You can find a lot of "how to..." articles on lens fungus on the net. But I still curious about your personal opinion about how to prevent lens fungus. I live in Miami and I shoot a lot of destination weddings in the Caribbean where humidity is high all around the year. Therefore lens fungus is something I am concerned about. - I keep my gear air conditioned all the time. - when I am outside I always take them out of the leader case so they get fresh air. What do you think?
