Panasonic FH8 has a
16.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Samsung TL225 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor .
Below you can see the FH8 and TL225 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FH8 and Samsung TL225 Cameras
Panasonic FH8 and Samsung TL225 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 Samsung TL225 has 32% larger pixel area (2.31µm 2 vs 1.74µm 2 ) compared to Panasonic FH8, 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 FH8
or the
Samsung TL225 ,
including hyperfocal distance.
