Depth of Field on the M43 is in fact better not worse.....

All things being equal except fov, which is crucial for composition. If I'm composing a scene with my d800 and choose a 50mm lens, and needed to switch to my om-d to capture the scene, I would need my 25, not a 50 on the om-d. That's the practical side of equivalence that the mental masteurbaters like to discount. Maybe equivalence doesn't matter on paper, but it means everything in the field.

I choose to shoot my om-d for lots of different and excellent reasons, but shallow dof isn't one of them. Not that it isn't possible, its just that my d800 does it a lot better.
