Canon EOS C70 has a
8.9MP Super 35 (26.2 x 13.8 mm ) sized CMOS sensor . On the other hand, Panasonic BS1H has a
24.2MP Full frame (35.6 x 23.8mm ) sized CMOS sensor .
Panasonic BS1H's sensor provides 15.3MP more than Canon EOS C70'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 C70 and BS1H sensor size comparison.
Sensor Size and Resolution Comparison image of Canon EOS C70 and Panasonic BS1H Cameras
As seen above, Panasonic BS1H has a 2.3x Larger sensor area than Canon EOS C70. 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
Canon EOS C70
or the
Panasonic BS1H ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Super 35 versus Full frame),
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.
