15 years ago, on a whale-watching trip off the coast of Massachusetts, the rocking sea caused my father's camera to roll off of a table and hit the floor lense-first. Although the lense looked ok, the filter glass was shattered and the ring was bent out of shape. It was impossible remove it and it was also hard to tell if there was any damage to the lense barrel it's self.
It stayed that way until I inherited it a few days ago and figured, I could try and remove it my self. I had nothing to loose. As it turns out, with a little patience, it's actually quite easy.

All you need is different sizes of plyers. I used a paire of long nose plyers and a pair of spoke wheel plyers. Most importantly you need safety goggles.
