How do you guys protect your bodies when exposed to a lot of dust & pollution? The first obvious step that comes to mind is not changing lenses often. What else?
I have a 40D which is mildly weather proofed, but I know taking it to extremely dusty places (I'm specifically referring to dirty urban centers & slums in India) and dust will inevitably enter.
Would an upgrade to a 1d Mk II or a 5d Mk II or something help?
Is there anything I can do? Gaffer tape any openings? Suggestions?
