Re: Self repair
A more preferred method is to leave the lens on a window sill in strong sunlight for a few weeks. :rolleyes:
Both caps need top be off and something non flammable behind it in case the lens focusses the suns rays and sets your house on fire.:eek:
The UV should then revert the element to clear glass again.
I understand that the offending element is to the rear of the lens, so it makes sense to point that end towards the sun.
I've also seen it recommended to make a front lens cap out of tin foil, shiny side in, to double the effectiveness of the treatment.
Don't let the lens get to hot though as it may effect the optical cement.
Some folk claim have had success by using a UV-B tube instead of sunlight.

This methodology should clearly carry a health and safety warning due to the risk of inhaling particles of radioactive material from the resultant dust.

Also be sure you have been trained in the safe use of the manual post-driving or rock modification tool before attempting to use it. :D

What a waste! :eek: Obviously never heard of black and white...
