I have since added another very effective tool to my sensor cleaning arsenal, on top of that little $5 brush. It is made by Hakuba, the ‘Lens Pen Pro’, and sells for all of $10, coming with both a retractable brush and less pliable spongy end when the going gets tough. It has far better reach than the film brush. In fairness, I have had few sensor dust problems with the 5D, but then again I live in a part of the USA where prevailing humidity levels are average; I cannot help wondering whether those in dry, static bearing, climates are more affected?<\/p>\n
