Sony H55 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Bionz processor. On the other hand, Canon N has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features Digic 5 processor.
Below you can see the H55 and N sensor size comparison.
Sensor Size and Resolution Comparison image of Sony H55 and Canon N Cameras
Sony H55 and Canon N 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 N has 55% larger pixel area (3.12µm 2 vs 2.01µm 2 ) compared to Sony H55, 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
Sony H55
or the
Canon N ,
including hyperfocal distance.
