Hello friends,
recently I just got back from a trip... it was cold and rainy whilst I was there, and to make matters worse - I was staying in a hotel room with an Aircon control that was broken (and unable to turn down the freezing cold temperatures... ok budget la, no choice).
So what happened was in morning that I happily took my DSLR out to shoot breakfast scenes... to my horror I found that...
THERE WAS CONDENSATION ON THE LENS(ES AND MAYBE EVEN WITHIN THE REAR ELEMENT!!!)
And wiping it away with the micro-fiber cloth didn't help since it just came back again.
So my question:
- any useful tips to 'prevent' condensation happening?
- in the event condensation does happen, how to deal with it?
- is it safe to use those 'anti-fog' sprays for spectacles on the lenses?

Planning to go Europe in winter sometime - need to get educated on the perils of condensation before embarking on the trip.
Thanks!!!

If you're not on the move, you can put your camera in an air tight ziploc bag before moving from a cold place to a warm place, and let the temperature equalize before taking it out.

- in the event condensation does happen, how to deal with it?
Just leave it, the fogging will be gone once the temprature equalizes.

- is it safe to use those 'anti-fog' sprays for spectacles on the lenses?
No! It will damage your lens' coating.

Btw, we have a sticky that you might want to look at, here. Cheers and enjoy your holiday. :)

No need to worry one. And yes, leave the lens alone, stay away from whatever spray you may wanna use.

Ok, I was faced with this situation for sometime where the BBQ is outside (well obviously :D) but the party was inside a very very cold air condition room. So whenever i moved out to the BBQ area, the lens would fog up.

I had to take shots pretty quick and couldn't wait for the temperature to sync so I just used the blower on the lens to speed up the temperature alignment. Beats waiting long times.

Wonder if this hurts the camera/lens in any way?

Thanks - very useful info too... batteries sound like the most important accessories then!

BTW - anyone knows where to get a rain/snow jacket for my FastPack? (Well it's water-resistant but not waterproof I believe...)
Better to be safe than sorry!
