Canon SL3 has a
24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features DIGIC 8 processor. On the other hand, Canon 1000D has a
10.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor .
Canon SL3's sensor provides 14MP 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 SL3 and 1000D sensor size comparison.
Sensor Size and Resolution Comparison image of Canon SL3 and Canon 1000D Cameras
Canon SL3 and Canon 1000D have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the 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 SL3
or the
Canon 1000D ,
including hyperfocal distance.
