The X-Factor of Fudging ISO

The OMD is inflated by one stop too, so in the end there is still a one stop difference between X and OMD, in line with the sensor size difference.

Nevertheless, I predict that there will be an all out high ISO war in which camera maker start labeling their ISO 200 as ISO 6400 and declare they have the best high ISO ever, much like their world fastest AF* claim
