The best source of info about future Sony cameras is: http://www.sonyalpharumors.com/

They are pretty accurate. In answer to your question, there have been no rumors of an update to the A7s. That doesn't mean there isn't one coming, but probably not in the immediate future. The next round of Sony cameras is reported to contain high megapixel sensors.

@Athiril interesting! I have no knowledge in this field, I admit, but it would possible at this point to force the dual recording of sony a7s to get 10bit in 24p?

@ AlbertZ: A7S is not delivering 10 bit.

Given that the A7s was only released 8 months ago, is still selling like hotcakes, and has no viable competition in its space, it seems unlikely that Sony would be inclined to release an update in the near future.

Have to say once again that I love my A7s. Now that I've got the Nebula Gimbal coming, I've lost interest in future Sony camera updates that would include sensor based stabilization.

I mean Nebula is going to beat sensor stabilization no matter what.

It could be 5-10 years until the local tv station changes to ultra hd so there is no pressure upgrading there either. I could see myself working with this thing for a long time.

It is truly the first small professional camera.

Stills are great too. I mean these files are much nicer to work with than bigger res files and for my work, there is absolutely nothing to be gained with more resolution.

its the same gimbal.... it can handles a7s with a small lens .

@toxotis70

The way Sony implemented HDMI is causing this. All recorders that can't handle 50p won't recognize the progressive setting in HDTV, since it looks like 50p to them. 50i will work, it's actually 25 PsF (progressive segmented frames). The Atomos ones can handle it intelligently, flagging the footage as progressive. With some others, you'll need to tell the NLE that it's actually progressive or you'll loose vertical resolution from unnecessary de-interlacing.

The Shogun will recognize 50p HDTV, but it's actually 25 fps with frame doubling. But who in the world will record HDTV if he/she has a Shogun for the A7S? BTW, true 50p looks quite crappy from the A7S, since the camera is using a feaster readout with less quality.

That's true. For this reason I'll get a Lens Turbo…

@Athril

"If you're that desperate for it, if you're shooting in 1080p, if you take 50p or 60p, and blend 2 frames together for an output of 25p or 30p within a 16-bit space you should get more than 10-bits."

If you shoot 50p then frame 1 differs from frame 2. If you blend/pixel motion blend/average frames then you end up with a new 8bit frame 3. Will fail with a lot of motion in the frame. Basicly you're creating a new picture.

Plz back up you're logic with a nuke/ae script.

@MikeLinn Such a great video!! I love the way the christmas lights look, especially when out of focus!

@jurand If you shoot those two adjacent frames with 1/100th of a second (or shorter) of exposure, the blending of two frames shouldn't look too different from footage shot at 25p with 1/50th.

That said, I'd rather shoot 4K with that extra stop in the superwhites at higher resolution, scale it down in a 32 bit application and call it a day…

very nice lighting and colors :)

@Conscius I had a GH4 and now I have a a7s. Imho, A7s it's superior in dynamic range, low light performance and cinematic look. Otherwise, GH4 it's a beast and if you own already m 4/3 lenses, your choice should be GH4.
