How to stop your lenses from fogging up and why you need to

Aug 4, 2017 by John Aldred 3 Comments

Lenses fogging up usually isn’t a big problem for me here in the UK. But it is a problem I’ve faced while shooting in warmer climates. You go from a nice cool air conditioned building to the hot and humid outdoors and there it goes. Within 10 seconds, your lens is virtually impossible to see through.

If your lens is weather sealed, it’s just a waiting game for it to clear up. If it’s not, you can face long term consequences. This two minute tips video from David Bergman offers several ways to prevent fog on your lenses when you change environments.

Clever Lens Heating Tip For Star Photography

Shooting the night skies is a very rewarding field of photography, especially after you’ve sat in the dark cold night for 5 hours waiting for a time lapse or a startrails sequence to complete. But if you are shooting in a cold location (or a terribly cold night) you may lose the sequence to dew or condensation.

Once the camera hits the same temperature as the ambient temperature, some mist (or worse, dew) can start building up on the lens. If you are lucky it builds on the outside of the lens, creating a fuzzy blur to the photos. If you are unlucky, it can create drops of water inside the lens.
