Pentax K-50 has a
16.0MP APS-C (23.7 x 15.7 mm ) sized CMOS sensor and features PRIME M processor. On the other hand, Canon 4000D 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 K-50 and 4000D sensor size comparison.
Sensor Size and Resolution Comparison image of Pentax K-50 and Canon 4000D Cameras
As seen above, Pentax K-50 has a 1.1x Larger sensor area than Canon 4000D. 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 Pentax K-50 and Canon 4000D 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, K-50 has scored 79, 16 points higher than 4000D.

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
Pentax K-50
or the
Canon 4000D ,
including hyperfocal distance.
