Sensor Size and Resolution Comparison image of Fujifilm Real 3D W1 and Nikon S3100 Cameras
Fujifilm Real 3D W1 and Nikon S3100 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.
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 Real 3D W1
or the
Nikon S3100 ,
including hyperfocal distance.
