Pentax RS1500 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Canon SX230 HS has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features DIGIC 4 with iSAPS technology processor.
Below you can see the RS1500 and SX230 HS sensor size comparison.
Sensor Size and Resolution Comparison image of Pentax RS1500 and Canon SX230 HS Cameras
Pentax RS1500 and Canon SX230 HS 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
Pentax RS1500
or the
Canon SX230 HS ,
including hyperfocal distance.
