Hi people My question in a nutshell, is I have a 5D and over last 6 months I took it to Canon for sensor repair twice, and now I need to clean it again! It's too costly to take it back there... I tried the dust blower method as well as direct sensor cleaning e.g. special brush...both did not work with me. So I am sure many of the professional members here in photo.net have worked out some methods around cleaning the sensor... Please Enlighten me!
