Panasonic FZ35 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 FZ100 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 FZ35 and FZ100 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FZ35 and Panasonic FZ100 Cameras
Panasonic FZ35 and Panasonic FZ100 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 FZ35 has 16% larger pixel area compared to Panasonic FZ100, 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 FZ35
or the
Panasonic FZ100 ,
including hyperfocal distance.
