Pentax K10D has a
10.0MP APS-C (23.5 x 15.7 mm ) sized CCD sensor . On the other hand, Samsung HZ35W has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the K10D and HZ35W sensor size comparison.
Sensor Size and Resolution Comparison image of Pentax K10D and Samsung HZ35W Cameras
As seen above, Pentax K10D has a 13.1x Larger sensor area than Samsung HZ35W. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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 K10D
or the
Samsung HZ35W ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C versus 1/2.3-inch),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
