Panasonic BS1H has a
24.2MP Full frame (35.6 x 23.8mm ) sized CMOS sensor . On the other hand, Sony FX6 has a
10.9MP Full frame (36 x 24 mm ) sized CMOS sensor .
Panasonic BS1H's sensor provides 13.3MP more than Sony FX6'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 BS1H and FX6 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic BS1H and Sony FX6 Cameras
Panasonic BS1H and Sony FX6 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 BS1H
or the
Sony FX6 ,
including hyperfocal distance.
