Panasonic AW-UB50 has a
24.2MP Full frame (35.6 x 23.8mm ) sized CMOS sensor . On the other hand, Canon EOS C400 has a
19.0MP Full frame (36 x 24 mm ) sized BSI Stacked CMOS sensor .
Panasonic AW-UB50's sensor provides 5.2MP more than Canon EOS C400'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 AW-UB50 and C400 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic AW-UB50 and Canon EOS C400 Cameras
Panasonic AW-UB50 and Canon EOS C400 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the 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
Panasonic AW-UB50
or the
Canon EOS C400 ,
including hyperfocal distance.
