But, those who know about it do admit that there can be nothing quite as annoying as discovering the fact that your favorite lens has become a breeding spot for the fungus. But then, it still seems quite impossible to believe that something could actually grow inside the lens. Most of the people passionate about photography, prefer to clean their lens on their own. Depending on the climate of where you stay, the lens fungus could actually be a huge issue and therefore it is best to familiarize yourself with it. 

Why Does Fungus Form In Lenses

People often as to why does fungus form in the lenses. Well, it happens when moisture gets trapped on the surface or the inside of the camera lenses; it combines with warmth and can lead to the growth of the fungus. If you have ever seen the growth of the fungus in the lenses, you would notice that it looks almost like a tiny spider web.

During the early summer or spring, when it pours frequently, there is a lot of moisture present in the air. This is the time when you as a photographer need to take care of lenses properly or soon you would be able to native the growth of fungus in it. Also, having the right lenses for a Beginner’s Photography kit is very essential.

And keep in mind the fact that it doesn’t depend on the build-quality, brand or price of the lenses. Wherever there is moisture, there would be the growth of microorganisms. The fungus present inside your lenses can actually eat away its coating or lead to optical aberrations. In cases of new lenses, it could even erode the glue which keeps all the components in its place.

3. JIS Screwdriver Set 

You would need this screwdriver set for the lenses that are made in Japan. They look quite similar to that of the Philips head/cross-tip screwdriver but are different. You need these for the Japan made lenses or else you would end up damaging the lens rather than getting rid of the fungus. However, if your camera lens aren’t from Japan, then Philips head screw drivers are good to go!

4. Tweezers

Any kind of tweezers would work just fine, this will help in extracting the fungi easily

5. Soaking Dish 

A ceramic dish or bowl would be good 

6. Parts Dish

7. Safety Glasses

You aren’t performing a lab experiment but then protecting your eyes from any kind of chemicals is extremely important

8. Nitrile Gloves

The fungus-killing solution that you are about to make can actually dry up your hands. The gloves would protect your hands and would also keep the lens dry and clean when you are working on it. 

9. Ammonia (home purpose) 

You can easily find this at your local home goods store. You can find scented and unscented ammonia. Try and get the unscented one if possible. Otherwise, it doesn’t really matter what kind you are using. 

10. Hydrogen Peroxide 

You can get it easily from your local pharmacy. 

11. Microfiber Lens Cloth 

This cloth that you are going to be using for the lens fungus needs to be absolutely dry and clean. It is best to avoid using the one that you have been carrying in your camera bag or your pocket for long. Any kind of oil or dust present on the cloth can get into the internal surface of the lenses and you would never be able to get that spotless finish that you desire. Have at least two extra microfiber cloth stored in a zipper plastic bag that you do not do not use often. Or, keep replacing the one that you use. For this process, make sure that you are using a new one.

Words of Wisdom- How to Get Rid of It?

Now that you have gathered all your tools, it’s time to move on to cleaning the lenses. First, you would need to take your screwdriver and remove all the screws that hold the lens mount. Once you do so, you would slowly be able to get rid of all the components that hold the lens down. 

To remove the glass, there are several ways that it can be done. You would need to tip the lens upside down in your hand. Most of the times, it would easily come off. In case, it doesn’t, you would need to reinstall the retainer ring part-way and use a blunt object that isn’t made up of metal to rap the side of it gently. You should tap it only for a bit in order to encourage some movement. 

The first piece of glass that you take out would have some traces of fungus. The other glass is what would have the most of it. Now that you have your glass in your hand, let’s get to work. Mix equal parts of ammonia and hydrogen peroxide and stir it well. Ensure that you are working in an area that is ventilated. Place a lens wipe on the bottom the dish so as to protect the lens from getting scratched while it is being soaked. 

Place your lens in the solution and let it soak for 2 minutes. Most of the fungus would be washed off the rest you can use a cotton ball and clean it up. You might need to soak it longer if there’s too much fungus. Use the lens poofer to wipe all the droplets and with the microfiber cloth wipe it gently. Clean the remaining elements too and put everything back together. 

You could also shine germicidal UV (ultraviolet) light into the lens for a long time so as to discourage the growth of lens fungus. You could also consider leaving the lens with the iris open on a windowsill that gets enough sunlight. This might also work. The best solution is to never let fungus invade your lenses. Lenses are pretty expensive and therefore it is important to take proper care of them.
