Dear All,

Just wondering how do you keep your lenses in a dry cabin? Straight up or lie down? If straight up, which part of the lens on top? Will these make any difference?

1. Straight up, lens mount at bottom


2. Straight up, lens filter at bottom


3. Lie down


Of course we'd put the front and rear caps on ;)

Searched on the internet but couldn't find any reference about this. Might get some inputs from here I guess.

Thanks and Cheers!

Its like "Do you eat ur mashed potatoes 1st b4 ur steak or do u eat ur steak 1st or do u eat them both together."
Answer: they all end up in the same place anyway, in ur tummy.


The purpose of the dry cabinet is to provide a dry environment for ur items, whether u suspend the lenses on a thread inside them or stack the lenses on top of each other is entirely up to u.

The key is to avoid scratches and maximise your spare. I think it's designed to put it standing up, unless you have a big lens then no choice to lay it flat. Personal preference is to put it with the lens cap on the rear elements. But i guess no harm putting opp direction with the lens cap on the front since you likely will have a UVfilter as well.

For long lens like 400 f 2.8 and above must put it straight,coz the lens element is heavy and may cause the barrel to diform in a long time is let it led down.

For me it's straight up with lens mount at bottom for short lens, and lie down for long lens

front element face down. cos usually front element is bigger, thus a lower center of gravity, otherwise it'll just tip over.

Best to put the lens vertically, my logic being:
1. Glass is supercooled liquid, it will continue to flow, and if you happen to keepyour lens in the cabinet for say 10 years, there may be noticeable distortions. Check out very old mirrors or those from IKEA after 2 years.
2. Lubricating oil in the lens will also flow, sometime solidify. If flow, better to flow down the barrel than across the lens. If solidify, better to have regular stiffness all round than to have the oil lumped in a clump at the "bottom" of the resting lens.

Of course, if you move your lens around very often, these are just 'bs'. But for cold storage, it may be significant.

It is likely that this kind of effect is in terms of a log scale for the time axis, like 10, 100, 1000 years. So, dun worry so much about it la. At our local room temperature of say 24 to 28 deg, there is nothing to worry. If you leave the lens in the car for long period, I think the rubber grip, the lubricant would go first before the lens starts to deform to affect the performance.

A normal size one will do actually. Without the front hood, the lens isn't really that long. i actually did the measurements once when i was contemplating the lens.

i keep all my lenses pointed down, except one telephoto lying flat.

I keep them straight up, lens mount at bottom. For teles, lie down of course. The reason why I do this is because when I buy Canon lenses, I noticed that's how they position them from within the box, in the vertical position. :)
