Thanks for your question and the sample photo of mist forming on your lens. It's a common problem for warm moist air to condense when it comes in contact with a colder object.
It's an issue that I run into occasionally when I shoot sports teams early in the morning when there is a lot of moisture in the air. You can also get a misty lens when you live in a cold climate and have a long photo shoot outdoors, or leave your camera gear in the car overnight and bringing it indoors. Bringing your camera unprotected into the warmer environment of a heated building will also cause mosture to form on your lens and camera.
Either way it's a situation you want to avoid, because you could have moisture forming on the inside of your camera and inside your lens. That could be damaging for both.
how to prevent Blur From a misted lens
You can't change your climate, but you can sometimes try to shoot when the weather is cooler or dryer. That is often not possible, but there may be some times when this will help enough.
It's more likely useful if you can store your camera in your automobile's trunk while you are driving. That way it will already be the same temperature as the outdoor air and will avoid the misty lens problem.
Alternatively, you can just allow more time and arrive at your photo destination early and allow your camera to warm up before you take it out of its case and expose it to the hot humid air.
This could vary between 15 minutes to an hour, depending on all of the temperatures involved as well as the camera case thickness and style.
A small amount of mist on just the lens or the outside surface of your camera can easily be wiped off with a lens cloth.
Good luck, Leilani, and thanks again for your question.
