Panasonic TS20 has a
16.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Panasonic TS3 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 TS20 and TS3 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic TS20 and Panasonic TS3 Cameras
Panasonic TS20 and Panasonic TS3 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 TS3 has 32% larger pixel area (2.31µm 2 vs 1.74µm 2 ) compared to Panasonic TS20, it has larger pixel area to collect light hence potential to 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 TS20
or the
Panasonic TS3 ,
including hyperfocal distance.
