Pentax E85 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Sony WX70 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features BIONZ processor.
Below you can see the E85 and WX70 sensor size comparison.
Sensor Size and Resolution Comparison image of Pentax E85 and Sony WX70 Cameras
Pentax E85 and Sony WX70 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 E85 has 32% larger pixel area compared to Sony WX70, 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 E85
or the
Sony WX70 ,
including hyperfocal distance.
