Z CAM E2 4K has a
10.3MP Four Thirds (19 x 13 mm ) sized CMOS sensor . On the other hand, Panasonic GH7 has a
25.0MP Four Thirds (17.3 x 13 mm ) sized BSI CMOS sensor .
Panasonic GH7's sensor provides 14.7MP more than Z CAM E2 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.
One other difference between these two cameras that is worth mentioning is that Panasonic GH7's sensor doesn't have an anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the E2 and GH7 sensor size comparison.
Sensor Size and Resolution Comparison image of Z CAM E2 4K and Panasonic GH7 Cameras
Z CAM E2 4K and Panasonic GH7 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
Z CAM E2 4K
or the
Panasonic GH7 ,
including hyperfocal distance.
