This is very interesting.

I compare this to results from a similar test on a NEX 5N. The 5N shows a change from ISO 100 to 200, then no change (like the Merrill) from 200 to 1600, then above 1600 increasing ISO by one stop moves the data up by one stop.

My test subject is a grey card on which are placed a piece of black velvet and a piece of white paper. This gives three clear peaks which are easier to see on the histograms.

Raw Digger is a very useful program.

But if camera companies provided proper technical manuals for the equipment they sell, this laborious digging would not be needed.
