Pentax W80 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Samsung HZ50W has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor .
Below you can see the W80 and HZ50W sensor size comparison.
Sensor Size and Resolution Comparison image of Pentax W80 and Samsung HZ50W Cameras
Pentax W80 and Samsung HZ50W 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. On the other hand, since Pentax W80 has 16% larger pixel area compared to Samsung HZ50W, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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 W80
or the
Samsung HZ50W ,
including hyperfocal distance.
