Lens fogging up

[Magnum]

I am wanting to take some pictures of my grand kids tonight.

My lens is fogging up, maybe because I am close to the ocean.

Thanks.

The likely problem is that the temperature of the lens is below the dew point of the surrounding air, so you should be able to solve the problem by (gently) increasing the temperature of the lens.

Hi,

   Michael's solution is probably the best idea.  However, if for
whatever reason it does not work, then you can (carefully) put
plastic wrap across the front of the lens.  That assumes that
the lens is suitably recessed.

Cheers,

I'm guessing that you're moving from inside to outside, or outside to inside, and the lens is fogging shortly after.

Moving from inside (warm) to outside (cold) will cause the lens to become colder than the (warm, indoor) air temporarily trapped within the lens structure (there will be multiple lenses), and thus moisture from the warmer air will condense on the colder lens surfaces.
Moving from outside to inside will have a similar effect, but on the external surfaces instead.

In either case, leave the camera to sit in its new environment for a while (20 minutes) to allow the internal temperature to match the external. The moisture should clear itself.
