Panasonic SZ7 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CMOS sensor . On the other hand, Panasonic LZ30 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the SZ7 and LZ30 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic SZ7 and Panasonic LZ30 Cameras
Panasonic SZ7 and Panasonic LZ30 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
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 SZ7
or the
Panasonic LZ30 ,
including hyperfocal distance.
