FujiFilm JZ500 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Fujifilm JZ200 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the JZ500 and JZ200 sensor size comparison.
Sensor Size and Resolution Comparison image of FujiFilm JZ500 and Fujifilm JZ200 Cameras
FujiFilm JZ500 and Fujifilm JZ200 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 FujiFilm JZ500 has 6% larger pixel area compared to Fujifilm JZ200, 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
FujiFilm JZ500
or the
Fujifilm JZ200 ,
including hyperfocal distance.
