I trust Leica optics which I know performance. This little device will allow me to take pictures in museums where the works are exhibited behind glass because this device has a setting that does not take stock of the glass and thus to have a proper image. AMAZING WHAT CAN DO ALL THIS SMALL APPLIANCE: correct photos and videos; even the sound is OK even if it is not in stereo. It allows videos quite acceptable. AND IS EVERYTHING IN A POCKET!
