Canon - Warm house to cold outdoors

timberrattle

We received 5 inches of fresh snow last night. I'm wanting to take my Canon D7 and new lens outside for some shots but I'm concerned about the camera sweating. How much harm can this cause to the camera and lens? What precautions can I take?

Too much money invested to create problems! Thanks!

No real concerns. Just put the lens on the body and put all of it in a big ziplock bag and head outside. After about 5 - 10 minutes bring the camera out of the bag and snap away!

Basically it creates a vapor barrier while the camera cools down the ambient temperature. This trick works in the summer to.

Thanks bike21! Are there bags made specifically for this or just any big ziplock from a grocery store?

Any old bag will do, I prefer the bags with the slide lock to ensure full barrier protection & closure but I don't think it really matters as long as it is sealed inside.

It is the return from freezing cold to warm indoors that you want to be most careful about. That is when condensation is a huge issue and you should leave your camera in a decently sealed bag for 10-20 minutes at least...

Going out into the cold from a warm indoors is less of an issue.

BTW, if the Canon 6D can handle this, your 7D can handle it too!

works in cold and tropical climates where you have heavy air conditioning inside

Indeed! Was quite handy in El Salvador this fall.
