I would like to know about the way you store your lenses.

I keep them on shelves. Part in a library part on a big shelf attached to a wall.
I try to keep them in the most dry part of the house. And in a place where there is good light

So fat I stored them vertical (sitting on the mount part, for most lenses except for a few big ones who sit on the front part as it's larger).
And with the caps on, to prevent dust to fall on the lenses.

But I am not sure that this is the best way. I think that I should remove the caps. At least periodically. But having the lenses vertical does not help, because the upper part will gather all the dust (and we know that dust is one of fungus' preferred food).

So I was thinking of building something with the wood, that may help to store the lenses horizontally without rolling.
Something like the things that hold the wine bottles, but simpler.
This way I could periodically remove the caps and have the inner part of lens receive some healthy light without collecting too much dust.

So, how do you store your lenses?

I am storing them in big plastic boxes without caps. They lie on their side, not on the front or back. Plastic boxes contains water remover chemical it keeps humidity always around 35%.

Benefits ?

No dust inside in box , humidity always around ideal value, and light can go to inside the lenses.

What chemical, and where do you buy it?

I have to find something similar here, I don't think we have the same brand of product available.
Not sure they keep it in supermarkets either.

What is that instrument you have there, does it measure humidity?

The one doubt I have about your system is: lenses need ventilation. Moving air. This is said by all recommendations I have read. You don't get much ventilation in a box.

Perhaps drilling holes in the boxes?

Hi!

This topic really gets interesting as soon as a collection grows.
I never thought about that, before I realised I had a few lenses...

I keep them in my study, where humidity is about 50% (depending on the season). I think that is a little too high, but it's the only place where I can store them.

They are in wooden shelves which grant ventilation and I store them horizontally. They don't roll if they are stored close together. BTW, the rest on the lens caps which serve as a kind of cradle for each lens.
The lenses "look" at my windows with open front but closed back (to prevent scratches there, since this would be a bad thing).

Looks like this:

Some lenses are missing, those are in my bag at the moment.

If humidity gets too high, we have a machine that filters out humidity, I think they are called "dehumidifiers".
Orio, you should be able to find chemical dehumidifying boxes in a hardware store. They are not expensive and work, once opened, for about half a year, depending on size.

This is part of my lens collection as it is currently stored, vertical and with caps on, from the left you can see the Carl Zeiss Jena and Pentacon lenses, then the Russian lenses that are big. On the far right, the only 4 Canon lenses that I own:

http://www.imageshock.eu/img/lenscoll1.jpg

Sorry for the picture quality, it is 1600 ISO and almost wide open, as I am not feeling very well I did not care about mounting the tripod, I will take a better picture one of these days.

Yes there is a humidity meter, if air is dry enough don't need any moving air.

Orio, dealing with humidity, dampness and condensation problems in buildings is a part of my job. I agree with Attila, up to a point. Fungus will not germinate without dampness (and sometimes it needs darkness too). Moving air is not vital as long as the air is always dry, but keeping it dry is not easy. Humans create moisture just by breathing. The reason people recommend good ventilation is that it's often the best way to get rid of moist air.

But there's another factor - temperature. Cool air cannot hold as much water vapour as warm air, so when warm and humid air becomes cooler it has to dump the water vapour somewhere, and this happens on the coldest surfaces first. This is why in winter you get condensation on cold windows. Try to keep all your equipment at normal room temperature. If you store anything near a cold wall or window there is a danger it could become colder than the air in the room and so attract moisture. The really dangerous time is when you bring a lens (or camera!) back into a warm humid room after being outside in cold weather. It will become covered in condensation, both inside and out. It needs to equalise temperature in a well ventilated place, so NOT in the camera bag!

Thanks, Peter!
Very useful information!

Perhaps you can answer a question I have been thinking about for quite a while.

If you have a humidity of 50% in a 25°C warm room, does that mean that there is effectively more water than in a room with 18°C and 50% humidity?

If yes, is it "better" (e.g. for lenses) to be stored in the second room?
