20.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Venus Engine processor. On the other hand, Samsung ST93 has a
16.0MP 1/2.3-inch (6.16 x 4.62 mm ) sized CCD sensor .
Below you can see the ZS80 and ST93 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic ZS80 and Samsung ST93 Cameras
Panasonic ZS80 and Samsung ST93 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
Panasonic ZS80
or the
Samsung ST93 ,
including hyperfocal distance.
