Panasonic ZR1 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features Venus Engine V processor. On the other hand, Panasonic FH25 has a
16.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features Venus Engine VI processor.
Below you can see the ZR1 and FH25 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic ZR1 and Panasonic FH25 Cameras
Panasonic ZR1 and Panasonic FH25 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 ZR1 has 32% larger pixel area compared to Panasonic FH25, 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 ZR1
or the
Panasonic FH25 ,
including hyperfocal distance.
