Z CAM E2C 4K has a
16.8MP Four Thirds (17.56 x 13.11 mm ) sized CMOS sensor . On the other hand, Blackmagic 6K G2 has a
21.0MP Super 35 (23.1 x 13 mm ) sized CMOS sensor .
Blackmagic 6K G2's sensor provides 4.2MP more than Z CAM E2C 4K'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 E2C and Cinema Camera 6K G2 sensor size comparison.
Sensor Size and Resolution Comparison image of Z CAM E2C 4K and Blackmagic 6K G2 Cameras
As seen above, Blackmagic 6K G2 has a 1.3x Larger sensor area than Z CAM E2C 4K. 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
Z CAM E2C 4K
or the
Blackmagic 6K G2 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Four Thirds 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.
