FujiFilm F70EXR has a
10.0MP 1/2-inch (6.4 x 4.8 mm ) sized CCD sensor and features EXR processor. On the other hand, Olympus E-M10 III has a
16.0MP Four Thirds (17.4 x 13 mm ) sized CMOS sensor and features TruePic VIII processor.
Olympus E-M10 III's sensor provides 6MP more than FujiFilm F70EXR's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the F70EXR and E-M10 III sensor size comparison.
Sensor Size and Resolution Comparison image of FujiFilm F70EXR and Olympus E-M10 III Cameras
As seen above, Olympus E-M10 III has a 7.4x Larger sensor area than FujiFilm F70EXR. 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
FujiFilm F70EXR
or the
Olympus E-M10 III ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2-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.
