The AF speed is good and is little cause for criticism. The sharpness is ok and enough for small prints from. Contrasts and colors are good. Fringing be almost completely corrected for JPEGs with the camera in RAW format, however they fall on clear, especially from aperture F8 at wide angle. In zoom range they are virtually non-existent.
Why is the lens but not to my favorites Compact?
The resolution at wide angle up to scratch. At about 14-18mm lost the edges too many details. In the center still ok, the resolution drops to edge clear. The smaller the aperture, the greater the drop. Contrary to other reviews I could not find this effect in 42mm in this form.
It is too big a compromise. The lens comes only then used when the M10 necessarily in the jacket pocket.
Better make it the Panasonic H-FS1442AE ASPH. For just 200 euros, the imaging performance is available much better and over all focal lengths and apertures. The build quality is not quite as high, but the Panasonic is very easy and relatively compact.
