Hi everyone. I have the K-3 III for three weeks now, and it is a great improvement as tool over my old K-5 (I don't really see a difference in image quality at ISO 400 or less).

But with the K-3 III, I saw that I'm mainly shooting with ISO 200 (with auto range 100-6400), when the K-5 was using mainly ISO 100.

I didn't read anything about the default ISO setting of the K-3 III sensor. Could it be ISO 200? On K-5, default was 100, but it could be extended to ISO 80.

I tried every advanced ISO configuration, but even at with plenty of light, it is most of the time stuck at 200. Maybe it is related to the Av mode, but I don't know, as I don't use often other modes.

I just don't understand how the auto ISO works on the K-3 III. Sometimes it is blocked on ISO 200 at 1/4000 s, and other times it uses ISO 100 at "slow" speed of 1/250 s.

Thanks, that's was it. I let it as default on auto for the K-3 III, but I had disabled on the K-5.
Without it, I have now correctly ISO 100 as default.

I should test what this dynamic range correction is doing, but I don't understand how the gain (ISO) is related to the 14 bit to 8 bit conversion for JPEG. It may be relevant when shooting RAW, but then is it useless for JPEG?

It is for JPGs.

Your RAW image will be one stop underexposed.
