Panasonic S1H has a
24.0MP Full frame (35.6 x 23.8 mm ) sized CMOS sensor and features Venus Engine processor. On the other hand, Sony FX3 has a
12.0MP Full frame (35.6 x 23.8 mm ) sized BSI-CMOS sensor and features Bionz XR processor.
Panasonic S1H's sensor provides 12MP more than Sony FX3'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 S1H and FX3 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic S1H and Sony FX3 Cameras
Panasonic S1H and Sony FX3 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Sony FX3 has 99% larger pixel area (70.55µm 2 vs 35.30µm 2 ) compared to Panasonic S1H, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
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 S1H
or the
Sony FX3 ,
including hyperfocal distance.
