Those of you who are fairly new to digital photography and/or have never had an interchangeable lens digital camera may not understand that the sensors on these things are dust magnets. Having been a pro photographer when real full frame sensors arrived in SLR's, I can attest to how much time I spent cleaning dust from my then state-of-the-art Canon 5D. It appears that every camera on the market now boasts sensor self-cleaning, that is all, except the sensor on our X5's. Has anyone here found a best way to clean these things? I'm guessing Sensor Swabs and fluid...but I'd be open to hearing any other techniques.
