Dew heater nice - but... - Forums

Hello!

Newbie here - I'm about to start using a dew heater for the first time. Well and good, but what about my DLSR? I've got both a Canon 90D and Canon 6DMkII. Both are "weather resistant" with the 6D perhaps a bit tougher, but a couple of hours with dew on your camera body?

Thoughts?

Hi Mike,

Based on my experience: no problem. My DSLR survived dew and ice (first dew, then temperature drop, then ice).
For the DSLR holds the same as for all the other equipment: after use, make sure the dew can evaporate. My stuff is mobile and so when I bring everything inside, I place it on the table and all openings open (dust-protected of course). After a few hours, all dew will be gone and then it could be stowed away.

Cheers,
Björn

I don't think you need to worry about dew on the body of the camera. The sensor is not exposed to the atmosphere once the lens (or scope) is attached. So as long as you have a dew heater on the lens or scope objective (which are exposed to the atmosphere) you should be fine. That's what I do anyway and I've never had a problem.

Hi Mike,

I can only agree with what has already been said, no problem. I have used my Sony Alpha in sessions with -10 Celsius and with heavy dew and it never failed me.
The only aspect you should pay attention to is to use a proper power supply for the camera. A battery is dying pretty fast in low temperatures.

Thanks all! I guess I was concerned because a few years ago, I had issues with corrosion caused by exposure to rain. I think that was a 70D, but still - the problem didn't show up the next day, it took some time before the arrow keys started to fail.
