Appmax Posted March 27, 2013 Share #1 Posted March 27, 2013 Advertisement (gone after registration) Is there a risk of internal condensation forming/staining lenses as a result of thermoclimb? For example, if I keep my camera in a cold car and then warm it up by bringing it into my house, do I run the risk of condensation forming in the lens? How about if it is out in the sun after being in an air conditioned hotel room. I have never heard of this happening but don't want to risk staining the internal working of my lenses.

jaapv Posted March 27, 2013 Share #2 Posted March 27, 2013 There may well be condensation under adverse circumstances inside a lens but as condensed water is 100% pure there will be no staining, normally. Quote Link to post Share on other sites More sharing options...
tobey bilek Posted March 27, 2013 Share #3 Posted March 27, 2013 I wrap my whole bag in a parka or quilted blanket. Warm up is 8 hours. Water will react with the crud already inside the lens whether you know it is there or not, it is there. Sensors curd up in a similar way from my repairman.

Appmax Posted March 28, 2013 Author Share #4 Posted March 28, 2013 I have always taken my lenses in with me to ovoid excess heat or cold. It just seemed like the right thing to do. Sounds like it is a good practice so I will continue. Thank you. Quote Link to post Share on other sites More sharing options...
250swb Posted March 28, 2013 Share #5 Posted March 28, 2013 How long have Leica been making rangefinder cameras? How long has this been a problem? The answers are forever and never, in that order. Yes your camera and lens can steam up inside, but it dissipates. The time it becomes a problem is if it happens while you are shooting, perhaps by trying to keep a cold wet camera under a warm dry coat. But there is water in your camera all the time, it is in the air around you, common sense is all that is required, no special measures. If you get condensation inside put your camera or lens near a radiator. Steve Quote Link to post Share on other sites More sharing options...
jaapv Posted March 28, 2013 Share #6 Posted March 28, 2013 I just take a hairdryer to the camera. Works like a treat. It is not just the lens that fogs up, the viewfinder is even more prone. A real PITA when in a rainforest....(no hairdryers there...) Quote Link to post Share on other sites More sharing options...
tobey bilek Posted March 29, 2013 Share #7 Posted March 29, 2013 Advertisement (gone after registration) So you read all the abuse and see what people do. I prefer the safe route above. Been doin it that way 50 years. Quote Link to post Share on other sites More sharing options...

250swb Posted March 30, 2013 Share #9 Posted March 30, 2013 I wrap my whole bag in a parka or quilted blanket. Warm up is 8 hours. And don't forget to cool it down for 8 hours before going from hot to cold. Timing is everything to catch half an hour of shooting on a winters day, but I find with 16 hours warming up and cooling down one roll of 36 exposures lasts all winter so safe is also cheap!

swamiji Posted March 31, 2013 Share #10 Posted March 31, 2013 (edited) Cameras, Like people, need fresh air and sunshine. If you are concerned about fungus, when you take a break from shooting, and relax with a beverage of your choice, just put your camera (with all due caution) in the sun. Best cure for fungus. It's storing your lenses/cameras in high humidity for long periods of time that is the issue (even in your bag). Fog happens, it passes. A hair dryer or blanket, just alters the timeline. My take, don't worry about it. Unless the shot is 6 feet from your hotel room, the fog most likely will have passed by the time you need it. I have gone down to Yunnan, to the burmese border. Taken part in the spring water festival. I just covered my camera when being attacked by pretty girls squirting water at me... No problems, just put my camera on the dashboard of the car on the return trip to the hotel. When I got back everything was dry.
