Pentax E70 has a
10.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Pentax I-10 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Prime processor.
Below you can see the E70 and I-10 sensor size comparison.
Sensor Size and Resolution Comparison image of Pentax E70 and Pentax I-10 Cameras
Pentax E70 and Pentax I-10 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
Pentax E70
or the
Pentax I-10 ,
including hyperfocal distance.
