Sensor Size and Resolution Comparison image of Canon SD4500 IS and Nikon S4000 Cameras
Canon SD4500 IS and Nikon S4000 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
Canon SD4500 IS
or the
Nikon S4000 ,
including hyperfocal distance.
