Atmos Shogun which is due this fall I believe.

I think the Mitch (07q) said something like 'there is a route in the pipeline' -

Yes, we will have a solution.

Either way it's still going to be a compromise until someone figures out how to hack it for the raw data. I'm going for a kinda late 70s lo-fi grainy look anyway so a bit of colour bleed and softness is ok, and I should be able to mask any banding. Macroblocking is a lot harder to deal with and just screams digital.
The pix 220 just arrived. The fan is very quiet but I think the mic might still pick it up in a quiet scene in a confined space so I might have to get a Shogun or Odyssey anyway or just stick with the internal codec where necessary if it's good enough.
Mitch if you include a Prores 4444 2k & 4k option that would somewhat offset the sound shortcomings.

When Mitch? and when on the GH4?

When I can say that for sure, I will. Otherwise, all I can state is "soon".
There's nothing discrete about the recorder add on, but yes the stand alone a7s looks like it will be a big step up from other DSLR's in terms of quality and size
never played with the a7 or the a7r, so curious to see how it feels in the hand

I don't imagine 4K recorders will be getting too much smaller than the 7Q very soon. Why not just take any of the ones you think aren't discreet and put them in a discreet bag/backpack and run tethered? Or if you really need the most discreet, the best option will likely be 1080p internal recording...

As far as I know, not at the moment. However, together with the 4K Shogun, Atomos had also announced a compact hdmi recorder, the Ninja Star
http://www.redsharknews.com/technol...-ninja-star,-its-smallest-prores-recorder-yet
while it currently only records 1080p, maybe if there is enough demand from owners of Sony A7S, GH4 and any other future 4k cameras, I'm sure they'd consider offering a 4K version. Having said that, Atomos might be afraid it would cannibalize the sales of their own 4K Shogun recorder, which will certainly be the go to option for Sony A7S users. On the other hand, a sub $500 compact 4K recorder would lower the total cost for 4k acquisition and offer a less bulky, more stealthy and manageable option then the A7S plus Shogun, boosting sales of Sony's camera and consequently sales for Atomos.
Additionally, the Sony AX100 also seems to have an uncompressed 4k HDMI output, according to the ever knowledgeable Andrew Reid of EOSHD, (http://www.eoshd.com/content/12659/brief-look-sony-ax100-4k-handy-cam), such a compact and cheap recorder might also appeal to anyone put off by this camcorder's low video bitrate (60Mbs XAVC-S for 4k). With the Sony AX100 being compared favourably to the GH4 for quality, I for one would be tempted by a 4k handycam which could also record uncompressed footage for about $2.5k
P.S. Here's a very informative discussion about the Ninja Star (compact HDMI recorder mentioned above) on Personal View. Again, to be clear, if the design can be upgraded to 4K is mere speculation at this point, as currently this recorder can only manage 1080p. Maybe someone from Atomos can chime in and contribute to this thread? http://www.personal-view.com/talks/discussion/10110/cfast-storage/p1 and http://www.personal-view.com/talks/discussion/comment/169361#Comment_169361

I wouldn't be too happy about a recorder that doesn't show me what it is actually recording. Kind of like recording audio without headphones: if there's a bad connection somewhere, you'll only find out back at home. A Ninja 3 with 4K recording, that's what I'll be waiting for.

It does have a ton of LEDs for everything including HDMI connectivity. If there is a bad connection, it will let you know! Again, this is all speculation at this point, as the Ninja Star is currently a 1080p recorder. However, I've read several posts asking for a similar small 4k recorder, so fingers crossed, Atomos or BlackMagic will eventually release one. On a different note, EOSHD have just published a low light test, and it knocked my socks off! Makes me wish I could afford this little wonder!

Before the 7q future path is announced, I was hoping the 7q would record the a7s in 1080p 50/60 already, but it looks like it has issues.
does anyone have the a7s and a 7q who can test?
This issue with the 7q still not being able to take a 50/60p signal from a hdmi camera via an sdi converter persists in the new firmware and has in fact got worse. You can still take a 1080i signal and get Psf or now i up to 30p, that's it.
i really would have thought catering to sony a7s users for more sales would have been a tested priority. As it stands looks like the 7q cannot take a progressive converted hdmi input on sdi, and still maxes out at 30p for converted hdmi > sdi signals.
Anyone got one yet and latest 7q firmware who can confirm the a7s output is fixed to 50/60p/50/60i for full sensor readout?

I just got my A7s and I have the O7Q, so I will be starting extensive testing this week.
I plan on using the O7Q and the Shogun, there will be a path to get 4K recorded by the O7Q though I will not venture to guess how soon. But I think CD is very anxious to compete with Atmos so it may be sooner than you think. I also have a Black Magic recorder I will try out.
Of course I will be testing both the NanoFlash and Odyssey as a 1080 recorder first, I have the Shogun on order as well. I see the A7s as Bcam to the FS700 and then I need 2 recorders anyway. Though I keep hearing rumors of a much smaller 4K recorder from CD, I would love that and if it happens quickly maybe that will be the route to take.
Anyway I will be posting my test results here. As this is an 8Bit cam I have a feeling I will not be using S-log much except for very contrasty scenes. So I plan to spend time in my suite with scopes building PPs for most typical scenes, just like I have for every new cam.
Stay tuned for more...

Awesome!! Looking forward to your findings!!
Somebody posted a link to this video in the sample footage thread but nobody responded.
I think it's probably more relevant to this discussion anyway.
It's a moire test comparing GH4 internal 4k and the 4k output of the A7s. The A7s exhibits moire which is surprising.
http://www.youtube.com/watch?v=75DAsjWVTjw
The uploader has also posted a video describing how he is recording the 4k, which is fairly elaborate.
https://www.youtube.com/watch?v=Tj2NWpkAXqk
Could the method of recording be introducing the moire in the test?

This probably has more to do with the fact that 4K optical resolution on FF sensors is much more easily exceeded by lenses than 4K optical resolution on mft sensors. Differences in OLPF cut-off frequencies will also affect the results.
It doesn't look to me that the 1080p A7S video has less moire than 4K, it just uses a smoother (and better) downscale algorithm (than the gh4), which in turn leads to the perception of less moire in 1080p.
