IŽd like to ask what do you think about these "unusual" particles on the Leica S2 sensor, are they dust particles, some defect on sensor? Images bellow are from Leica S2 camera which IŽam going to buy from one FM member. Cropped 100% from DNG file. He tried to clean the sensor with sensor swabs and the dots are still there after using 3 sensor swabs. Maybe really small dust that's very stuck?? They look different from other dust particles but I donŽt think they could be some defects on the sensor, Leica has very tight output quality control so the sensor would not go out from factory? What do you think? Camera is almost in new condition with about 1400 auctuations but used&without warranty.
