I never paid much attention to the DRO settings. It was usually "OFF". Recently, I was looking at it.
On the NEX' the DRO settings (LV1 to LV5) appear to have very subtle effects. However, on FF (A7/7r/7s), the difference appears to be quite noticeable.
I have a question: Is the DRO (curves) baked into the RAW files or is it just for JPEGS?
