Canon A1200 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features DIGIC 4 with iSAPS technology processor. On the other hand, Nikon L830 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor .
Below you can see the A1200 and L830 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon A1200 and Nikon L830 Cameras
Canon A1200 and Nikon L830 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 A1200 has 32% larger pixel area compared to Nikon L830, 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 A1200
or the
Nikon L830 ,
including hyperfocal distance.
