I was wondering if anybody has had any experience in sealing lens
barrel against water and/or dust with any type of tape/sealant.
The area of the barrel that would need to be sealed
is away from the junction between rotating elements.
Does this sound too crazy?
I am considering purchasing a lens that might have problems like this.
Due to previous attachment of something unknown to the lens
(and related barrel modifications) the barrel might
not be sealed completely against moisture/dust.
This is not the actual lens but the one I am considering has
a similar sort of "modification". The plate might not have a perfect
seal:

Any thoughts?
Apart from what everybody else said: if you're not after a sealed lens,
but simply want the holes covered I'd use fitting screws (if the holes are
tapped) to fill them. If not, I'd take sanitary cement (is that the word:
I mean the transparent or white stuff you use to seal the gap between a
washbasin and the wall for instance). Apply sparingly, you don't want to
fill the lens with the stuff :o)
I never had the inclination to test it on lenses, but the stuff worked
wonders to make my car watertight!
