Panasonic ZS7 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features Venus Engine HD II processor. On the other hand, Panasonic ZS10 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CMOS sensor and features Venus Engine FHD processor.
Below you can see the ZS7 and ZS10 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic ZS7 and Panasonic ZS10 Cameras
Panasonic ZS7 and Panasonic ZS10 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 Panasonic ZS7 has 16% larger pixel area compared to Panasonic ZS10, 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
Panasonic ZS7
or the
Panasonic ZS10 ,
including hyperfocal distance.
