Post Lens Fog
Hey guys!
I need a practical source for keeping my lens from fogging over during night shoots. I saw some older threads discussing it, but wondered if there were any newer techniques/technology.

The fog wipes... Are these toxic?

Hand warmers, I live in FL and have never come into contact with these... Are they something you use once and then toss out?

Dew heaters... Are there battery operated ones?

What's most user friendly?

Thank you!

I don't understand why you need to know if those fog wipes are toxic and I don't even know the answer, but don't eat them.
I have however used them on my lenses and they seemed to work, but i still don't 100% trust them

Hand warmers are my go to... Since you can't seem to find them in your area, I'd order a Pack of handwamers from amazon
What I do is take a sock and cut the end off, then put a rubber band around it and them put a rain jacket around the entire camera and lens barrel to help isolate that heat to that area.
Might be overkill, but it has never failed me.

Dew Heaters seem to be a good option, but they are pricey and its just another battery to possibly forget to pack or charge.

It`s usually the dew controller device which is expensive not the lens wrap itself.
I bought this: http://www.ebay.com/itm/Dew-Not-Dew-Heater-for-3-Telescope-13-Length-DN004-/111148224104?
and with a little modification to the cable plug it straight into a 12 volt battery, omitting the dew controller part. You could even use a split cable and run it off the same battery you`re powering the moco gear with.

im not really sure I would trust that, plugging it directly to 12v sounds like it might get too hot since your not in control of the output what so ever

that could be a factor in a warmer clime than I`m using mine in, but with alpine cold I`m glad for all the heat I can get to the lens. No damage so far.

Haha, I guess I should have been way more specific. Toxic wasn't the right word, at all. What I should have said was... will they affect the quality of the equipment they're used on over time?

Nikon Fog wipes. I would be willing to bet there is absolutely no fear or risk of damaging your equipment.

Just be sure to get the "Non Harsh Abrasive Version"

Any thoughts on this set up?

Also, how do you determine what size strip you would use?

I have bought, set up, but still have yet to use a bunch of dew heater things.

The heater strips are pretty cheap, and so are the lithium batts.
Then the only thing you need to buy are potentiometers to control the heat.
I also bought these on eBay for super cheap, connected DC plugs and off you go.

Search for 12v Dimmer

http://www.ebay.com/itm/LED-Switch-Dimm ... Swo6lWKENe

Works and is cheap. I have no tested the setup to see if it actually works overnight or how long the batteries last for.
I think someone else posted about this, which is where I sourced the parts from.
