More Fungus . .

. . 'tis the season . .

Ted you are lucky if you get seasons for it, it grows away all year round here

It's slowly creeping across the back of my D300 LCD screen, perhaps that is as good a food source for it as my lenses

Indeed, the season here in the Texas Gulf Coast area is pretty long but can't compare to y'alls, I imagine.

Sorry to hear that, Grahame.

There's some anti-fungal discussion going on in Sigma-land involving UV which you might find of interest.

I have over the years read and followed many of these discussions Ted, and often chuckle at some of the ideas.

An example is to leave your lenses out in the light because UV is an enemy of fungus.

OK, so to do that and to have any affect would require the lens caps to be left off.

But my lenses would then fill with ants and dust, but I'm sure someone here will know the formula that proves whether the best light transmission and hence IQ is through dust, fungus or ants

But on a more interesting observation what I have noted is that my Tamrons are not suffering at all but every Nikon is?

A gent has just showed up over there suggesting something like that. Another gent has recommended kitchen foil underneath to bounce all that UV back and forth inside the lens for max. deadly effect (and to prevent scorch marks on the window-sill).

Perhaps the Nikons have fancier but more edible coatings?

Anyhow, of my five Sigma lens, only 3 have fungus that required a clean and, of those, only one has a tiny speck starting on the underside of the object lens. Tomorrow, I'll be checking my filters . . .

The lenses have moved today into the living room from my non air-conditioned bedroom.

And I looked at the thread and thought that it was going to be about mushrooms and fungi, I suppose that I was right, only a different sort.

Sorry to disappoint, Ken.

Here's some growing out of an oak tree stump in the yard. No idea what it is but it's beginning to stink pretty bad . . .

Me me, Ken and Ted -- I thought of Mark's (Marlunn) fungus-es and fungi, whatever the right term is here...Anyway, Ted and Grahame, would the cause of the fungus on the lenses be because of the heat and cold that causes condensation inside the lens and/or camera? I need to understand the underlying causes...I just got my camera back a few weeks back when I had my mirror-up caught up in the up then when Bill and I went on a cruise, I noticed that I have condensation at the front of my lens everytime we go down on port while inside the ship, it was OK...I wrapped my Nikon in a ziplock bag and am very hesitant to use it from then on. It is not the price of the repair though that too, that bothered me but separating my camera for a few days or weeks while on repair is not really on. Now I am scared to touch my camera --I think I was traumatize enough for a week then. I still haven't touched it since we came back...and an iphone is not good enough for me to use yet...

Hello Izzie, Please take your Nikon out of the baggie immediately and put the camera somewhere less than 60% relative humidity (RH) but more than 30% (NOT in your fridge!). It will take a while but the internal RH will equalize to the external (talking a few days or even a week or two).

Some light reading, while you're waiting . .

I had! Two weeks after we came back from our cruise. I even forgot about it being there inside my backpack because life immediately took over. I have just started to live a normal life last Friday and to celebrate, the cleaned the house from top to bottom. I had not touched it since though. Maybe this month ... soon. Thanks for not answering my question...

Ok Izzie, in easy steps to help you understand the underlying causes

Inside the ship/hotel/office/house it may be air conditioned and cool and your camera body/lens will be at that same cool temperature.

When you take it outside in the heat and humidity the moisture in the air will condense on the cool surfaces of your camera. If you zoom your lens moist warm air will get sucked inside and also condense.

Imagine a glass of cold beer taken outside in the heat and humidity and what happens to the outside of the glass

To stop this from happening you can put your camera in a sealed bag inside the ship, take it outside and WAIT for it to reach the same ambient temperature as the outside.

As for fungus it can be in the dust in the air and it enjoys moisture

I guess I have to do that before I go out of the house everytime too as our house is centrally heated and cooled all year round. Just as a sort of precaution...thanks, mate! That was helpful.

Sorry, Izzie, I should have made it clear that my links contained the answer and more.

You asked "would the cause of the fungus on the lenses be because of the heat and cold that causes condensation inside the lens and/or camera?".

The fungus only needs humidity above about 60% to help it grow - actual condensation is not part of it's life cycle as far as I know. Of course, if condensation is occurring then the relative humidity is 100% by definition. There might be a value below which the fungus goes dormant or dies: if so, that would be a good thing but I haven't really researched that aspect. Might be in one of them links - perhaps the Zeiss one.

BTW, 'humidity' and 'relative humidity' are related but they are not the exact same thing.

Sorry for the late reply...and thank you very much for getting back to me despite my tongue-in-cheek response to you at the end of my post... I took time to read your links as I have to find time for them somewhere in between getting back to my normal life. Yesterday was the first time I touched my camera again and I still feel too careful so I have not taken it outside yet. I have two weeks yet before we leave for Nevada and to make sure I do not have to change nor open any 'doors' on it, I bought a 200GB Sandisk for this trip knowing how cold it might be when we head home for that week of driving holiday. Thanks again...appreciate it very much.
