steve ohlhaber: I am already doing this with synced gopros. 4k per eye 30fps. It really does look amazing on the Oculus. The gopro fisheye is 120 degrees though. In the player, the fisheye distortion is corrected as the image wraps around you. I really want a commercial camera though as my rig is a bit of a beast. I just hope it is at least as good as what I already am doing. I am not sure what they mean about 5.7k. What is that in pixels x,y axis?

5.7k should be the horizontal resolution of the stitched stereopair - not much at all, and it is not per eye. Means 2.85k per eye before cropping by the goggles from 180 degree to goggles' angle of view. If goggle has 90 degrees angle of view, the result will be 1425 horizontal pixels per eye. Really little.

Turbguy1: ...and the MOST important metric for stereo work is again not mentioned.

WHAT IS THE INTERAXIAL DISTANCE!

Seems like close to human eye base, 6.5 cm.

otto k: What stitching?

Stitching into stereopair frame to be able to use smartphone in goggles?

In fact 5.7K is not much at all, takint into account that vr goggles crop the picture from 180 degrees to e.g. 60 degrees.

I hope this is just the start. Next is a good viewer, that does not exist yet... I would even put normal good zooms instead of "180 degree vr" idea, ones that can change and accomodate angle e.g. at closeups.

brycesteiner: This looks great for single apps such as FCP and Logic.

But for screens this large and wide I would like to see a screen like this that you could split into two screens. I'm not talking about split screen built into the OS but something that the OS would really think was two screens and let a group of apps on one side and the other, just as if you would have two screens but they would be right next to each other, with an option to put a certain size column gutter in between of your choosing.
This way you could cut down on the clutter and be able to have multiple calibrations if needed (or exactly the same) but still only one physical screen!

Bryce: do you mean multiple desktops? If so - not so much in Windows, much more in Linux. But there are many ways of using multiple desktops. With my 30" screen I have also thought to make it possible co-using, but I have not found a way to simultaneously use more than one independent keyboard and independent mice - two independent mice on one screen - have anyone seen anything like that?

Bryce: I do it all the time. There are many variations of how to do that, and there is a lot of potential of further development for windows-like operating systems.

This is less then 5k resolution in the traditional meaning, i.e. compying to 16:9 standard.

In this case two mice might be needed... maybe also two groups of processors? I am all for it.

Artak Hambarian: It is a shame that 15" $3299 laptop/tablet has resolution of just 3240 x 2160, while my 4 year old 8.4" $300 Samsung Galaxy tab S is 2560x1600. With this price, to be attractive, it needs to be at least 4K or, better, 5K display.

... I would say aka 7 MP instead. And your camera has ... MP?

Are you serious? IF you have questions on resolution, the convincing answer you only can get is via next to each other low vs. high res comparison. If you can't see the difference, you don't need it.

I need simple 3d, not VR at least 4k x 2 camera and viewer. Do this step before going for much more resource demanding VR!

This is really a great camera (for a smartphone).

It is necessary to merge this device with a smartphone. I am fine with thicker device in my pocket. That will avoid the clearly weak mechanical connection of DxO. The camera internally should be more autonomous to provide fast action. This way I will carry my good camera always with me.
