Originally posted by Ben_Edict Not if you are in a humid environment. The Phillipines, which show in your location signature are not a place, where I would store my lenses in photo bags. Keep them ventilated or, even you have really expensive and valauble glass, buy a dry cabinet for photographic gear. There have been several suggestions about those in the past.

Same here.
I'm glad we didn't start off our Pentax kits with expensive lenses because many of them grew mold and/or humidity issues in the first year due to temperatures here.
Now... I buy a regular supply of dry packs(desiccant) and keep some fresh ones in our bags at all times.
I also place our packs in a room with a dehumidifier when they are not in use.
It's been 4 years since we've had problems.
Good luck!
