Canon 750D has a
24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features DIGIC 6 processor. On the other hand, Canon 350D has a
8.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor .
Canon 750D's sensor provides 16MP more than Canon 350D'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 750D and 350D sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 750D and Canon 350D Cameras
Canon 750D and Canon 350D 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 750D and Canon 350D 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, 750D has scored 71, 11 points higher than 350D.

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 750D
or the
Canon 350D ,
including hyperfocal distance.
