I think I would opt for 2-20 rather than 1-10. Can you say jailbait????
;-)

But I read it on the Internet! It must be true. :D

:thumbup:

I reckon you've nailed it Ore-D
Hot humid places are worse for camera equipment
moisturewise than very cold places by a long chalk.

Water vapour (humidity) in hot air will readily condense
on a cold lens, in fact there are places where water could
literally be running off a cold object like a camera taken out of
a cool air conditioned place (or a beer can taken out
of the fridge)
and into a hot humid environment.

Dry air is your gears friend.

I reckon (correct me if I'm wrong) in very cold climates air is dry as much water vapour may be frozen out of the air. Those of you with snow on the roof who have rushed off to the weather page to check your humidity, dont confuse "relative'' humidity with the amount of water vapour in the air.

So if the air is dry in your warm home removing the lens
caps to "thaw" your equipment would not hurt.

If your heating system is heating cold air drawn from
outside, drying the air further it, I reckon it would be a
great idea to remove the caps from a lens to "thaw it".

Would anyone reading this like to explain the difference
between humidity and relative humidity?

Very dry air can be a problem for humans so some space heaters have a facility for "humidifying". Perhaps MTs home or studio has one of these, or a steamy laundry or something else that is creating humidity inside when it is below
freezing outside... MT?

Anyone who is interested in considering the plastic bag solution needs to be aware that they must squeeze as much of the air as possible out of that bag when sealing it outside so as to minimize the possibility of condensation forming inside the bag as well as that air warms up faster than the metal or plastic camera components.

Now there's an idea for a new photo accessory: a portable, battery-powered vacuum pump that will work with plastic bags of various sizes. You sell the starter kit and continue to sell replacement bags of different sizes. It would be good for longterm storage of your equipment inside the house, too. There are lots of possibilities for names: Air Sucker, VacuCam, Suck It Out, or, for the improved model - SuxMor.

Lets see, he is advising to bring frozen lenses into a warm, moist atmosphere and take off both caps?
Under NO circumstances would I do this as that actually will promote condensation to form on ALL your cold surfaces. That cold air is INSIDE your lens as well, and that's the last place I want condensation to form.
Thanks, but that's one tip I will NOT be following, or passing on to anyone. I would rather have my lenses last a bit longer, especially the newer ones with circuitry and motors inside them.
