Both Olympus E-PL8 and Kodak S-1 have Four Thirds sized 16.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the E-PL8 and S-1 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus E-PL8 and Kodak S-1 Cameras
Olympus E-PL8 and Kodak S-1 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. On the other hand, since Olympus E-PL8 has 1% larger pixel area compared to Kodak S-1, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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 E-PL8
or the
Kodak S-1 ,
including hyperfocal distance.
