Nikon D200 has a
10.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor . On the other hand, Canon SX510 HS has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features Digic 4 processor.
Below you can see the D200 and SX510 HS sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon D200 and Canon SX510 HS Cameras
As seen above, Nikon D200 has a 13.3x Larger sensor area than Canon SX510 HS. 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 D200
or the
Canon SX510 HS ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C 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.
