Canon T8i 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 350D has a
8.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor .
Canon T8i'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 T8i and 350D sensor size comparison.
Sensor Size and Resolution Comparison image of Canon T8i and Canon 350D Cameras
Canon T8i 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.
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 T8i
or the
Canon 350D ,
including hyperfocal distance.
