Meanwhile not only Sony fans are eagerly waiting for a successor to the Sony Alpha 7 S II. While Panasonic, Nikon and Canon are already placing very interesting full format DSLMs for filmmakers on the market, they also want to know what Sony&s upcoming "A7 for filmmakers" will have to offer. Rumor has it that the new A7s will finally exceed the expectations of the waiting users.
Now the user "androidlad" has published a specification table in the EOSHD forum, and after he was right with his leaks several times, there could be something to it here.
The A7s is supposed to come on the market with version number IV - which seems plausible, since the S-model in generation III hasn&t got an update and version II has been on the market for an unusual long time. We believe that a new DSP with new codecs is "to blame" for the delay, which has not been available yet. At least 10 bit 4:2:2 (probably in HEVC) should be implemented to avoid falling behind the competition. At the same time you have of course your own FX9 in mind, which should not be cannibalized. But a 30 minutes recording limit could be enough for that. More details about the codecs are unfortunately not yet available.
Otherwise, the now rumored specification details don&t make you sit up and take notice: stabilized 15 MP sensor with 7.52 µm sensor size, dual UHS-II slot, full sensor readout in 4.8K (4752 x 2684) with 24-30p, 4K in 48-60p only in the S35 window crop. Additionally FullHD slow motion up to 120 fps.
Exactly what you expect from a Sony a7SII successor. Interesting is however a small reference with the "Pixel Size". So here beside the 7.52µm in brackets is the note "3.76µm, 2x2 OCL".
And this is interesting again, because Sony has presented the 2x2 On-Chip Lens (OCL) technology officially only one month ago. This technology promises improved autofocus characteristics (especially in low light), but in return reduces the light sensitivity in FullWell by about one f-stop compared to a real 7.5 µm sensor.
We are already very curious if and how all this will materialize in a new A7S VI. And of course when...
