Sony A200 has a
10.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor . On the other hand, Leica M11 Monochrom has a
60.0MP Full frame (36 x 24 mm ) sized Monochrome BSI-CMOS sensor and features Maestro III processor.
Leica M11 Monochrom's sensor provides 50MP more than Sony A200'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 A200 and M11 Monochrom sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A200 and Leica M11 Monochrom Cameras
As seen above, Leica M11 Monochrom has a 2.3x Larger sensor area than Sony A200. 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. Sony A200 and Leica M11 Monochrom sensors have been tested by DxO and the results show that M11 Monochrom has a better overall score of 100, 37 points higher compared to A200's score of 63.

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
Sony A200
or the
Leica M11 Monochrom ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C 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.
