Canon 60Da has a
18.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 4 processor. On the other hand, Sony A65 has a
24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Bionz processor.
Sony A65's sensor provides 6MP more than Canon 60Da'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 60Da and A65 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 60Da and Sony A65 Cameras
As seen above, Sony A65 has a 1.1x Larger sensor area than Canon 60Da. 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.
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 60Da
or the
Sony A65 ,
including hyperfocal distance.
