Pentax VS20 has a
16.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Sony HX99 has a
18.0MP (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Bionz X processor.
Below you can see the VS20 and HX99 sensor size comparison.
Sensor Size and Resolution Comparison image of Pentax VS20 and Sony HX99 Cameras
Pentax VS20 and Sony HX99 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
Pentax VS20
or the
Sony HX99 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus ),
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.
