Canon 450D has a
12.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor . On the other hand, Nikon D80 has a
10.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor .
Below you can see the 450D and D80 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 450D and Nikon D80 Cameras
As seen above, Nikon D80 has a 1.1x Larger sensor area than Canon 450D. 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
Canon 450D
or the
Nikon D80 ,
including hyperfocal distance.
