I have been waiting for the price of the Sony A7S to go down and suddenly there is the A7II to consider. Which one is the better camera from manual glass (especially wide glass) and which is the better camera for low light photography? The A7II still has the same sensor as the A7, right?

no sure answers yet..
but I suppose that the 7S does a bit better with RF wide angles and high ISO, the IBIS of the A7II often will save on ISO though.
better high ISO of the A7s as compared to A7II shown here at abt. minute 10:40: https://www.youtube.com/watch?v=VEEtD1AUtbw

yes, A7 and A7II have the same sensor ( AF on II is improved though )

Thanks for your input. But there's a contradiction right there (one that I have been curious about). Either it is the same sensor or it is not. You (and others) say that it is improved.

I am not a technical guy, but from how much I understand A7 and A7II have same sensor, that is also have the same number of AF points, the AF algorithms of the A7II however are new, taken from Alpha 6000 ( is this possible or contradicting? )

I'm not a technical guy either. But I guess that the processing and the AF algorithms could be improved. Maybe those will come to the A7 as a future Firmware upgrade. But it sounds to me as if the sensor itself is the same hardware as the one in the A7.

The main thing that to me, the A7S is a full frame sensor, while the A77II is an APS-C 'crop' sensor. I know I want a full frame digital camera in the near future. The A7 line and the A77 have different sensors.

Phil some confusion there. We are not comparing A7s to A77 but to A7 Mark II or A7II, which also is a FF camera, the newest of the Sony mirrorless FF cameras, just released, that sports 5 axix in body stabilization ( IBIS ) http://www.luminous-landscape.com/reviews/cameras/sony_a7_mkii_hands_on.shtml

Your right, I did not read carefully.

The A7S is better for most normal and wide angle lenses, where the lack of stabilization might not be a big problem.
Only issue is the ergonomics not being as good as the A7II.

And it may not need the fast glass as much as other cameras, so some cost could be re-gained there, especially with rangefinder lenses, where the price gap is much wider.

DXOmark of the A7II is out, interestingly it scores quite a bit better for high ISO than the A7, but falls a bit behind in DR:

( A7s is included in the comparison, best high ISO but lowest DR and color depth scores )

I am starting to lean towards the A7II.

High ISO capabilities offer fast shutter speeds, a stabilizer enables you to hold steady at a slower shutter speed - which doesn't help when freering moving subjects.

I usually prefer a better ISO performance to an IS. Others prefer the IS.

Is the default shutter speed still 1/60th on the mark 2 ?
