Below you can see the SX210 IS and E70 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon SX210 IS and Pentax E70 Cameras
Canon SX210 IS and Pentax E70 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the 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 SX210 IS
or the
Pentax E70 ,
including hyperfocal distance.
