[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]I clean a lot of sensors, maybe ten a day including the dreaded D600 oil issue. Use a blower with a lot of thrust to blow the dirt/dust off the sensor; start by holding the camera mount down then work from the outside of the mount into the shutter region. Whatever mode your camera has to clean the sensor engage that to open the shutter and blow off the sensor a few times. Put one and at most two drops of sensor cleaning fluid on the correct size swab(4/3, aps-C, H, FF) and sweep the swab in one direction with a moderate/light touch across the sensor maybe twice. You should be fairly quick as the fluid is essentially a highly volatile alcohol/ether/ketone mix. Blow off the sensor again. To confirm you got the dust and oil take an image with a normal to telephoto lens set to infinity and at around f16 of one of your slide sorting panels or some other plain light colored background using a high enough ISO that your shutter doesn't drag. Examine the resulting almost 18% gray image at whatever magnification makes sense for the images you create and repeat the cleaning process as needed until the offending detritus is gone. I hope this helps, the cover glass really isn't that delicate and if you can clean the glass of DR Summicron without scratching it then you can clean your sensor; just blow off the dust first so the only issue is oily grime that comes mostly from urban/polluted air. Dust will just blow off although electrostatic forces can make you think it won't. This once I wouldn't use Dr. Ted's lens cleaning method as even well laundered it probably isn't the best choice.
