Clean inside lens fungus


If you realy have fungus in your zoom lens, you can't do anything. If it does not show on the pictures, just keep the lens dry. (use silica gel) If you want it it be repaired, it will cost more than an new lens.

HOW TO REMOVE FUNGES IN LENCESS.


Fungus is difficult, if not impossible, to remove from lenses. It'd require total disassembly of the lense by an experienced tech, cleaning, cleaning of the barrel, possible re-grinding of the element cleaned, re-cementing of the elements, re-aligning of the elements, etc. It's a time consuming, demanding, and technially requiring job, as well as a very expensive job. Unless it's a VERY rare and expensive lense, it's pointless to undertake. Fungus does not, or 99% of the time doesn't, form on the outer lens surface (though it appears that's where it is), it's actually inside the lense.

What should i do?...my tamron 17-50 began to have a fungus.


Well, that's a great lens and most definitely worth the cleaning/service. I don't know where in the world you are but fungus growing inside a lens is only heard of in high humidity environments and can happen fairly quickly. Are you sure this is a fungus on the inside and not just a clouded smear on the front element? If the lens is having a problem then the camera won't be to far behind. To answer your question more directly "what should I do" my suggestion is to send the lens to a authorized Tamron service/repair center/depot for cleaning. After which get a few of those little moisture absorbing packets and place them in with your photo gear to help reduce the moisture.

Sigma 70-300 4-5.6 DL has some fungus & blur


Fungus etches the glass. This cannot be fixed by just removing the fungus. The lens has to be resurfaced, calibrated, coated and
well, you get the idea. lots of expensive precision equipment and a jig to recalibrate the focusing after you do all that.
Another 70-300 on Ebay is much less expensive.

There's fungus inside the rear element - how do I remove the glass to get at it?


Any way you want.
The problem with fungus is that it etches the glass, which then has to be replaced. Unless you can find a stockpile of Contax 50mm f/1.7 Planar T* lenses for a replacement part, you'll have to buy another lens.

Let alone the recalibrating after replacing the lens element.

Sorry about that.

Sigma 500mm lens need to remove funges from inside lens,but funges not showing on photographs is it possible to strip


That is a manufacturer repair. While you may be able to remove the fungus, the fungus may have etched the coating on the lens and still show . The best way to fix that is replace those lens elements that are effected.

Hi, I have a nikon lens that has fungos inside the lens, is there any way to clens it?


Hello. Sadly, the answer is no. You must have the lens repaired by a tech. If the fungus is on the front lens element, trying to remove the lens for cleaning will invite disaster in short order. There are hidden set-screws, grease, precise distances, and sometimes timing positions involved. If the fungus is severe enough, the actual glass element will have to be replaced because fungus can etch itself into the surface! The key to preventing fungus is to NOT store the camera/lenses in a cool, dark, place like a closet or drawer. If you do need to store the system for a longer period, remove all batteries, use a desiccant(the little packet that says DO NOT EAT) which absorbs moisture, and then close up everything in a sealed bag. This keeps any extra moisture from entering the sealed environment of the bag while the desiccant keeps the interior extremely dry.---Hope this helps!---Rick

Fungus inside lens


if it's mild then it won't have any appreciable effect on your photographs, so leave it until it's worse. The fungus can be slowed or killed by sunlight or by exposing the lens element to ultra violet light.

If it's really bad then you have to decide whether it's worth a professional strip down and clean. You'd have realistic two choices: to remove the fungus and replace all lubricants and canada balsam lens cement with modern antifungal equivalents but leave the damaged lens coatings as they are or to do the same and also have affected lens groups replaced with new ones or have the old ones re-coated. The first option is expensive, the second option is very expensive.

Hi, It appears there is a small amount of fungus inside my lens, and when taking a picture, it comes back very dark. What would a possible remedy be for this? Many thanks Jon


This is actually a very common situation for older lenses. You should take the lens to a trained technician and have them clean the inner elements of the lens. Often times they can, if the fungus isn't too bad. In extreme situations, they will need to replace the element itself.
