Where do you store your lenses?

I've just received a dry cabinet, and it's in process of setting the humidity to desired level.

Once the level is reached, I plan on keeping the camera, and lenses inside (no wonder, right?) What concerns me is each time I'll reach for the camera or another lens, the air from outside will enter the cabinet, and the humidity will rise again. The cabinet needs some time to reduce the humidity. If I use the camera on daily basis, the humidity in the cabinet will always be different than desired, so what's the point?

 

Should I put something like Silica get into the dry cabinet, or something else to speed up the process of getting the humidity level back to let's say 40%?

I store my lenses wherever they will be easily retrieved. Do you all really believe your lenses will become corrupted within your lifetime due to environmental conditions, and if they will, then how long will it take?

Pico,

don't you not worry about possible focus shift in fast lenses ( at f0.95) due air density and consequently the refraction index change of extremely dry air being trapped between lens groups and elements amounting perhaps as much of a shift of the perfect focus from eyelash tip to the root of the eyelash ?

Perhaps it is compensated for in all inner workings of the rangefinder optics.

I quit using fast lenses in dark public places when I found I was sucking light out of the place, blinding people.

 

One time my fast lens sucked out all the scarce ambient light and I had to use my flash, over and over, to find my way out. A hippie thanked me.

you could worry yourself to death with such 'possibilities'

 

reminds of a saying taught me by a hungarian a long while ago

'Ach, he hears the grass growing'

I recently scanned a few negatives from the Summilux 35mm of the Seventies and found back focus at six foot focus. Ya know, I could not care less. A good photo survives nonetheless.

I don't think you need to worry about the time it takes for the humidity to get back to 40% RH, unless it takes several hours. I do open my dry cabinet almost on a daily basis and it takes less than an hour for the RH to reach 40% RH. In Singapore, the average RH is over 80% everyday. The first time when you start using the dry cabinet with your cameras, lenses, etc, it will take several hours to reach the 40% set-point. Depending on how long you keep the door open and the amount of moist air getting into the cabinet, it will only take less than an hour to reach 40% again.
