Have you ever heard of lens fungus? Most of you must have never heard of such a thing. But, those who know about it do admit that there can be nothing quite as annoying as discovering the fact that your favorite lens has become a breeding spot for the fungus.

Depending on the climate of where you stay, the lens fungus could actually be a huge issue and therefore it is best to familiarize yourself with it.
