Olympus E-5 has a
12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features TruePic V+ processor. On the other hand, Fujifilm F800EXR has a
16.0MP 1/2-inch (6.4 x 4.8 mm ) sized EXRCMOS sensor and features EXR processor.
Below you can see the E-5 and F800EXR sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus E-5 and Fujifilm F800EXR Cameras
As seen above, Olympus E-5 has a 7.3x Larger sensor area than Fujifilm F800EXR. 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.
DxOMark Sensor Scores
Both Olympus E-5 and Fujifilm F800EXR sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, E-5 has scored 56, 15 points higher than F800EXR.

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-5
or the
Fujifilm F800EXR ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Four Thirds versus 1/2-inch),
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.
