These results should be viewed as disappointing. In low light, the original A7S outperforms the A7S II!
I totally agree. Its a massive disappointment, as the A7R II got a massive upgrade in every area of operation / performance, the only real hardware upgrade the A7S II received was IBIS.
What about internal 4K recording you say? SLog3? Well, that and other more minor improvements were merely firmware updates that could have been sent out to the A7S as well, by a more customer friendly company.
- it kept the old sensor with no improvement to processing speed, which would have been useful for video in various ways, including reduction of rolling shutter induced issues when panning.
- it lost sensitivity
- its insufficient color space produces banding
- the AF still sucks, The AF improvements of the A7R would not only be welcome, but EXPECTED, given that it costs very close to the same.
I know I'm forgetting some things.
So, Sony seriously cheaped out on the A7S II update in a blatant cash-grab.
The A7R is a far better value proposition - Videographers are forced to pony up the same money for a lot less.
Sure, you can say it'll still do video fairly well within the limits of the old sensor, but really - other than the A7S II's sensor resolution being better for video, the A7R II is better at photography and video in every other area, especially AF and processing speed.
With a low resolution version of the A7R II's sensor technology, the A7S II would be able to do 120 fps in 4K
