    Keep the lens or camera in camera bag with zip opened for about 1/2hour (depend on how cold is inside, and dryness or humid is outside) before use outdoor.

    You must put your lens in an airtight plastic bag or any airtight container then wait until the temperature of the lens matches that of the outside temperature before using it.

    only possible if u carry along a thermomether to measure the temperature of the lens and the surroundings.

    best practical solution is to just take out the lens and wait for around a few minutes or more before using it.

    It doesn't work. Silica gel is not to maintain temperature. It is to maintain humidity to prevent/slowing down fungus growth. No, I mean closed box humidity, not outside environment humidity.

    Yes, another way is to "warm up" your equipment if you are expecting to go from air-con environment to outside. If you have the time and know beforehand, can try to put your equipment near those industrial aircon warm-air outlet (or other moderate heat source) for a while till it warms up (feels warm to touch), then when you bring outside, your equipment temp and outside temp should be about the same and the water vapour won't condense liao.
