Olympus 8000 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Z CAM E2-M4 II 4K has a
10.3MP Four Thirds (19 x 13 mm ) sized CMOS sensor .
Below you can see the 8000 and E2-M4 Mark II sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus 8000 and Z CAM E2-M4 II 4K Cameras
As seen above, Z CAM E2-M4 II 4K has a 8.9x Larger sensor area than Olympus 8000. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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 8000
or the
Z CAM E2-M4 II 4K ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus Four Thirds),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
