Sony RX10 IV has a
20.0MP 1″ (13.2 x 8.8 mm ) sized Stacked BSI-CMOS sensor and features Bionz X processor. On the other hand, Panasonic FP7 has a
16.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features Venus Engine IV processor.
Below you can see the RX10 IV and FP7 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony RX10 IV and Panasonic FP7 Cameras
As seen above, Sony RX10 IV has a 4.2x Larger sensor area than Panasonic FP7. 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
Sony RX10 IV
or the
Panasonic FP7 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1″ versus 1/2.3-inch),
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.
