Canon 20Da has a
8.0MP APS-C (22.5 x 15 mm ) sized CMOS sensor . On the other hand, Canon XC10 has a
12.0MP 1' (12.8 x 9.6 mm ) sized CMOS sensor and features DIGIC DV5 processor.
Below you can see the 20Da and XC10 sensor size comparison.

As seen above, Canon 20Da has a 2.7x Larger sensor area than Canon XC10. 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 20Da
or the
Canon XC10 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C versus 1'),
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.
