Have you filmed or photographed a wedding during the Covid pandemic? If so, I’m willing to bet that you encountered your camera’s viewfinder fogging up throughout the day.
Am I right? Why? Due to wearing your face mask of course.
OK, so wearing the mask is important for obvious reasons. But surely it is possible to wear the mask without it fogging up the camera. Life as a wedding vendor is already challenging enough as it is!
As a wedding videographer, this annoyance happened to me during the first wedding I filmed since restrictions eased to allow weddings to proceed.
In the middle of the shoot, the viewfinder fogged up so bad that I couldn’t see anything through it. Then it happened later when I was covering the couple’s sparkler wedding send off exit in the evening.
It was stressful at the time because I felt I would miss important shots unless I came up with a quick solution.
Thankfully, I did come up with an answer and I’ll share this below along with other anti-camera viewfinder fogging up tips that I’ve learned since.
A camera’s viewfinder can be protected against fogging up by replacing the standard oval eyepiece with a larger rubber eyecup. The replacement rubber eyecup forms a tight seal between the viewfinder and the person’s eye socket. Warm air escaping from the top of the face mask will be prevented from entering the viewfinder and causing condensation to form.
How To Fix the Camera Viewfinder Fogging Up While Wearing a Mask Issue
Returning back to the story of the first wedding I was filming while wearing a face mask. When I experienced the viewfinder fogging up problem, I remembered that I had a backup rubber eyecup in my camera bag.
The eyepiece that was attached to the camera at the time was the standard one that came supplied with my Sony camera. So I decided to swap it out with this Eyecup Eyepiece (affiliate link) that I had purchased from Amazon. It worked a treat!
This eyecup below makes it much easier for glasses wearers to use viewfinders.
What types of Eyecups for Sony, Canon, and Nikon cameras prevent the viewfinders from fogging up?
A quick look on Amazon reveals that the following models can be obtained. I own the one for the Sony A7III and it works really well. No more fogging problems when I wear my face mask!

Alternative solutions to the camera viewfinder fogging up from wearing a mask problem
Apart from holding your breath all day, there are other options for helping deal with a problematic camera viewfinder fogging up situation.
There are various commercial anti-fog lens cleaning wipes available that will help.
Some people have also reported that if you get a small bit of ordinary soap and rinse it into a lather and gently wipe that onto the viewfinder surface. It will leave a tiny layer of invisible protection on the viewfinder that should prevent it from fogging up when you really need to see through it.
Another tip to prevent the viewfinder fogging up is to twist the straps of the facemask so that it is tighter on the face and slows down the amount of air leakage.
What about trying alternative masks? This could also help to alleviate any condensation from forming on the viewfinder due to warm exhaled air leaking from the mask as you breathe out. We all have to breathe, right?!
Try using masks that have a thin strip of metal that runs along the top edge. These strips can be manipulated to fold around your nose to make them more comfortable and sit tighter on your face to reduce the amount of warm airflow.
Allowing your camera to acclimatize is another suggestion. So, if the camera has just come from a cold bag in the trunk of the car, let it warm up first in the air for a few minutes before you start shooting.
The idea is to minimize the difference in air temperature between the environment the camera body came from and the temperature of the air in the new environment.
This next suggestion doesn’t look great but it reportedly does work! If you take a thin piece of tissue and fold it along the edge of the mask. It will absorb the moisture from your breath as it passes over it.
If you wear glasses, it’s ideal if you can wear your glasses over your mask to prevent them from fogging.
Wearing the right face mask is important to blend into the background just like the advice we give about what to wear as a wedding photographer or videographer.
And there you have it. Plenty of practical suggestions to help with the problem of your viewfinder fogging up when wearing a mask due to the Covid pandemic.
