Sony will be unveiling the long-awaited Alpha a7s III tomorrow. For now, it appears a lot of the specifications and now images have leaked ahead of tomorrow's announcement.
Sony Alpha a7s III specifications: (Via SAR)

- Only up to 4k60 will be 10bit 4:2:2 internal.
- Downsampled 1080p from 4K, making this the best 1080p hybrid ever made! No line skipping or pixel binning.
- No internal RAW.

- Movie Edit add-on compatibility for Image Stabilization in post
- World’s highest resolution new 9.44 million dot EVF (QXGA resolution)
- Same Sony A7rIV AF system
- New kind of passive (noise-free) cooling system
- UHS-II card and CFexpress Type A card support (each of the two slots takes them both!)

also, a bit more pixels and that EVF would have been the same resolution as the sensor...strange choices, sony.. :)))
we should wait dpreview to adding R5 ,R6 & A7SIII into video still comparison tool
Never thought that we will have this fast more then the high end 5,7MP currently!
Also the dual sd/cfe cardslot is awesome!! The R5 should have this too!
But I think this camera is a bit late.... no RAW internal... and really expensive for a 12MP small video camera with FE mount?
Maybe they could give it a new name like A7v (v for video)?!^^
Astrophotographer will not switch I think.
There must be a reason for 12MP.
I am still confused though, what does this practically mean? " Records FHD 240fps, 4k120fps 10bit 4:2:2 and 4K120fps raw over HDMI " and only up to 4k60 will be 10bit 4:2:2 internal . Are there external recorders who can do those? For how much?
Aren’t reported EVF dot counts ”marketing values” ie. total number of RGB subpixels rather than what we usually mean by pixels? (Hence ”dots” instead of ”pixels”.) So assuming there are three dots per pixel (could be four as well) the math would work out toabout half the linear resolution of the sensor.
But $4000? Will it actually shoot stills btw??
But, in all honesty, if the camera can shoot in all 4K modes all day, this is a winner. Canon swung for the fences and hit the foul poles. The R5 and R6 sacrificed reliability over winning the spec war and it may come back to haunt them. If these are the specs of the A7SIII, then I feel sorry for Sony shooters that were waiting for this camera for so long. It's internal recording capabilities don't feel that impressive, but if they work reliably, that might be all that matters to people who really use their gear professionally. It appears everyone just wants to stick with 4K. 8K is neat, but impractical for average use.
Not quite, the EVF is 9.44 M-Dots but only 3.14MP. Still, really exciting to see such a high resolution EVF. Hopefully the viewfinder magnification has been scaled up to take advantage of all that resolution.
