Panasonic ZS50 has a
12.0MP (6.17 x 4.55 mm ) sized CMOS sensor . On the other hand, Olympus TG-4 has a
16.0MP (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features TruePic VII processor.
Below you can see the ZS50 and TG-4 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic ZS50 and Olympus TG-4 Cameras
Panasonic ZS50 and Olympus TG-4 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. On the other hand, since Panasonic ZS50 has 32% larger pixel area compared to Olympus TG-4, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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 ZS50
or the
Olympus TG-4 ,
including hyperfocal distance.
