I followed the discussion about moisture with interest seeing as I live in FL and do not want fungus in my lenses. So much so that I purchased some silica packets and a water tight cooler. however this lesves me with a question: how many 3 gram silica packets should I put in the cooler? Another question: Should I squeeze the flashes and other non camera things in there as well?

At one point in my professional life we were able to buy desiccant as loose crystals. Theses were used to keep the air in wave guide dry as part of a small air pump assembly. The neat thing was that when dry they were blue but turned pink when saturated. When that happened a 5 minute run in the microwave oven dried them out so they could be reused.

Well, I do not live in Florida, I live in Michigan, although I do go there every year to visit my 2 Children and Grandchildren, usually January-March. I read about the hazards of condensation with my DSLR D3300 and my 4 Lens, so to Amazon I went, and purchase a "large package" of small Silica gel packs, and I have "Sprinkled" them into my LoPro Camera Bag. I am hoping this will prevent any moisture from accumulating on my Camera or Lens.

Although you, as a year around Florida resident have a different set of circumstances, very High humidity from May-September and the issue of going from Air Conditioning to a hot humid outside climate, and then returning to that Cool climate once again. You must climatize or equalize climate environment of your equipment before you expose it to the extreme climate changes.

Now as a relative rookie to DSLR Photography (3 years), I am just expressing ideas I have gathered on this particular subject of Camera and lens care in extreme Climate change.

There are many "You-Tube" Videos that will deal with this subject, as well as "Professional Photographer's" that have written on this subject.

Hoping my thoughts have been helpful, at least a litte bit!

I live in Miami; and because my house has central air, I don't have that problem.

Would never discourage you, Mike, but I live in SW FL (Naples area) year around and have never experienced your concerns with any of my camera equipment. My equipment stays in my Den when I am not using it so it stays cooled and dried - with no problems showing up when I take it outside.

But - as an aside - I do leave my ZS50 in the map pocket of my car 27/7 and have done so continuously for the past 3 years and it shows no sign of weather negativity in any manner and continues to perform perfectly, including possible battery problems.

Although, do you take precautions when leaving your "Air-Conditioned" home and exposing your Camera and Lens to the "High Humidity" outside?
How do you protect your equipment from the negative effects of Condensation?
How do you "Equalize" the Climate environment?

So then what causes fungus?

Air tight is it?

Kmgw9v Loc: Miami, Florida

All I said was that although I reside in Miami, I don't have the problem of fungus on my gear.. I attribute that to keeping the gear in an air-conditioned environment.

You might try a different way to absorb the moisture with a system I use purchased from Wal Mart, ,I don't have one on hand to tell you the brand but its a small two layered container that has a silica layer that absorbs the moisture and deposits it in the lower level of the little bucket, inexpensive and amazing how much water it takes out of the air.
