Fujifilm J30 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Fujifilm XP200 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor .
Below you can see the J30 and XP200 sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm J30 and Fujifilm XP200 Cameras
Fujifilm J30 and Fujifilm XP200 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 J30 has 32% larger pixel area compared to Fujifilm XP200, 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 J30
or the
Fujifilm XP200 ,
including hyperfocal distance.
