Canon SD3500 IS has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Digic 4 processor. On the other hand, Canon A3300 IS has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features DIGIC 4 with iSAPS technology processor.
Below you can see the SD3500 IS and A3300 IS sensor size comparison.
Sensor Size and Resolution Comparison image of Canon SD3500 IS and Canon A3300 IS Cameras
Canon SD3500 IS and Canon A3300 IS 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 SD3500 IS has 14% larger pixel area compared to Canon A3300 IS, 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
Canon SD3500 IS
or the
Canon A3300 IS ,
including hyperfocal distance.
