Fungus migrating from lens to mirror/sensor?

[Acolyte]

Hi all

This weird thought popped into my mind recently:

Is it possible for the fungus infecting the lens to "travel" via spores into a dslr mirror box and grow on the mirror/sensor (when lens mounted on dslr)? And is it more possible for affected zoom lens than primes to spread the spores since the zooming action pumps air in and out of the barrel?

Asking this question as I've read threads advising bros not to keep infected and non-infected lens together in the same drybox in case of contamination, so wondering if it could work this way or not.

Any inputs much appreciated!

my fren suspect the same thing too... he is also a member on this forum.. not sure if he is reading haha...


he told me he is worried about borrowing or trying lenses from others... as he suspects fugus from others' lenses can affect your camera...

but i think if we try it for a short while, it should be ok.. not sure about pro long use of a fugus infected lenses overseas and u don't have a dry box....

Fungus spore are everywhere. In fact, there may be fungus spore on your lens or camera now waiting for the right condition to grow...

Yup was afraid of the exact same situation. Wanted to use an old manual focusing lens as a walk about lens but no visible fungus doesn't mean no fungus hiding inside de barrel. Later destroy the sensor den i cry. :cry:

Yeah i agree. But using an infected lens mean higher probability of getting spores into the mirror box right haha.

I think the chances are low. The mirror will be subjected to a lot of movement which will not be conducive for fungus to grow.

There's so much charged components on the sensor which again not conducive for fungus growth when used frequently. I m pretty sure when we expose our equipment there are already fungus spores all around in the air . So question is do we create an environment for it to grow roots on our optics ba

Therefore,the best way to prevent fungus is to use your camera...

Yeah, fungus spores are everwhere, including your dry cabinet. If you maintain low humidity then they won't grow.

Why worry about mirror/sensor? They can be cleaned rather easily compared to an internal lens element.

This is true, so why not put a fungal lens in your dry cabinet together with your 'clean' lenses?

Or u can be like me. Put a "potentially contaminated" film camera in a

2 X Thick Ziploc bags (those sold in army market for outfield that kind onezzz)
with a
Tea bag full of silica gel (put between the the 2 ziploc bags)

Squeezed out as much air, sealed tight tight

before putting in my dry cabinet. (i scared cross contaminate even though its was inspected by a professional to be clean already, sorry lah, call me hum-zi but i still kiasu, lol):sweat:

I wanted to buy a small dry box to keep it, but when I went down to both cathay photo branches today, they dun stock anymore sia, only the dry cabinet which needs electricity......stunned....:sweat:

When a lens is infected fungus it means the the fungus spores has rooted into the optics. And for the tiny spores to grow into visible fungus , you can imagine how much living fungus are there .

Even if you leave it in a dry cabinet , the fungus would disappear without proper cleaning.

As to why people don't leave fungal infected lens with other lens, In the dry cabinet . All I can say is , if there's a day where the fungus does grow on your other lens , and we still keep it in there knowingly , it like lppl. Cos we didn't tske preventive measures .

Nothing is foolproof also , the best deterrence is to use your equipment frequenlt and maintain it often

i have the same question too, cause i have old film cameras with fungus on the prism and lenses but i wanna store them in the dry cab too, so im wondering if its a wise decision?

In theory it should be ok since a dry cab is bad environment for fungus growth.
But personally, I wouldn't do it.

u can put the fungus lens separately on a diffrent level in e dry cabi . wrap them up wif ziploc for better protection.
