With its 40.9MP sensor, the M10 Monochrom should be able to record close to 5,200 lines per picture height. It comes extraordinarily close to achieving this, not just at ISO 160, but also much higher settings. With no colour demosaicing required to develop its raw files, the camera gives an extremely clean rendition of our test pattern at ISO 160, and it’s only at ISO 12,500 that noise clearly reduces resolution, to about 4,600l/ph. Even at ISO 50,000 we register 4,000l/ph, which is the highest theoretical resolution of the Typ 246.
On the right we show details from our resolution chart test pattern (above). Multiply the number beneath the lines by 400 to give the resolution in lines per picture height.…
