Canon T7 has a
24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 4+ processor. On the other hand, Canon 1100D has a
12.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor and features Digic 4 processor.
Canon T7's sensor provides 12MP more than Canon 1100D'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 T7 and 1100D sensor size comparison.
Canon T7 and Canon 1100D 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.
DxOMark Sensor Scores
Both Canon T7 and Canon 1100D 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, T7 has scored 71, 9 points higher than 1100D.
