The Dust-Aid is a effective way of removing most dust from your camera sensor.I have use it on both DSLR and my Leica M9 fullframe successfully.This product is kind of a anti-dote to the huge volume of products for cleaning DSLR sensors, its shockingly low-tech and works exactly as expected.REMEMBER: Always use a FULL FRESH CHARGED battery when clearing your sensor.!How it works, in the box you get a little sticky pad on a stick, its not very sticky, just enough to collect the dust without tearing out the sensor. So set your camera to cleaning and open the shutter, then start gently pressing the pad-on-the-stick in the one corner of the sensor, proceed "stamping" until you have covered the complete sensor. DO NOT try to wipe with this, only stamp straight down and up again.Once you have cleaned the sensor it is time to clean the dust-aid stick. The kid comes with a couple of cleaning pads, you use them by peeling back the tape on a cleaning strip and then tap the sensor cleaner on the cleaning strip, this strip is more sticky than the sensor pad, as you basically transfer the dust to the cleaning strip. I suspect using 3M blue low-tac tape would do the same trick, but since I have a stack of replacement cleaning-strips for $10 why take the chance with my sensor.These things are cheap and works well, the kit comes with a little red storage box, about 4 x 1.5 x 0.75 inches I put the box in a zip-lock bag to keep dust out, then jammed it in the bottom of the camera bag.Naturally sensors DO pick up nasty spots sometimes and there might be a time you need to do a wet-wipe cleaning, but the dust-aid will clean regular dust very easily, it is a great travel solution for giving your camera a once-over at night when on the road.A word on dust, the dust you see in the images are generally sitting on the surface of the glass protecting the chip, the dust is removed from the sensor by a small distance, because of that distance, dust is more noticeable when using small apertures, you can see dust easy if you do a test shot at f.22 or f.16 - at large apertures like f.1.4 dust will be less visible, but just as annoying if big enough to be seen. I am too lazy to clean each day, but there is nothing like a freshly cleaned sensor.Highly Recommended.
