All things being equal, the DOF on MFT and APSC difference if any is almost negligible in the end results

The more important factors here are quality of bokeh and availability of fast lenses which can yield those 2 desired factors


Just in order to still make a comparison, assume a worse case scenario, i.e. standard kit lenses with slow and short tele:

  • Sony NEX (APSC) + Sony E 18-55mm F3.5-5.6 OSS

  • Olympus MFT + Olympus M.Zuiko Digital 14-42mm 1:3.5-5.6 II

and a field of view that is equivalent to a portrait of the upper body, i.e. height of the portrait approx. 0.6m, distance 1.4m, zoom approx 84mm equivalent, aperture 5.6 for both.

Store those 2 pictures from the article, they will give you the respective background blur for the two cameras above (... ah ... apologies, you said no flower shots ... ):

Afer storing them flip between them. You will notice a slight increase in the blur spots in the back between the two. The one with the bigger blur spots would be APSC the other MTF. Every other lens with either a longer zoom or faster aperture will do better ... and as said above quality of the bokeh is whole different matter on its own.
