Do you also have damp / fungus in your lens

[JR1]

It appears to be a sign of the times that more and more people in fact according to LCE MOST people will find that their gear has fungus in the optics.

I checked mine today and yes, all the lenses have, from 6 month old ones on.

Now if you are an honest person, check your lenses now and see what you have, look through BOTH ends at a bright white light.

I do use large packs of silica gel, to no avail, I am now setting aside a place for a non centrally heated area with a de humidifier, also take more precautions when in damp areas. As I am setting aside money for such lenses as 70-200 f2.8 Nikkor, 12-24 Nikkor etc I am concerned, who isnt.

Climate change!!!!!

[mknittle]

In other words is there a fungus among us?

Man made Climate change is a scam to control the people.
Check weather history. do not trust the media!
Those are my final words on the subject.

Holy crap another Conspiracy Theory to control the people. Climate change has nothing to do with the media - check the scientists - what they've been measuring IS the weather.

In any event, fungi in lenses has nothing to do with the global climate or the weather.

And there might be a small chance that the materials used in lenses or the methods of fabrication used makes them more susceptible to fungal growth. Fungus has to get into a lens in order to grow - a zoom lens with air being sucked in and expelled could be more susceptible.

Just do some research on your own! The media is full of lies No conspiracy but truth. Don't be a sheeple. this applies to everything!

Ah, yes. But scientists are driven by research grants. No research grant, no research, no job!

Exactly. I used to work for a company that built custom scientific testing machines. I lost a lot of respect for what passes for science during those 15 years.

Eh, isn't it the scientists who have demonstrated beyond all reasonable doubt that climate change is happening and than humankind is primarily responsible? I feel that to take any other view is dangerous and damaging. Our great grandchildren will not thank us for ignoring the issue or pretending it isn't happening. We are killing our environment.

As to the topic that started this thread, I've never heard of fungus in the lens. What is known about the extent of such a problem? Is it widespread? Is it correctable?

While I realize you feel strongly on the subject, you would gain more credence with fewer commands and exclamation points, IMHO.

OT, but it would seem that the media, at least here in the USA, is controlled by the corporations and happily feeds us mis-leading cr@p all day long.

Which is why I watch FSTV and LINK and RT for the real stuff . .

It isn't uncommon but most new lenses are better sealed. Until they get older. For some particularly horrific examples, try here .

Good link, that, @Aaorsa.

Thanks.

I have seen what I have seen and no amount of rhetoric form the media can change that. so there is no reason to go farther on my part. Other that what does "Climate change" have to do with fungus in a lens. There have and always will be fungus in damp climates.

How timely Jeremy. This past weekend I took a look at the front of one of my kit lenses while I was out in the field and noticed some white spots that were not on the outside of the glass. The thought of fungus crossed my mind and after reading this article I will take a closer look. Unfortunately I am in Hawaii, one of the places cited in the article as having the worst cases of fungus that the author had seen

If the lens has a fungus I'm not sure if would be worth the time or money to 'clean' as it is a kit lens but I don't really want to replace it either from a cost perspective.

Certain microscope optics have been known to be given an anti fungal coating. I had a bit of a problem in that direction recently. A Canon fit Sigma to 500mm zoom. It truly has hardly been used at all just a few times after the EOS 300D / Original Rebel was introduced. To big and heavy to carry around much. It's always been kept in it's case. Came to sell it, mint for obvious reasons and had an email asking about fungus etc. Decided to have a very careful look and found some dust inside and 2 small patches that might be fungus. Problem is I have seen fungus on microscope optics. Depending on how extensive it is some of it has a coarse spider web type appearance. This leaves me wondering if it's a another type of microscope optic problem. Zeiss in particular have problems with 2 cemented elements delaminating in places. Another cause could be a coating problem - glass not completely clean when it was coated. To be honest these marks might have been there from new. I don't generally look that closely at a new lens.

Global warming. I'm a bit agnostic on the subject but would note the following points.

The global warming swindle people who were taken to court did make one telling point. The CO2 we add is a drop in the ocean compared to other sources such as rotting vegetation. I used to have an interest in short wave amateur radio and I associate high sun spot activity with great weather. Have to wonder about deforestation too. Rain forest wise that is bound to change the climate world wide.

Water vapour has a significant climate change effect. There is most certainly more of that about in the air than there was some years ago.

Can't put a date on this but some time ago a person who was heavily into beetles surveyed fossilised ones on the west coast of the UK where the gulf stream hits. It seems certain species of beetles only live in specific temperature ranges. His finding were that the gulf stream turns off from time to time. From memory sub 1000 year intervals and erratic.

The last one is something put trivially by a teacher at school. It's always snowing at the poles so why isn't all of the water there? Sounds daft but over millions of years in many way it aught to be there. If not there must be some mechanism from time to time that prevents this. Einstein wondered about this too. He thought that the ice caps built up so much at one point that the weight tilted the Earth's axis.

Last but not least scientists. They earn there money largely via grants. One on the telly pointed out a problem. Say some one wanted to study squirrels. No chance what so ever but if they restated it as the effects of global warming on squirrel's eating habits or what ever they would almost certainly get one. There are also the problems of fraud and reference miss uses that crop up in the news every now and again.

I could go on but wont and didn't start this anyway.

Spots are sometimes dust that has been drawn in and distributed by zoom operations. Whenever elements are moving, so is air. I periodically dust the back of my lenses even when they have a cover on them.

[IzzieK]

Thank goodness the only fungus I know were in my garden... not on my lens.

[Shadowman]

Probably already mentioned, but a few years ago there were estimates and measurements stating that the Artic ice caps were melting, now the research suggests that they are growing again. Now I believe scientists will estimate their theories on the cumulative years of melt/growth.

[shreds]

No signs of fungus on my weather sealed lenses. Maybe that is significant? Still they do cost in the first place.

[ajohnw]

If they are zoom lenses good old vacuum makes sure that air gets in and out as the lens changes length, probably when internal bits as well. That air can be drier or wetter than what was in the lens.

All my lenses show varying degrees of fungus and have done for a few years. In my case I would say it is simply due to the humidity and atmosphere that I live in.

Gave up worrying about it a long time ago because there's nothing you can do other than a professional strip down.
