Near FF in 4k? You're going to need at least a 7inch monitor to nail the focus.
Rumor: Sony A7s will have 4K video

If it's bothering you, set it to f/11 and push up the ISO. Problem solved.
BTW: by the pixel count they cite, I think the EVF is 1024x576, with RGBW
mmm... at least not as good as 24p/30p

Super excited about this camera. Prepping the camera bag right now. Not much to add actually - Nikkors including Nikon 50 mm f 1.2, Heliopan ND filters, Nanoflash, IR cut filter, Nikon to e-mount adaptor, Rode videomic pro, SDXC cards, intervalometer. Now where's the order button. . . I can't stop salivating

That's what these naysayers need to listen with such high ISOs : ) It seems to me DSLRs never have been more alive than now, after all ;-) It looks like it is the video form factor to have trouble to see the light today : D Where's the AF200, above all? Did they change the name to YAGH?! So cruel these engineers are nowadays
They should be all still photographers... LOL 
That's quite common. Basically all cams do that, in 60p mode half the lines are dropped so they can be read faster.
On the Sony NEX- DSLR's it works like that (60p does look noticeably worse), and on the C100/C300, not sure about the FS700 which has a pretty fast sensor.
What?? A 7" monitor with a DSLR is a godsend and is still really, really small. I mean, the extra height is vertical so it won't be a big ass box. The BM Ursa? Ugh, looks horrible.

It's not bothering me. I was explaining that with full frame and 4k you'll be wanting to shoot with a 7inch monitor anyway. Does not matter if I'm shooting at f/11 or f/1.2, if you want 4k from this camera, as of now, you'll be using a 7inch monitor/recorder.
My point was that for ME, these cameras are best kept small for B roll shots. You can put them inside a refridgerator, or a "safe" or a nose cam or rock them in all sorts of way. For A camera for narrative work, I'm going to be using something like a Scarlet or Epic Dragon this summer, But if I had no choice but to use ope of these DSLRs as A cameras for a no budget project, then of course, I would want a 7" monitor for critical focus at the highest possible resolution!! I'm an older guy now.
Yea, I don't see the big uproar about no internal 4K. Surely anyone planning to shoot their 4K masterpiece on a GH4 will use an external box to get 10bit anyway?
7" recorder/monitor sounds about perfect for both cams.
holding off buying anything just yet though until I see some shots where banding would likely occur.

@Cory Braun:
I see: you perceive the A7s mainly as a 4K FF camera, to be used with the Shogun. I think of it as a FF camera that will give me clean and sharp 1080p with lots of DR and a strong codec. There's a sizeable chance that I'll never shoot 4K with it.
Different people, different needs... same camera!!
@macgregor:
Thinking a bit more about it, I'm also intrigued by the APS-C mode.
FF mode is 1:1 for 4K and 2:1 for 1080p, with 1.1x crop. That's an easy way to get a clean and sharp image.
APS-C is around 1.5:2 for 4K (weird) and 1.5:1 for 1080p. That's not nearly as easy to debayer, and the image will probably not be as sharp. On the plus side, it should have a lot less rolling shutter issues. But I want sharp.
If I had designed this camera, the crop mode would go to 2x, for a 1:1 1080p image. Sharp and easy, and gives you even more reach and less RS, which would be my reasons to switch to crop mode. If the sensor can output 4K at 30p, then it can output 1080p from this 2x crop at 60p.
Why this is related to your comment about line-skipping above 30p: if the APS-C image is sharp, maybe that's what you want to use for higher fps, because line-skipping can start at a higher fps (or maybe not; we'll see).
Ah, details, details...
And a very important one is still missing: PRICE!!

Nope, that's not my perception at all. Was just referring to the people complaining about needing a 7 inch monitor to record 4k. My point was that if you want to record 4k, having a 7inch monitor is not a bad thing. That's all.

The vimeo clip was enough for me to part with $2000+ just to test the A7s for my feature shooting in 1080p. 4k is a wank. Look at all the great stuff shot on the Alexa. If you're all about the pixels you don't need a camera you need a therapist. Seriously look at the COMPRESSED vimeo clip again and tell me you need more pixels. At 1080p this beast looks like film and that's what counts. In 6 years this is the first DSLR that truly looks feature film worthy out of the box.

I couldn't imagine shooting Slog without an external monitor with waveform etc. Does the A7s have any built in exposure tools for the 1080p recording internally?
The cherry blossoms video didn't seem all that special to me especially considering the brought in someone to make the video for launch. I'll wait and see what comes out when user footage starts to leak out.

Histogram and zebras for exposure, peaking and 8x zoom for focus. I think that's it.
(Sony's peaking is really good, and I think I've read somewhere that zoom-in can be used while recording)
(I already bought a light meter for use with the BlackMagics, the A7s can't possibly be any worse than those in this respect)
I think Cherry Blossom was shot with strict direction from Sony: "we want a clip that sells TVs, not cameras; we want stationary shots that look really, really sharp; we're going to loop this on our 4K TVs over and over"

I didn't know there was other footage. I'll take a look at the Scotland stuff. I assume its on the A7s official Sony page?
