Sony A55 has a
16.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Bionz processor. On the other hand, Canon T6 has a
18.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 4+ processor.
Below you can see the A55 and T6 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A55 and Canon T6 Cameras
As seen above, Sony A55 has a 1.1x Larger sensor area than Canon T6. 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

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
Sony A55
or the
Canon T6 ,
including hyperfocal distance.
