Sony HX9V has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features BIONZ processor. On the other hand, Panasonic FZ150 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor .
Below you can see the HX9V and FZ150 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony HX9V and Panasonic FZ150 Cameras
Sony HX9V and Panasonic FZ150 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 Panasonic FZ150 has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Sony HX9V, 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
Sony HX9V
or the
Panasonic FZ150 ,
including hyperfocal distance.
