If cameras are ISO-invariant these days...

Many models these days are visibly ISO-invariant, meaning that you can take a picture at 1/800 sec ISO 800 or take the same picture at 1/800 sec ISO 100 and push 3 stops at post processing, getting the same noise levels and the same picture.

My question: when are we going to see the first camera that doesn't do amplification to the picture at all -- every picture gets recorded at the optimal base ISO.

The picture would be digitally amplified in-camera to match the user-set ISO for review/preview/JPEG/AWB purposes but the raw file in essence would be at base ISO with a premade exposure comp applied to it so that users don't have to always start from blackness.

This would mean hella less blown skies and other things

Software-based cameras could do it. It's just a matter of optimizing the processing and reducing down the amount of time to capture the photo so shot-to-shot time is responsive and transparent to the user.

With the recent development of a sensor that doesn't overload, instead counting the number of times the light value fills the pixel to maximum, we're very close to an ISO-invariant camera.
