How do I clean fungus formed in camera lens?
If you are feeling brave then it can be cleaned relatively easily as long as the fungus is only on the front or rear element and those elements can be removed without completely disassembling the lens. Often, the front ring can be unscrewed with a rubber cup to give you access to a the ring holding the front element in place. You'll need a lens spanner to unscrew this. The rear element can often be removed in the same way without taking the rest of the lens apart. If you can get those elements out, then gently clean them in hydrogen peroxide and give the inside of the lens a good blow out to get rid of any remaining spores.Sometimes you can kill the fungus by shining a UV lamp into the lens but thus can take days and won't remove the fungus that's already there, it just stops it from spreading.If you're not sure then pay a professional and be prepared for a hefty bill.
My lens got a very tiny fungus, too small to justify a lens clean, what should I do to stop it from growing?
While it depends on the type of lens and previous storage conditions, it almost certainly has spores diffusely, especially if on the interior surface. While not your question, rather than doing something minimal now, it would be better to get a cleaning rather than risk having to do something more dramatic later (since often times it takes a low pH solution to clean these things, which can affect your coating). Best of luck.
I got fungus on my Canon 50-250 lens. Is there any way to clean it without opening?
Warm humid places grow fungus on lenses. I had never seen lens fungus until I moved to Auckland, NZ.The only way to clean it off is to open up the lens; if you have to ask, you can NOT do that yourself. There is a chance that if the fungus has been there for a long time, it may have damaged the surface of the glass.The best way to reduce the chances of fungus is to keep the lens in a dry place. A sealed container with a good desiccant is good. If you can’t manage that, a well ventilated place, like a shelf, in a room that is not a damp-trap will be as good as you can get. The worst storage is in a leather case in a drawer.Exposing the glass to bright sunlight won’t do any harm, and may well stop pores growing.It’s a bummer. I’ve seen good lenses ruined by fungus.
Ideas for how to cure/fix/clean lens fungus and lens haze?
I recently bought a two Olympus OM2n 35mm film cameras off of a lady. She was the original owner since they came out in the 80's. She also had 4 Zuiko lenses that had been stored in their cases in her garage (We live in Florida where humidity is high, causing 2 out of 4 lenses to develop fungus and haze). I bought a few more Zuiko lenses relatively cheap due to having small imperfections such as some slight haze, fungus, scratches, etc. Long story short, I want to try and repair the lenses myself. I did a lot of research but it seems no one has a pin point answer on how to cure lens fungus. I have heard leaving them in the sun will kill fungus. I'm no biologist, but wouldn't putting them in the refrigerator/freezer have the same effect killing fungus? One of my lenses has a small patch of fungus on the inner rear element, so what about taking a magnifying glass in the sun and concentrate it on the patch to kill it? Would that harm any of the glass or coatings on the lens? My cost average on the lenses are $20-$25 a piece, so I really don't feel the need to pay many hundred dollars to send it to a professional. Any ideas would me much appreciated, or feedback on if my ideas seem like they may work. Thanks in advance.
How do you keep your DSLR lens safe from a fungus?
Fungus requires high humidity and suitable temperature to grow on the glass of lens. This knowledge is utilised to prevent fungus attack on lenses. If we store the lens in a airtight container with 40–50%% relative humidity - but not too low (say 30% RH) as the oil in lens may dry up and rubbers in lens may crack - there is little chance that there will be fungus attack on your lens. The dry cabinets come with moisture and temperature control and are routinely used by photographers to store their equipment. They come in different sizes; so can accommodate your small or large collection of lens. Leading brands are DigiCabi, Benro, Sirui etc.[I have no association with the brands of dry cabinets suggested in the text or in the image]If you have a small collection of lenses and don’t want to invest in dry cabinets, I suggest you buy airtight transparent plastic boxes. Place the lens and camera in the airtight box, add some silica gel and keep the whole thing in place where it receives light. It should serve the purpose.
How much would it cost to clean inside of lens?
It will probably cost more than the lens itself. To clean the inside of a lens is a specialist job and best done by the manufacturer. A lens is sealed so if it is getting dirty on the inside then the seals have gone and basically the lens is no good as if it lets dust in then it will let moisture in and this will totally ruin it. 1
How to repair fungus formed lens?
If the fungus is growing on the exterior optics it is likely growing on a coating designed to enhance the optics. The coating might be damaged but you might be able to make the lens serviceable by cleaning with a lens cleaner. If you cannot bring the lens glass back to clear or if the fungus is on internal elements you likely need to have the lens repaired by either the manufacturer or by a competent technician.
I have a Nikon 18—55mm VR lens, and I got fungus inside the lens. I'm planning to disassemble the lens to clean the fungus. But there is some glue (red color) on the screws and I'm wondering what this is? Is it some kind of tamper proof protection?
Looks like a thread locking compound like Locktite (http://www.henkelna.com/industri...)
Camera lens fungus, can thyme help?
Photography is just my hobby, but I have a nice camera and a few nice lenses that I'd like to take good care of. Unfortunately, as a college student, I live in a basement apartment. This can create ideal conditions for fungus to grow in a lens. I was just searching around on the internet, and I came across an idea to prevent fungus. The articles mentioned keeping thyme in the camera bag to help kill fungus because "thymol" in the herb is a natural antifungal. They didn't specify how to keep it though. I'm not sure if it was supposed to be a bundle of fresh leaves, or dry leaves. Fresh ones would have moisture in them, which could be bad for the lens, but it seems that fresh ones would also have more of the antifungal properties than dried leaves. Does anyone know anything about this? I'm really not even sure how well this can work, but I figured there wouldn't be any harm with sticking some leaves in my camera bag given my basement location. Note that my lenses do not have signs of fungus, I simply want to extend their life expectancy, and possibly give them a spicy scent.
