Originally posted by stevebrot Before breaking out a sensor cleaning kit, consider the following...In the over twelve years that I have been shooting Pentax digital (K10D in 2007 followed by a K-3 in 2014), I have never once had to touch my sensor with any wet or dry cleaning kit. The rocket blower has been enough with no risk to the sensor. Of course, YMMV
I agree that the first option should always be a blower. As you say, YMMV because my K3 sensor had spots which only the cleaning kit could remove. I was only adding it as an option, not suggesting it as the first solution to try. Whether you have issues with dust may vary a lot depending on where you are. I live in an inland part of Australia, where the humidity can be very low and dust very pervasive. If possible, I try to minimise changing lenses. Sometimes I even take the K5 with a wide angle lens and use the K3 for the DFA 150-450.
