Olympus PEN-F has a
20.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features TruePic VII processor. On the other hand, Panasonic GH4 has a
16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine IX processor.
Below you can see the PEN-F and GH4 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus PEN-F and Panasonic GH4 Cameras
Olympus PEN-F and Panasonic GH4 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Olympus PEN-F
or the
Panasonic GH4 ,
including hyperfocal distance.
