* Flange back distance half that of Four Thirds (20 versus 40 mm)
* Lens mount diameter 6 mm smaller (44 versus 50 mm)
* Contrast Detect AF is implied (passive would require an external sensor)
* Lens to body electrical contact points up to 11 from 9
* Lenses of same focal length and maximum aperture considerably smaller than Four Thirds
* Enables slim and compact lens-interchangeable digital cameras
