This graph is about right.

So after psoting this graph about 10 times you finally agree. As you can see the difference for almost every ISO is about 1/2 stop. Nowhere is it the 3 stops you claimed.

It is 14.2 over 12.7 at base ISO, but you are looking at the shadows only. Look at how they compare in the headroom. From dark to white you get almost 3 stops difference. Well, fraction less, but you can safely round it up to the nearest digit. Also look at the color depth, hmm, I think you are upset enough for today already.

For the record, when you kept saying I was posting the non-nomalized graph, here that is which shows the E-M1 is virtually the same. For practical purposes we should not use it and the one above is more useful. Notice there is NOT a 1.5 stop difference between graphs.

Whatever. We get the picture
