Sony confirmed it will have a live press conference at 9.30am CET on Friday 14. Trusted sources told us Sony will announce a new PRO camcorder. They have no info yet about a possible E-mount announcement. We still don’t know if the Sony A7sIII will be announced on September 14 or if Sony will wait out the Canon-Nikon-Panasonic FF camera launch storm first.
The only reliable info I got about the Sony A7sIII so far is this:
Source 1 (with a track of sharing 5 correct rumors out of 6)
4K HDR 60P
The sensor is Exmor RS
The number of pixels is unknown.
Sony is nervous about information leakage, it is difficult to obtain detailed specifications.
But according to sources, the A7S III is amazing, it is really amazing.
Source 2 (with a track of sharing 4 correct rumors out of 4)
The sensor of a7sIII would be new stacked CMOS sensor with integral memory
which means a7sIII would have 4KHDR/60P.
The sensor is technically superior to a9/fs sensor.
