Olympus TG-870 has a
16.0MP (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features TruePic VII processor. On the other hand, Panasonic TS4 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features Venus Engine FHD processor.
Below you can see the TG-870 and TS4 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus TG-870 and Panasonic TS4 Cameras
Olympus TG-870 and Panasonic TS4 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
Olympus TG-870
or the
Panasonic TS4 ,
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.
