P. J., I dropped one loong ago, before the days of circular polarizers - 
and it delaminated some right after the impact, but stopped despite 
being kept in a drawer for 12+ years. Found it in january, still looking 
the same - just a semi circle delaminated radiating from the ding in the 

Moisture is a problem - but the pesky filter was stored with silica, 
along a lens and some other bits and filters and the rest is looking the 
same as before. The BH pair - circular polarizers, 52 & 58mm - is 
outside, in the bag since before the P adapters were released and is 
still perfect.

Not a huge setback, but annoying. I'd rather understanding, so it 
doesn't happens again.
