AAARRRGGHHH!!! The dreaded fungus attacks!

AAARRGGHHHHH!!
I just noticed one of my favorite lenses, my beloved and otherwise mint A70-210 f4, has been attacked by fungus. Last time I used it was a few months ago and it was perfect. I already sent a note to Eric. I hope it can be saved.
I checked all others and the Vivitar 28mm f2.8 has what seems to be the start of it. I read that if exposed to the sun it can stop it from growing. Any advise?
Fortunately the 3 most used (18-55, 55-300 and 50 f1.7) are in a separate bag and I use them almost everyday and they seem to be fine.
Any general advise on the topic?

Thanks,

Are you using any desiccant in your camera bags to control excess moisture?

+2 for the silica gel packs. You can get them online in various sizes. Put one in each lens/camera case and in you kit bag/storage area.

You live in (Puerto Rico) a hot/humid area, so these are a must.

Thanks!
I was using a small silica bag but evidently was not enough.
The lens is on its way to Eric. Hopefully it can be saved.

Goods news, Eric will take care of it! The silica bags need to be replaced frequently. Some can be reused I think if you microwave them.

you can also blast some with a hair dryer on low for a bit, anything that will cause heat will remove the moisture
they are cheap though so it's no big deal

How many of the silica packs in a camera bag are enough? Is having 17 or more in one camera bag considered overkill? I have the Pentax Slingbag and have about 3 or 4 of them in each compartment.

As funny as it may sound, it is true. Everytime I get one with a lens purchase or whatever, I just toss it in my camera bag. The collection grew.

The silica packs are designed to cover a cubic volume of space. The bigger the pack the bigger the space it covers. Looks like you are well covered!! Overkill is better than fungus!

In P.R., it may be like Florida in that jell packs go from blue to pink really fast if not in an air tight container. I have trouble with even large metal packs holding up in a regular bag between recharges.

While I love the tropics (I was a Floridian for nearly half my life) this sort of thing is why I have a great deal of trouble buying used gear from wet, hot environments.

Perhaps my fear comes from ignorance, but I feel like I'm just asking for trouble buying from the tropics, especially after hearing how people get the dreaded fungus in spite of good efforts to control it.

I guess I'm now waiting for my dream FA 31 to come up for sale in New Mexico!

To the original poster ... hope your lens is restored!

First, sorry to hear about your lenses and I hope they can be saved.

Second, thanks for the link to the SilicaGelPacks website.

Finally, a question: What should be done about the case in which the infected lens resided? Is there any worry about continuing to use it or should it be thrown out?
