Panasonic GF7 has a
16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine processor. On the other hand, Panasonic GF1 has a
12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine HD processor.
Below you can see the GF7 and GF1 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic GF7 and Panasonic GF1 Cameras
Panasonic GF7 and Panasonic GF1 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 GF1 has 31% larger pixel area (18.74µm 2 vs 14.21µm 2 ) compared to Panasonic GF7, 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 GF7
or the
Panasonic GF1 ,
including hyperfocal distance.
