They say that it is a dry heat here in Arizona...and right they are. I have been struggling with dust getting onto my sensor and rearing its ugly head in some of my pics --mostly at smaller apertures (and when i bump up the contrast in PP). Like this: After I would turn the camera on and off a couple of times with a near-full to full battery to actuate the sensor clean/shake function...and hope it was all better. But lately I have noticed that the one spot in the upper RH corner of my shots is persistent, regardless of how many times I cycled the sensor shake function. Ruining this otherwise decent shot of Soda Lake Not wanting to miss any more opportunities I decided it was time to take the plunge and try to get the dust off the sensor. From my local camera store, I picked up a Jumbo Hurricane Blower (similar in size to Giottos Large Air Rocket blaster) to blow out any loose dust and LensPens SensorKlear II to pick up the stuck dust particles. I took a pic at f22 and upped the contrast to see what was on the sensor Eww :upset: Tilting the camera flange-side downward I tried some puffs with the blower Better for sure. If some puffs got most dust out, maybe more puffs from the hurricane would get them all and I wouldn't have to touch the sensor? :149: No dice A couple of deep breaths and I broke out the SensorKlear II. With the camera laying flat on a table and good light I could see some particles on the sensor. Trying to keep the touch on the sensor light, I appeared able to pick up (brush off?) the dust. Another test shot ...and Next time around I am not going to be so paranoid about cleaning it off...but it is a little scary.
