Default shooting in winter

Manual for canon A70 says operating temp 0-40C (32-104F). Does it mean I won't be able to shoot in winter when it's below 0? And if I keep camera under jacket and it's warm can I use it?

JED, I used my S30 at 20 below already. It performed fine and the pictures came out wonderful. I did just what you said, I kept it in my inside coat pocket. I would imagine the temperature range the manual states is optimal shooting temps.

My biggest concern would be about condensation...

Anyone who wears glasses will be familiar with this - if your camera cools down significantly when you're using it (outside your jacket), and then you put it back under the jacket where it's warm and relatively humid... you're going to get a lot of condensation on the lens and possibly inside the camera body.

If you have it out for a significant amount of time (long enough to get very cold to the touch), I would not put it back inside. I think you would risk more damage by warming it too quickly in a humid environment than by just leaving it out where it's cold.

On the other hand... it occurs to me that it does get quite warm to the touch when it's turned on. As long as you don't carry it around in the cold turned off (ie, keep it on while it's out of your pocket), the innards shouldn't get cold enough to induce condensation.

I'm just speculating, anyone have a more informed opinion?

Default Avoid Condensation Related Problems

A80 manual, page 13:

"Avoid Condensation Related Problems

Moving the equipment rapidly between hot and cold temperatures may cause condensation (water droplets) to form on its external and internal surfaces.

You can avoid this by placing the equipment in an airtight, resealable plastic bag and letting it adjust to temperatures changes slowly before removing it from the bag."

Sometimes it is a good idea to read your manual....

Thanks for replies, I know about condensation, I've read about this in manual. But if I keep it all the time outside where it's cold is it going to work? I don't mean -20, rather -5 or so. I know tha all electronic don't like cold but where's real point when it stops working? Anyone knows?

Default Cold Camera

It seldom gets below +20 F where I live in Washinton State, USA I have read that the batteries will drain or just stop working and the LCD slows down along with the condensation issue. Someone said that everything slows down.

As long as you keep it your inside jacket pocket when you are not shooting you should not have too much trouble as long as you extra batteries.

A search for "temperature" (without the quotes) at http://www.dpreview.com/forums/forum.asp?forum=1010 lists these posts (there are more posts there too) for different Canon cameras but it should be the same for all models.
