Nikon S3300 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Fujifilm XP30 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the S3300 and XP30 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon S3300 and Fujifilm XP30 Cameras
Nikon S3300 and Fujifilm XP30 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 XP30 has 14% larger pixel area (2.01µm 2 vs 1.76µm 2 ) compared to Nikon S3300, 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
Nikon S3300
or the
Fujifilm XP30 ,
including hyperfocal distance.
