I have hand straps that have moisture on them either from my body i.e sweat or condensation from jungles, forests and nature places (I almost only use them while trekking or hiking). I didn't bother washing these neoprenes materials and store them in "exposed" condition like what was suggest i.e removing caps and such. Weeks later, white fungus grow on them and I have to wash it. I have a friend who foolishly take out his drenched 70-200, remove the caps and let it "dry" outside the dry cabinet and within a week, the fungus grows so big that he had to send to Canon for professional cleaning. He had no idea why exposing them to open air will make it worst. He was thinking of superficial drying i.e he don't see water or moist means its ok to store it there.

As explained by another poster, indeed when we bring out, we expose them to natural elements like sunlight, movement, moisture etc. The constant movement and usage disturb the growth of fungus. Another easy to get fungus growing area is the handgrip of the body. If you have a battery grip, you can always try to take out the original 1 and leave it outside and see will it start growing or not.

If you leave it in sunlight, it shouldn't grow.... right?

But you can't leave it in sunlight 24/7

We have just gone through record rainfall here. It's rained virtually full time for 3 weeks with a few hours break and it's been hot and humid.

Do a search for 'fungus' in the For Sale section of POTN and see how many hits you get for sellers either advertising no fungus or buyers asking is there fungus on a lens.

Oh yeah, absolutely.

A dry cabinet is a wonderful piece of gear to own and inexpensive after a few L lenses.

A cheaper alternative is a rechargeable silica pack and pelican or other sealed type case, like the one currently in my case:

Also landed on:

Interesting idea!

What happens to a lens if it was in too dry conditions for too long? Ie 5-10% humidity as compared to the 40%?

u risk the lubricants among the mechanical part drying up.

I usually set to 45 RH. 40 I feel its too dry and when you take it out, you feel the moisture sticking to it like a dry sponge thrown inside water.

As Malsam said the recommended rh% is between 40% & 45% the dry cabinets have a dial and you just dial in the desired rh% and set it to that and it automatically keeps it there.

Lubricants shouldn't be affected if they aren't water based AFAIK. Problem with the dry cabinets is that you can't set a specific RH %, so you have to twiddle the dial and wait for it to stabilise, and even then there's a ~5% margin of error in the sensor so you have no idea of knowing whether you are actually at 45% or 40% or even 50%.

If you do a search on eBay you should get a lot of results as well.

The RH meters are now digital...some of them like mine are still using dials. Even if you don't know exactly how much to turn, the RH meter outside will show you after 24 hours of operations and you just readjust until you get it right. Most of the time you only need to do it once or twice.

Went on a cruise recently & the cabin only had 1 electrical outlet. I brought a lot of gear since I was going scuba diving & needed to charge a lot of different things. My wife also had priority when it came to blow dryer & curling iron. I found myself getting up in the middle of the night just to change out another battery. BS!

Next time I'll sleep much better. :D http://www.thegadgetbl​og.net …-pivot-point-power-strip/ (external link)

Brilliant! But how much does it weigh? With a thick 6-foot cord, I'd bet it's not light.


Geoff
All I want is a 10-2000 f/0.5L with no distortion that weighs 100 grams, fits in my pocket, and costs $300. Is that too much to ask?

I dont know yet but I will post as soon as it arrives this week. One could always cut it & replace the plug..... or get a sherpa.
