Below you can see the TS2 and GXR P10 28-300mm F3.5-5.6 VC sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic TS2 and Ricoh GXR P10 28-300mm Cameras
Panasonic TS2 and Ricoh GXR P10 28-300mm 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 TS2
or the
Ricoh GXR P10 28-300mm ,
including hyperfocal distance.
