p.1 #1 · Lens fangus protection


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?

Assuming you don't collect lenses you should be able to store yours in a cabinet or small closet - for that amount of space you don't need a dehumidifier. Just a couple of rechargeable silica gel packs would easily do the job.

I even keep one in my camera bag.

I use ones like these: http://cgi.ebay.com/Dessicant-Silica-Gel-40-Gram-Keep-Your-Coins-Dry_W0QQitemZ390103863232QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item5ad4008fc0

From October to May (the heating season), our home is quite dry. Then, Jun to early September it's the A/C season....again, the amount of moisture indoors is not excessive. All in all, I haven't felt any neeed to go into additional humidity control measures. However, I should get some silica gel to place into cases holding a few lenses which are not used frequently.

Take your lenses out and use them. UV light whoops some fungus butt.

. NJ doesn't need dehumidifiers to store lenses, especially this time of the year. As the heating is coming on, the humidity indoors is dropping rapidly. It ain't the tropics :-)

Yes it is in cabinet but not hermetically closed cabinet and as you may read in post this room gets about gallon of water per 8 hours in air. I am not much into climate or biology and can't say if this is OK to not get fungus in lens, however if it is than I wouldn't be covered by my insurance. I believe Canon warranty also gets void for same reason

Climate changing as you might know, also you wouldn't say this if you stay in NJ last week No it is not good for heat yet 65-70F during day and rain, but also not as comfortable for AC already.

I am sure that I never been in worse/humid/rainy weather as last Sat night for 10 years I am in NJ. It was also last day of October!!! with 73F outside 7PM.
And believe me I been in Florida and I know what is humid means.

Store them in kitty litter works like a charm. They say if you ever get your cell phone wet put it in kitty litter and it dries it out

Right, I am sure I wouldn't need this box when AC or heat is On. I am just getting very uncomfortable, looking on gallon of water inside of this box every 8 hours Selica needs to be replaced as you might know, it will not protect forever.

That is unless you put it in a tray and then put kitty litter in said tray and your cat finds the tray!

Have had many lenses in the wet/humid Pacific Northwest for over 30 years and never had mold on a single lens.

Fungus prefers to grow high heat and high humidity. In the PNW, humidity is high when its cool, but seldom high and warm. 90 degrees and 90 percent humidity is a great formula for growing fungus.

Fangus protection? Just keep them in the light of the sun, away from vampires

Seriously, until the humidity gets above 60% you shouldn't need to worry about mold or fungus. The amount of water the dehumidifier pulls out the air isn't a very good way to measure relative humidity. Get a weather station which shows relative humidity. Wireless weather stations which show indoor / outdoor weather and have clocks sync'd by radio to the master atomic clock for precise time are now relatively inexpensive.

To me it is not big overkill to buy $140 dehumidifier to protect $20K of optics. Besides there is some other use of this thing too. Also humidity as I specified above become brutal lately in NJ area, especially makes me worry in between seasons when no heat or AC is on.

I live near the ocean in a foggy climate, and I run a de-humidifier all winter and spring, and sometimes in summer if it stays foggy for a few days. I get about two gallons a day in my de-hu and I have a small house.

Most of the lenses I've had that got fungus were cheaper zooms that had spent time in the wet tropics. Silica packs are useless in the rainforests I was shooting in. Cleanliness was also challenging. I have a couple of Canon paperweights as souvenirs of my travels.

Other photographers said keeping the lenses clean and warm seemed to be a good preventative. And watching out for internal dust or the beginnings of the fungus threads, of course. At the first sign of something inside you've got to send the lens in for immediate servicing.

At home I do use silica inside the cases, but the de-humidifier does the heavy lifting. Well worth the $100 spent at Sears.

Where I live relative humidity is normal at 90+% so you really have to buy a electronic dry cabinet to maintain 30-60% relative humidity. I got two for the big whites and the small black lenses + bodies.

They're worth the purchase vs paying to have your lens cleaned/scrapped.

I don't disagree. I lived in Manila for 11 years and used dehumidifiers in addition to air conditioning and would dump them 2-3 times a day (several gallons of water).

The point I was making was that without some means of measuring measuring humidity quantitatively you really won't know how high it actually is. I'm a few hundred miles south of you getting the same crappy weather a day before you and haven't seen the indoor humidity go above 50%. Right now it is 44%.

From Wikipedia:
The dew point is associated with relative humidity. A high relative humidity indicates that the dew point is closer to the current air temperature. Relative humidity of 100% indicates the dew point is equal to the current temperature and the air is maximally saturated with water. When the dew point remains constant and temperature increases, relative humidity will decrease.

So while the humidity might be 90% outdoors at 50 degrees F when you bring the same air inside the house and warm it up to 70 degrees F the relative humidity drops.

+1 Bad weather doesn't necessarily affect humidity that much (esp. indoors). This is New Jersey we're talking about, it simply doesn't get that humid there at this time of the year.

Rubbermaid bucket + Saran Wrap + dessicants

Problem solved.
