Why didn't you insist to have the fungus removed? As long as you are paying for the servicing, I don't see how they can refuse to clean it for you.

I'm stumped by this post. Why waste your time to go service centre, say hi and bye? Since you are there, warranty also there, go clean lah. Few fungus one day will become big fungus. Ever heard of evolution? By the way, I heard if you put a lens with fungus together with fungus-free lens, you will spread the 'warmth' to the others....

FYI, lens clean or fungus cleaning is not free, even it is within warranty period.
the cost could be $100 to $200 for just two small spots, it is a sound advance given by the service center, since it does not show up on the images. but on the other hand, if the fungus are too bad, there is no use of cleaning it, the coating could be already badly affected.


btw, fungus spore is air-borne, they could be already land on all our lenses at the moment we take out our lenses from the packaging box, just waiting the right condition/ environment to mushroom.


anyway, why we always recommended use a dry cabinet? cos by the time you notice you really need it is always too late.

Fungus will only grow further if the conditions are supportive. Since TS got a dry box (and provided he maintains it properly at lower RH) there's little chance for growing and affecting other equipment. Fungus growth is not Evolution. Better check again the meaning before using a word :)

I believe the word is "growth" not "evolution"

Well, I have one lens that gotten fungus on the inner side of the front element. A few days of sun should kill it but unfortunately, the residue will be not disappear. Still have to sent it for servicing to take apart the lens and clean out the insides. The ironic part for me is that the infected lens was not the ones I left lying around unused for months, but the one I seldom used but brought out for weekly shoots.

Perhaps TS could kill the fungus and leave it as that since the fungus is not affecting IQ

How we know if the fungus is killed?
Did u service your lens or just leave it?
Does your fungus affect photo?

Nobody knows, unless you want to open up your lens and use a microscope to examine the lens elements has any new fungus spore.


a few tiny dots won't show up on photo, the fungus has to be very bad like spider web covering the lens element than you will notice the difference from the photos.

cleaning the lens does not prevent the fungus from grow again, it will come back when the condition is right for them to grow.

do regular maintaining of your dry box or just get a dry cabinet to slowdown the fungus from growing.

is fully automatic, just make sure the setting is correct, remember to close the door properly, don't off the switch, check the power still running and the humidity level is correct occasionally and remember to pay your utility bill too.

What lens is it ? if its a cheap lens then dont bother ( if the cost to clean it is more than 60% the cost of the lens). Keep it it dry box and use it as long as you can. if you manage to control the growth by keeping it in the drybox or taking out in the sun it will take a while before the fungus can spread enough to make an impact on the images.

hi kane-rulez, mine is sigma 17-70.
so if i control the growth and service the lens when the images get impact, will it be ok?
or service now to save the lens?
