Sony HX90V has a
18.0MP (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Bionz X processor. On the other hand, Casio EX-ZR800 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features EXILIM Engine HS 3 processor.
Below you can see the HX90V and EX-ZR800 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony HX90V and Casio EX-ZR800 Cameras
Sony HX90V and Casio EX-ZR800 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.
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 HX90V
or the
Casio EX-ZR800 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
( 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.
