Sony A37 has a
16.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor . On the other hand, Canon 600D 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 A37 and 600D sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A37 and Canon 600D Cameras
As seen above, Sony A37 has a 1.1x Larger sensor area than Canon 600D. 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 A37 and Canon 600D 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, A37 has scored 75, 10 points higher than 600D.

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 A37
or the
Canon 600D ,
including hyperfocal distance.
