Nikon D4s has a
16.0MP Full frame (36 x 23.9 mm ) sized CMOS sensor and features Expeed 4 processor. On the other hand, Panasonic ZS40 has a
18.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features Venus Engine processor.
Below you can see the D4s and ZS40 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon D4s and Panasonic ZS40 Cameras
As seen above, Nikon D4s has a 30.7x Larger sensor area than Panasonic ZS40. 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
Nikon D4s
or the
Panasonic ZS40 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Full frame versus 1/2.3-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.
