Henry showing the difference between sensors

Lol, instead of 2x I will use 1.5x for A7 and 1.8x for A7r. So, at equivalency, the M1 will be slightly better?

Sorry but apparently you still didn't get it. As you can see from the diagram above, the E-M1 is about 1.5 EV ahead for equivalent images and about 0.5 EV behind for non-equivalent ones (same exposure, different DoF).

It is about 1.5 stops behind when you take pixel count into consideration, and is another 1.5 stop behind in headroom (highlights). So we are talking 3 stops difference from dark to white. Clearly the images from Sony will look smoother and more pleasing than the images from the OMD.
