That works. Honestly though Boris, you are obsessing over very little. The climate I have lived in all my life has a temperature range that reaches from around -40ºC to +40ºC, and I have never had a piece of equipment go down to condensation damage in the entire 35 or so years I have been playing at being a photographer. The most that has happenned to me is that I have been slightly inconvenienced while waiting for a lens to warm up enough that a film of condensation evaporates.

This may be fine advice with the camera, but have to disagree with lenses. The hair dryer is not directly having an effect on the condensation. What it is doing is warming up the glass, plastic and metal that the lens is made of, which in turn evaporates the condensation. Admittedly, the majority of non-professional situations will preclude such drastic action. In my world, it's a seldom used necessity. My video lenses are a business capital expenditures and will be replaced probably about once every three or four years. Turning a hair dryer on them is no worry to em and very effective. If it were my stills camera and lenses, I wouldn't. I'd take bill's advice. -- Cheers, Cotty ___/\__ || (O) | People, Places, Pastiche ||=|http://www.cottysnaps.com _ -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
Re: One more question about condensations
Bill, Bob, I have been given another suggestion. What if I simply keep the camera inside my jacket and take it out to the cold only to take a shot and then immediately shove it back in beneath my jacket... I will probably make a mix of all the suggestions and see how it goes on location.

Condensation on the outside of the equipment should be wiped off, although it can also be fairly safely ignored, since it will correct itself eventually. Moisture inside the equipment can be more problematic, though even that will generally go away on it's own fairly soon after the gear warms back up. This presumes that the gear is only slightly colder than freezing. The colder the gear is, the more care should be taken to ensure it stays dry when taking it into a warm place. Plastic bags are all well and good, but wrapping the gear in a towel or an item of clothing such as a jacket will help keep water from condensing on the equipment. Wrap an oversized scarf around your neck when you go outside, and wrap your camera in it before you go in. That should take care of most any problems you will run in to. Don't bother with hair dryers, all they do is blow dust into your camera, have very little effect on drying the harmless exterior condensation, and absolutely no effect on anything that forms on the inside. I don't think modern electronic cameras are as prone to condensive moisture damage as older mechanical ones, either.

Re: One more question about condensations
Boris, Don't obcess about this, just take some 'Baggies' with you and bag the camera upon entering warm, humid places from the cold. 'Baggies' are a product name here in the US for sandwich bags. They are thin plastic film and come in various sizes. They started in the sandwich bag size to hold 2 slices of bread and sliced meat. They progressed to larger sizes to store leftover food in the refrigerator. Take 4-5 of these thin film bags that are big enough to store the whole K10D. Pop the camera into the bag in warm/wet places and use a rubberband to seal the top. You can hold the camera to hurry the heating up process or just let it sit to reach room temperatures. Take some of the small baggies along for your spare lens. A lens in a baggie in your pocket stays warm and doesn't pickup any pocket dust. You can wipe condensation off the camera body and front of the lens - easy to do. You say 'awe shit' when you look thru the viewfinder and see it on the mirror and back of the lens. You can wipe these off too, but this is less desirable. You hope to never see it on internal elements of your lens as this takes time to clear. >From a scientific basis, most buildings have trouble maintaining a high level of humidity in minus 25 degree C temperatures. The inside of the windows and sometimes even the walls sweat...becoming covered with moisture. The inside air is cleared of water vapor as it is precipatated onto the cold exterior walls/windows. This can make the windows frosty and indoor environment very dry and desert like in winter. Overall, count on the K10D'sweather sealing to help you thru this... Regards, Bob S.

Re: One more question about condensations
I've had condensation form in the viewfinder window, which is a bit of a nuisance. Like Paul, I've not had any form inside a lens, but that may be because I haven't "exercised" the lens (which would draw moist air inside it) until it has warmed up. I've done lots of winter shooting in which the camera got =well= chilled (3 hours shooting ski races, for example), and have never had a serious condensation problem, even with cameras (like the (P)Z1-P whose bodies aren't the least bit sealed.

Re: One more question about condensations
I've experienced condensation many times in the summer when going out from a cool, dry air conditioned house into the hot, humid backyard. Condensation forms on the front lens element. I don't know if I get any inside. I never wipe it. I just let it sit until it clears up. It usually only takes about five minutes. Once it took twenty minutes. Never caused any problem and left no residue on the lens. It's distilled water after all. It should be quite clean. I've never seen any condensation on the camera to speak of. If there was any, it didn't affect it. That's true of both the K10 and the D.
