Canon A4000 IS has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Olympus TG-310 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features TruePic III+ processor.
Below you can see the A4000 IS and TG-310 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon A4000 IS and Olympus TG-310 Cameras
Canon A4000 IS and Olympus TG-310 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 Olympus TG-310 has 15% larger pixel area (2.04µm 2 vs 1.76µm 2 ) compared to Canon A4000 IS, 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
Canon A4000 IS
or the
Olympus TG-310 ,
including hyperfocal distance.
