i did a ton of travelling earlier this year and got my camera lenses
quite dirty at times. (did my best to keep them clean but i was in
crazy places...)

i wiped them gently with anti-static cloths but i didn't feel good
about it.

should i buy "Multicoated" lens covers (i believe a.k.a. Neutral
Density Glass Filters)? has anyone used them?

i own the Canon 30D, and so far all Canon lenses.

thanks, dave
