Panasonic FZ300 has a
12.0MP 1/2.3 (6.17 x 4.55 mm ) sized CMOS sensor and features Venus Engine processor. On the other hand, Kodak AZ255 has a
16.0MP 1/2.3 (6.17 x 4.55 mm ) sized CMOS sensor .
Below you can see the FZ300 and AZ255 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FZ300 and Kodak AZ255 Cameras
Panasonic FZ300 and Kodak AZ255 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 FZ300 has 32% larger pixel area compared to Kodak AZ255, 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 FZ300
or the
Kodak AZ255 ,
including hyperfocal distance.
