I have also called a camera shop who undertakes this kind of cleaning jobs and he said it will take atleast 7 days and price can vary.

Does it actually takes this long ? is it really expensive ?

I heard keeping the lens in sunlight can help - shall i ?

Re: Fungus on Lens - Help me

It looks like fungus and appears to be very pervasive. Was the lens ever submerged in water or subjected to extreme humidity or spray? Judging by the front element condition, I would expect the interior elements to be similarly effected. I would replace the lens. UVC light can kill fungus but since the glass elements in the lens block UV light, it will have no effect.

Re: Fungus on Lens - Help me

Hi,

I am no expert by far, but seeing as you only have one other reply, here is my 2 cents:

- yes, that looks like fungus.

- it may not affect image seriously, mainly contrast, depends on how the other inside and back elements look

- gt the repair guy to give you a quote, which lens is it, the quote may be more than a replacement lens from Adorama or B&H or Cameta Camera (or Ebay). However, if an expensive lens, may be worth it. Or, the quote may not be much, I wont know,t he repair guy will.

- A lens does not ened to be immersed to have fungus. A humid environment and time will do this.

- In future, try to acquire a few packets of silica gel (electronic stores should have a few to give away.Keep them in the camera bag when not in use.

- Siilca gel is a drying agent and will keep you lenses clear, but you will have to refresh it by putting in oven (not microwave) every few months (assuming packaging can take the heat (not plastic obviously).

- Silica gel is also poisonous by the way, only if you ingest, not to handle (I say this just in case you have little ones around).

Hope that helps in some way. No liability accepted for wrong information...

Re: Fungus on Lens - Help me

something that hasn't been said and that is fungus can also etch the glass, making it almost impossible to rid the lens completely of the "fog"---get a quote but I would toss it if any large percentage at all of new or good used.  By the way just keeping your lenses in your bag can lead to this, in fact5, almost assured of that if for long periods of time---ron s.--

Re: Fungus on Lens - Help me

Fungus or not, I would try to clean both front and rear elements with some good lens cleaning products first, then check the inside by pointing it towards a light source and looking through from the rear element.  If it is a G lens, there is a lever on the lens mount that you can move to open up the aperture blades.  If there is indeed fungus or dust inside the lens, you might want to have it serviced.  Whether it is worth the money, you have to decide.

Electronic dry-boxes are now very affordable.  It is therefore highly recommended to have one.  Once you have the right humidity set, you don't need to worry any more.  It can also be used to keep dry other personal items, not just photographic equipment.

How can I prevent fungus from growing on my lens?
The possibility of fungus growth can be minimized by storing the equipment in well-lit and well-ventilated environments with moderate temperatures and low humidity. We recommend removing equipment from carrying cases during storage and not storing cameras or lenses with clothing.

Re: Fungus on Lens - Help me

Once you have Fungus in a lens, it can not be cleaned out, it is normally in the Bolsam between the elements.

In truth its a replace elements job, but a new lens it will possibly be cheaper in the long term

It sounds as though the lenses may have been stored somewhere damp..

My suggestion is next time use this http://www.walmart.com/ip/FG01K-DampRid-Refillable-Moisture-Absorber-10.5-oz./15033112 I buy them at walmart and they are cheap and lasts up to three months. You can also buy selica gels but are harder to find. I put two damp rids in the closet.

Additional products include Drierite and stuff used to dry flowers sold at the local craft store like Joann's or Michaels Drying Crystals .

I have cleaned ~20 lenses with fungus. Sometimes the glass is etched permanently. And on one lens I tried to clean, the fungus was inside a lens group - in the glue. Canada balsam is not used in modern lenses. But even on my old lenses with most likely Canada Balsam I did not find fungus inside there.

The USA where you live is a big place.

Leaving camera gear in a canvas camera bag in a "freeze thaw" climate, living near the sea or a big lake, or places where you get high humidity increase the risk of fungus starting to grow.

I cannot say how or why fungus started to develop in yours lens, but as it has for the future I would look at ways of reducing the risk.

High humidity will lead to fungus. If for example you regularly shower, and the bathroom becomes foggy inside, when you open the door, that damp air will spread out, and the damp will settle on cold surfaces, including cold lenses at the bottom of cupboards. Drying clothes indoors is just as bad. The safest way to store lenses is in a sealed box, with large pouches of silica gel, which you heat to drive off moisture when needed. Some people say that once a lens has fungus, it should not be stored with other lenses. I do not know if that is true, but if a lens gets fungus, the humid atmosphere is the issue.

The cost to treat a lens varies. It might need a new lens element, or it might just need cleaning. Nikon will charge more than a local independent camera technician.
