Leica X2 has a
16.0MP APS-C (23.6 x 15.8 mm ) sized CMOS sensor . On the other hand, Panasonic LX100 II has a
17.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine processor.
Below you can see the X2 and LX100 II sensor size comparison.
Sensor Size and Resolution Comparison image of Leica X2 and Panasonic LX100 II Cameras
As seen above, Leica X2 has a 1.7x Larger sensor area than Panasonic LX100 II. 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.
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
Leica X2
or the
Panasonic LX100 II ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C versus Four Thirds),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
