Panasonic G7 has a
16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor . On the other hand, Panasonic G10 has a
12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine HD II processor.
Below you can see the G7 and G10 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic G7 and Panasonic G10 Cameras
Panasonic G7 and Panasonic G10 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 G10 has 31% larger pixel area (18.74µm 2 vs 14.21µm 2 ) compared to Panasonic G7, it has larger pixel area to collect light hence potential to 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 G7
or the
Panasonic G10 ,
including hyperfocal distance.
