Fujifilm S1 Pro has a
3.0MP APS-C (23 x 15.5 mm ) sized CCD sensor . On the other hand, Fujifilm IS Pro has a
6.0MP APS-C (23 x 15.5 mm ) sized CCD sensor .
Below you can see the S1 Pro and IS Pro sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm S1 Pro and Fujifilm IS Pro Cameras
Fujifilm S1 Pro and Fujifilm IS Pro 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 S1 Pro has 97% larger pixel area compared to Fujifilm IS Pro, 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 S1 Pro
or the
Fujifilm IS Pro ,
including hyperfocal distance.
