Canon ELPH 340 HS has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features DIGIC 4+ processor. On the other hand, Canon ELPH 300 HS has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features DIGIC 4 with iSAPS technology processor.
Below you can see the ELPH 340 HS and ELPH 300 HS sensor size comparison.
Sensor Size and Resolution Comparison image of Canon ELPH 340 HS and Canon ELPH 300 HS Cameras
Canon ELPH 340 HS and Canon ELPH 300 HS 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 Canon ELPH 300 HS has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Canon ELPH 340 HS, 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 ELPH 340 HS
or the
Canon ELPH 300 HS ,
including hyperfocal distance.
