This is why you need a dew lens heater.  One of the more annoying aspects of night sky, early morning and cold weather photography is dealing with dew. Particularly in moist climates on a cold night or morning, moisture in the air condenses onto the  front surface of your lens rather quickly. This can bring a photography session to a rapid end and can rule out long exposures or time lapse sequences.

A dew heater or Lens heater is a must and certainly a cheap way to improve your photography cheaply and very effectively especially while travelling.

I have been given the chance to test a Dew heater unit from Decolighting and I am amazed just how good it works.

For a dew heater to only cost about $20 is pretty amazing so I had pretty low expectations, but they were soon gone once i hooked it up to a power bank and had my lens warmed extremely quick and kept it dew free while out in the cold Brisbane morning.

The service from Decolighting is second to none and came in the mail oddly, quicker than sending a local envelope.   This is a must have for any avid photographer and I know for a fact I will be keeping one in my caravan for future trips.

The best thing about the heater is it’s versatility.  The power port is USB giving you a huge range of ways to power it. The quality is up there with any name brand giving me confidence that I will get the shot I want when I want it.   If that’s not enough it can be used for other equipment like telescopes and is compatible with nearly any DSLR lens on the market and can even keep your soup warm!
