Canon 1Ds MIII has a
21.0MP Full frame (36 x 24 mm ) sized CMOS sensor . On the other hand, Sony NEX-5T has a
16.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features Bionz processor.
Canon 1Ds MIII's sensor provides 5MP more than Sony NEX-5T'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 1Ds MIII and NEX-5T sensor size comparison.
As seen above, Canon 1Ds MIII has a 2.4x Larger sensor area than Sony NEX-5T. 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
