Resent extremely wet/humid weather in my area (NJ) pushed me to buy dehumidifier for lens protection reason. I ran it last night and it gets about 2-3 liters of water per about 8 hours of run in small room I am storing my lenses.
Scary fact even I am not in tropics area, especially since my lens insurance doesn't cover molds related issues (verified)....

What about you?

I have been shooting in Thailand and S.E.Asia for 25 years without any fungus problems. And there is really really wet/humid compared to any parts of US. All the Thai photographers I'm shooting with, have been shooting and keeping their lenses in that environment their whole life without any problems

I would say yes it is safe in general and I believe you, but also not as expensive to get this box to make sure it is Ok with humidity in storage room. It would be much more trouble to get fangus inside $3-$5k lens and no support from insurance ...

That was the highpoint for the month! The low was 20% & the average 50.2 %. I think you are worrying unnecessarily.

Not to worry, you have an early warning system: you'll start growing fungus and mold before the camera does because you are a better growth medium

You should worry more about what happens in winter when you bring your freezing cold camera from outdoors into the warmer air indoors. The moisture from the higher relative humidity indoors can cause condensation inside the lens and other camera surfaces. For that reason its best to seal the camera in an airtight bag and let its temperature reach that of the room before opening and operating. Same for stuff fresh off the UPS truck in January.

If you want to ease your worries get a pair of hydometers that will report the % relative humidity for your storage room. Use these to verify that your dehumidifier is keeping the space between 40% and 60% relative humidity.

I don't have the link off hand for reference but the majority of fungus grows in sustained 60% or higher relative humidity. Fungus is also more likely to grow on equipment that is both stored in a high humidity environment and is not used very often. Also, there are different types of fungus, though not as common, that thrive at very low humidity (30% and lower primarily).

Maybe San Francisco would be good, should be low in humidity?

I don't think you are getting this page information correctly, it is also saying Low -49.5 °F for temperature. I don't recall this temperature this year. What you saw is historical, probably in 100 years old period or something.

No mate, I'm quoting the monthly info. for October 2009. Honestly, I think you can relax, your lenses aren't in imminent danger of fungus attacks.

The gist is: you are not in a high humidity area, your lenses aren't likely to be invaded by fungus.

It is relative to 100 or 500 years period but not to the climate shifts we are witnessing lately and I some provided facts to you. Besides it could be dry outside and humid inside, if you read this thread you will figure that many people concerning about same. My concern is more related to the cost of lens and no insurance coverage for mold damage.

Breitling, I have seen humid indoor enviroments do a lot of damage. I think you are smart to be concerned. I am in the remodeling biz and have attended seminars on mold. The humidity level inside the home can vary quite a bit even within the same neighborhood. Factors like damp crawl spaces, ground moisture, and improper ventilation can all contribute to high indoor humidity levels. If your furnace has a humidifier on it you can turn that down or off. My home maintains a very low 38% humidity level, but if yours is above 60% then I would take action to lower it. Your de-humidifier will probably be all you need, but as I've found out - better safe than sorry.

Sometimes a home can be over-insulated which can spike the indoor humidy levels. Too much wall/attic insulation and tight-sealing windows are some common culprits.

Excessive condensation on the inside of your windows when it's cold outside is a red flag. You're probably getting scared over nothing because most homes are fine, but it is worth investigating with expensive lenses like your 500 sitting around.

I'm not sure where the 100-500 comes in, again, I was quoting figures from October 2009 - figures you linked me to! You don't live in a high humidity area & lens fungus isn't likely to be a real problem. New Jersey isn't the Phillipines.

But suit yourself. If it makes you feel better to spend money on a de-humidifer etc. - go for it!

Dehumidifier is expensive... and it uses up electricity. If you store all your gear in a cabinet, why don't you just put some moisture absober like Damprid in the cabinet and open the window a bit to let the air in?

Leonid, don't get carried away with your de-humidifier scheme either. There is a danger to excessive dryness too. For one, you might desiccate all rubber rings and gaskets on your lenses. Furthermore, lubricants in your 500, 300 etc. might dry out and/or solidify/gum-up way prematurely resulting in failures of moving parts like focusing assembly. Lastly, many interior lens components like glass and fluorite elements are set in and stabilized in situ using a plastic sealant (caulking). A very bad news if that starts to dry out.

Is fangus better or worse than fungus?

From the Urban Dictionary:

Fangus

1. A pungent, clumpy substance that looks and smells quite disgusting to the average westerner. Certain cultures consider it edible, but none find it appetizing. It is only eaten by outcasts or by those who have little else to eat. However, a few affluent people still eat it despite its nausea-inducing flavor, to the dismay of more civilized citizens.

2. A bizarre Indian delicacy quite unpopular in the United States. It is served chilled and can contain curry, potatoes, and/or [...deleted].

I am resistant to the one who is arguing anywhere and anyplace without reason and facts. You or Vers etc on this forum are normally opposing any posts. So, what is new?

Correct, but that is covered by insurance or warranty ...
