How to Keep Your Camera Lens from Fogging Up

Speaking from personal experience as a photographer since I was 14 years old — yeah, I’m that old — I started with a little 110 film camera. Can’t remember the brand, but that’s what started it all. People always told me how good my pictures looked, and that kept me shooting.

These days, I’m using a Nikon DSLR D5300 — a bit more advanced, but I still feel like a rookie sometimes. Over the years, I’ve picked up a few solid tricks to keep your camera lens from fogging up, especially in Florida’s humid mornings.

How to Prevent Camera Lens from Fogging Up in Humid Conditions

Before I head out, I open my camera bag and leave the flaps open to let the gear breathe. I drive early in the cool Florida mornings with the windows down. The A/C runs all night in my apartment, so walking out into that sticky air is a recipe for lens fog.

By the time I reach my photo spot — usually 45 minutes to an hour before sunrise — my camera has adjusted to the outside temperature. If the humidity isn’t too heavy, I’m ready to shoot right away.

First thing I do when I park is jump out, grab my camera, and get the lens caps off so it can keep adjusting. I mostly shoot with my 18–55mm kit lens. Before shooting, I shine my phone flashlight into the lens to check for moisture, then wipe it clean with a microfiber screen cloth.

Simple. Cheap. Effective. Mother Nature does most of the work — no fancy anti-fog sprays needed.

What Can You Put on a Camera Lens to Keep It from Fogging Up?

Everyone’s got their own methods, but here are a few real-world techniques that actually work:

• Plastic bag trick: Before going outside, seal your camera in a Ziploc or trash bag. It traps the dry, cool air and prevents condensation as your gear warms up.
  

• Slow acclimation: If you’ve been in air conditioning, give your gear 20–30 minutes to adjust before taking it out.
  

• Silica or desiccant packs: Keep a few in your camera bag to absorb excess moisture. Replace them regularly.
  

• Portable hair dryer: A quick, low-heat burst can clear mild lens fog fast.
  

• Lens hoods and hand warmers: Great for long exposures or early-morning shoots where dew builds up.
  

• Avoid Vaseline and alcohol: They can damage the lens coating and attract dust. Stick to proper cleaning wipes.
  

How to Keep Camera Lens from Fogging Up in the Morning or at Night

Fog can hit anytime — sunrise shoots, evening walks, even night photography. The key is acclimating your camera lens to the outdoor temperature.

If you’re shooting at dawn, leave your gear in the garage or your car overnight so it adjusts slowly. At night, keep your camera covered until it’s ready to shoot. The slower the temperature changes, the less chance of fogging.

You can also use a small fan or heating strip to move air gently around your lens during long night exposures — it helps keep moisture from settling on the glass.

Why Is My Camera Lens Protector Fogging Up?

It’s all about temperature and humidity. When your lens goes from a cool, dry area (like an A/C room or vehicle) into hot, moist air, the surface cools down and moisture condenses.

Larger lenses take longer to equalize, so if possible, store your camera in a transitional space — like a covered porch or car trunk — for a few minutes before stepping into the open air.

This simple step can make all the difference between a clear shot and a fogged mess.

Can You Use 70% Alcohol to Clean a Camera Lens?

Short answer: don’t.
While alcohol might seem like an easy fix, it can damage the lens coating over time and leave streaks that make fogging worse.

Instead, use lens-safe wipes or microfiber cloths made specifically for optics. Keep a small pack in your camera bag — they’re cheap, effective, and safe for repeated use.

Quick Summary: How to Stop Lenses from Fogging Up

To prevent your camera lens from fogging up:

• Keep your gear covered and protected in a bag.
  

• Let your camera acclimate to the outdoor temperature.
  

• Use silica packs or desiccants in your camera bag.
  

• Avoid home remedies like Vaseline or alcohol.
  

• Be patient — a few minutes of waiting beats fogged shots.
  

Thoughts on Preventing Camera Lens Fog

Fogged-up lenses can ruin a perfect sunrise or golden-hour photo, but they don’t have to. Over the years, I’ve learned to work with Florida’s humidity instead of fighting it.

Open your bag early, give your gear time to adjust, and skip the expensive anti-fog gimmicks. A little patience and preparation go a long way. Check out our Store and browse our selection of Gulf Cost Prints.
