Both Samsung CL80 and Canon SX150 IS have 1/2.3-inch sized 14.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the CL80 and SX150 IS sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung CL80 and Canon SX150 IS Cameras
Samsung CL80 and Canon SX150 IS have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Canon SX150 IS has 1% larger pixel area (2.01µm 2 vs 1.99µm 2 ) compared to Samsung CL80, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
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
Samsung CL80
or the
Canon SX150 IS ,
including hyperfocal distance.
