Pentax P80 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Prime processor. On the other hand, Canon A1400 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the P80 and A1400 sensor size comparison.
Sensor Size and Resolution Comparison image of Pentax P80 and Canon A1400 Cameras
Pentax P80 and Canon A1400 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 Pentax P80 has 32% larger pixel area compared to Canon A1400, 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
Pentax P80
or the
Canon A1400 ,
including hyperfocal distance.
