Panasonic FZ200 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features Venus Engine VII FHD processor. On the other hand, Olympus SP-100 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor .
Below you can see the FZ200 and SP-100 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FZ200 and Olympus SP-100 Cameras
Panasonic FZ200 and Olympus SP-100 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 FZ200 has 32% larger pixel area compared to Olympus SP-100, 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
Panasonic FZ200
or the
Olympus SP-100 ,
including hyperfocal distance.
