Panasonic TS4 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features Venus Engine FHD processor. On the other hand, Canon 1D MIII has a
10.0MP APS-H (28.7 x 18.7 mm ) sized CMOS sensor .
Below you can see the TS4 and 1D MIII sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic TS4 and Canon 1D MIII Cameras
As seen above, Canon 1D MIII has a 19.4x Larger sensor area than Panasonic TS4. 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 TS4
or the
Canon 1D MIII ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus APS-H),
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.
