Panasonic LZ30 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Sony W510 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features BIONZ processor.
Below you can see the LZ30 and W510 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic LZ30 and Sony W510 Cameras
Panasonic LZ30 and Sony W510 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 W510 has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Panasonic LZ30, 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
Panasonic LZ30
or the
Sony W510 ,
including hyperfocal distance.
