@fotoworx; what do you do when you take the gear out of the dry cabinet & actually use it?
It's still going to be used in humid environments

Since they are in a dry cabinet, would it make more sense to remove the caps so that the equipment gets "Dried" out sorta speaking?

The dry cabi is useful for countries that are perpetually humid. It simply stop the fungus from growing if left in the open for a long period of time. Once u get them out to use, you will be moving around and less likely to leave it stationary for a long period of inactivity. If you stay in a country like mine and put all your stuffs outside for long period, either you are thinking of switching your system to Nikon or giving up photography for good.

I'm not sure Nikons would fair any better to humid induced fungus growth...

I jsut don't see the point, same with those silica-gel packets, once exposed to air, it's all moot.
Just because your moving around doesn't mean humidity won't affect it.

When you move around in a humid environment or you stand still, you're body still perspires so keeping your gear in a dry-cabinet then using outdoors won't make difference to the life of the gear.

do not entirely agree.

i agree that just because you are moving around that does not protect you from the humidity. however. a dry cabinet, although will not completely eliminate the exposure to the humidity, will certainly reduce it.

Sun light kills fungus, a dry cabinet will stop its growth during non-use.

A dry cabinet makes perfect sense in any humid climat, my question was whether it was more effective without the lenscap/bodycap/uvfilt​ers seals by allowing the lens to reach the dryer humidities faster.

The thought of storing gear in a wine or cigar type cabinet seems ridiculous, until you consider that fungus thrives on continued exposure to moisture and heat. If I had those thousands of dollars worth of equipment in that kind of environment, I'd absolutely want to have humidity and temperature controlled storage, even if I was using some of the equipment every day.


Replacing my Canon 7D, Tokina 12-24mm, Canon 17-55mm, Sigma 30mm f/1.4, 85mm f/1.4, and 150-500mm with a Panasonic Lumix FZ1000. I still have the 17-55 and the 30 available for sale.

Nothing, you use it as normal then pop it back into the dry cabinet afterwards.

Fungus takes time to grow. Its not going to grow as soon as you take it out and it gets exposed to humidity. It will grow if the lens is exposed to the correct conditions (humidity, heat) for a period of time. Using a dry cabinet or silica gel packs means that after you finish using the equipment (which is a very short period of time, speaking relatively), you return the lens to an environment which is inhospitable to fungus, meaning it will not have a chance to grow at all whilst waiting for your next use (which may be a very long period of time).

Saying a dry cabinet or silica gel packs are useless or don't make sense just shows you don't live in a very hot/humid place and don't know what can happen to camera gear in those environments.

As regards the moving around etc... it does make a difference: fungus spores need time (yes, again its down to time) to grow. Using a lens means that you are constantly changing its internal volume (focus, zoom) which sucks/expels air and dust, and fungal spores. If the spores are being blown around, they are not going to grow. This is pretty well exemplified by the saying "a rolling stone gathers no moss" although moss and fungus aren't exactly identical, the idea is the same.

As for storing the lens with the caps off, I don't really see the point. The caps aren't airtight, so the dehumidifier will have no trouble extracting the moisture.

Dry cabinets in humid areas (and there are plenty of humid areas and fungus infected lenses in the U.S ) make perfect sense.

One of the first questions a buyer will usually ask of a seller selling a lens is "Any fungus in the lens" ?

Carbon Fiber Lens Hood

The smooth tracking and strength of a heavy metal hood with the lightweight high-performance responsiveness of a hood made from hummingbird wings.
