New Sony A7s to shoot 4K video
 

I think we will see it in a VG900 replacement and with a bigger body for cooling may see not only internal 4K but 60P as well ?

Ron Evans

Re: New Sony A7s to shoot 4K video
 

I figure the VG900 replacement will be identical to the A7s, but with 4k recording built into the camera since it can handle the cooling better, but otherwise will have all the same limitations (30 fps, codec, etc) as the A7s. That will let them release a FS700 replacement that has 4k, a better codec, 60 fps, etc at a much higher "pro" price. That will let their lineup of "A", "VG" and "FS" camera's co-exist at different price points, features and form factors. Although with more and more features being backed into these cameras, I have to wonder for how much longer the VG and FS lineups will both be able to co-exist.

Re: New Sony A7s to shoot 4K video
 

Differentiators would be just like my FDR-AX1 and the PXW-Z100. VG will have XAVC-S 8bit 420 and the FSxxx XAVC and XAVC-S with choices like the PXW-Z100 and hardware interfaces like SDI gen lock etc. Add to that buttons rather than menu selections and that may be all the difference. There will also be room for an EAxxx with 1" sensor of AX10 with buttons but similar codec restrictions( XAVC-S). EAxxx similar price to the FDR-AX1 giving a choice of fixed or interchangeable lens and the VGxxx a little less just like they are now. The larger camcorder bodies will support an XQD card interface needed for data rate and heat management for encoding to 60P.

Ron Evans

Re: New Sony A7s to shoot 4K video
 

Sony has so many cameras, they likely have a department dedicated just to making sure there's no in house cannibalization. I've really liked the design of the VG line, but it's been distinctly a prosumer camera, leaning towards the consumer end, and it doesn't seem likely that they'll give it anywhere near the ability that might hurt the FS line.

Then again, really all they would need to do is put in the a7s sensor, give it the same 4k codec as the ax100, and that would be enough to satisfy a lot of folks. the main problem with the vg900 being the sensor with the traditional dslr level processing and all the softness and artifacting that goes along with it

Re: New Sony A7s to shoot 4K video
 

Does anybody have any thoughts on this camera been any good for wildlife filming?
