Panasonic FS15 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Panasonic LX3 has a
10.0MP 1/1.63-inch (8.07 x 5.56 mm ) sized CCD sensor .
Below you can see the FS15 and LX3 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FS15 and Panasonic LX3 Cameras
As seen above, Panasonic LX3 has a 1.6x Larger sensor area than Panasonic FS15. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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
Panasonic FS15
or the
Panasonic LX3 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus 1/1.63-inch),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
