I live in South Dakota. So, I can go from 75°F (24°C) with moderate humidity (indoors) to 0°F (-18°C) and dry just by stepping outside. Can this damage my lenses?

I especially want to know about damage to its optical performance, due to crazing or changes in alignment, or whatever else - such as condensation leading to fungus. So, this includes damage to the lens coating. But I'm also curious about other damage. For example, if it shifts the housing clearance and allows more dust to get in, which could impact the image quality.

And if it can cause damage, then what parameters should I stay within to prevent damage (duration of exposure, temperature, humidity, etc.)? And does it make a difference if the lens housing is plastic or metal?
