We all know that horrible feeling when you get home after a long trip and start going through your images, only to find that each one of them has a big dust spot on it. In the field I carry a rubber blower to try to keep the sensor clean, and at times I turn on the camera's cleaning mode which does that crazy shake. That is all I do. Many years ago I bought some sensor cleaning kit at Photo Plus and totally smudged my sensor, I learned my lesson. Since that incident I will not touch the sensor - I send my cameras out to have them professionally cleaned. The great news is that the Sony a1 has solved some of the problem with its protective curtain, which I am very grateful for.
Is there someone out there brave enough to clean your own sensor, and what do you use?
