Olympus E-PL1 has a
12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Truepic V processor. On the other hand, Panasonic GF6 has a
16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine FHD processor.
Below you can see the E-PL1 and GF6 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus E-PL1 and Panasonic GF6 Cameras
Olympus E-PL1 and Panasonic GF6 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-PL1 has 29% larger pixel area compared to Panasonic GF6, 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-PL1
or the
Panasonic GF6 ,
including hyperfocal distance.
