Canon 5D MIV has a
30.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic 6+ processor. On the other hand, Canon 1000D has a
10.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor .
Canon 5D MIV's sensor provides 20MP more than Canon 1000D's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the 5D MIV and 1000D sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 5D MIV and Canon 1000D Cameras
As seen above, Canon 5D MIV has a 2.6x Larger sensor area than Canon 1000D. 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
Both Canon 5D MIV and Canon 1000D sensors have been tested by DxoMark. DxoMark 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. Of the two cameras that we are comparing, 5D MIV has scored 91, 29 points higher than 1000D.

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 5D MIV
or the
Canon 1000D ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Full frame versus APS-C),
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.
