Nikon D70 has a
6.0MP APS-C (23.7 x 15.5 mm ) sized CCD sensor . On the other hand, Canon 350D has a
8.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor .
Below you can see the D70 and 350D sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon D70 and Canon 350D Cameras
As seen above, Nikon D70 has a 1.1x Larger sensor area than Canon 350D. 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.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Nikon D70 and Canon 350D sensors have been tested by DxO and the results show that 350D has a better overall score of 60, 10 points higher compared to D70's score of 50.

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 D70
or the
Canon 350D ,
including hyperfocal distance.
