Both Olympus XZ-1 and Panasonic LX5 have 1/1.63-inch sized 10.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the XZ-1 and LX5 sensor size comparison.
Olympus XZ-1 and Panasonic LX5 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.
DxOMark Sensor Scores
