Both Sony A68 and Canon T7 have APS-C sized 24.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the A68 and T7 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A68 and Canon T7 Cameras
As seen above, Sony A68 has a 1.1x Larger sensor area than Canon T7. 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
Both Sony A68 and Canon T7 sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, A68 has scored 79, 8 points higher than T7.

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 A68
or the
Canon T7 ,
including hyperfocal distance.
