Nikon P600 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Sony W550 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features BIONZ processor.
Below you can see the P600 and W550 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon P600 and Sony W550 Cameras
Nikon P600 and Sony W550 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 Sony W550 has 14% larger pixel area (2.01µm 2 vs 1.76µm 2 ) compared to Nikon P600, 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
Nikon P600
or the
Sony W550 ,
including hyperfocal distance.
