I just purchased a Sony Alpha 7s. Can anyone tell me what the native ISO is on this camera, and also what the best picture profile to use is as well as S Log?

> native iso
100. What else?

But you could set the Auto ISO limit to 25600 or something.

native iso is the tension the sensor was designed to operate with. higher iso raises the tension lower lowers it. in brief. a cam can be native 200 but offer iso 160.

Native ISO is ISO 100.

Of course Sony will direct you to the native ISO of their s-log profiles, too (lowest settings).

Wow, a flat line from ISO100 on up, this camera is totally ISO invariant. You can shoot at ISO 100 and push in post as much as you want and it'll be the same thing.

The ISO invariance has been described as not being complete:

"Sony A7S (I was interested to see this one. The noise pattern on the brightened image is close to the high ISO shot. However, the brightened image lost a SURPRISING amount of contrast)."

No. How are you even reading the measurements?!

Fuck no? The camera's "x vs increasing ISO" curves are indeed very nice, but they are curves.
