12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features Venus Engine V processor.
Below you can see the TX10 and FZ35 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony TX10 and Panasonic FZ35 Cameras
Sony TX10 and Panasonic FZ35 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
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
Sony TX10
or the
Panasonic FZ35 ,
including hyperfocal distance.
