Canon A3100 IS has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, RED Komodo-X 6K Z has a
19.9MP Super 35 (27.03 x 14.26 mm ) sized CMOS sensor .
RED Komodo-X 6K Z's sensor provides 7.9MP more than Canon A3100 IS'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 A3100 IS and Komodo-X 6K Z sensor size comparison.
Sensor Size and Resolution Comparison image of Canon A3100 IS and RED Komodo-X 6K Z Cameras
As seen above, RED Komodo-X 6K Z has a 13.7x Larger sensor area than Canon A3100 IS. 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
Canon A3100 IS
or the
RED Komodo-X 6K Z ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus Super 35),
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.
