Panasonic GF2 has a
12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine FHD processor. On the other hand, Leica M Typ 240 has a
24.0MP Full frame (36 x 24 mm ) sized CMOS sensor .
Leica M Typ 240's sensor provides 12MP more than Panasonic GF2's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the GF2 and M Typ 240 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic GF2 and Leica M Typ 240 Cameras
As seen above, Leica M Typ 240 has a 3.8x Larger sensor area than Panasonic GF2. 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
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It 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. Panasonic GF2 and Leica M Typ 240 sensors have been tested by DxO and the results show that M Typ 240 has a better overall score of 84, 30 points higher compared to GF2's score of 54.

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
Panasonic GF2
or the
Leica M Typ 240 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Four Thirds versus Full frame),
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.
