16.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Bionz processor.
Below you can see the 60Da and NEX-6 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 60Da and Sony NEX-6 Cameras
As seen above, Sony NEX-6 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 NEX-6 ,
including hyperfocal distance.
