Both Canon SX150 IS and Leica V-Lux 30 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 SX150 IS and V-Lux 30 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon SX150 IS and Leica V-Lux 30 Cameras
Canon SX150 IS and Leica V-Lux 30 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
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
Canon SX150 IS
or the
Leica V-Lux 30 ,
including hyperfocal distance.
