Canon G1 X has a
14.0MP 1.5-inch (18.7 x 14 mm ) sized CMOS sensor and features Digic 5 processor. On the other hand, Samsung HZ25W has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor .
Below you can see the G1 X and HZ25W sensor size comparison.
Sensor Size and Resolution Comparison image of Canon G1 X and Samsung HZ25W Cameras
As seen above, Canon G1 X has a 9.4x Larger sensor area than Samsung HZ25W. 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
Canon G1 X
or the
Samsung HZ25W ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1.5-inch 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.
