they sell lens. I don't think the lens will sit in the shelves for months. Most cameras shops that I know tend to stock only fast-moving lenses.

I lived in a serviced apartment and have my air-condition running for my dogs 24-7 but still used a dry cabinet for my cameras.

shop with aircon has a humidity of about 40-55%. that's good enough for storage purpose.

Actually they DO grow fungus. The humidity in some central aircon system is actually not as low as we think. My office is >55%. I personally have seen lenses stored in funan growing fungus, but I am not talking about camera shops though, just camera enthuist.

Brand new lens sitting in airconed shops can grow fungus. This is especially true for lens that are not very popular and see very slow stock movement. For instance, when I searching for the sigma 150mm macro, out of the 3 copies that I looked at, 2 were showing signs of early fungus growth. It is only obvious when bright led light is used to view.

Anyone been to MS Color @ AMK? Their shop is situated in an open ground just next to a food court. They do have air con but not as effective as indoor shops.

usually new lenses are wrapped in plastic bags in their respective paper boxes... don't think dust will be an issue though.

Yes unless never regularly clean the surfaces.

Posted are a few shots using my Nikon coolpix4500 to prove what i meant about air-con building producing dusts. Lucky i told my office to get dry cabinets... LOL

What you need is a cleaner not some dry cabinets.

Because fungus spores have to enter the lens to start thriving. In the factories, there is a clean environment whereby the amount of dust and microorganisms in the air are monitored and actively cleared. (I hope so, or only the sensor and processors are manufactured in ultra clean environment?)

Unless you open the package, test the lens in the shop and put it back in, no fungus spores will be introduced to the lens. it will sit in the packaging with no foreign matter intoduced to it.
