FUCKING FUNGUS Anonymous
before buying my first DSLR i decided to check if my grandparents had any old lenses.

turns out they had a Minolta AF 50mm f/1.7 and Minolta AF 28-135 f/4-4.5.

They both have some fungus on them though. I'm still probably going to go sony, but what are the downsides of fungus? how much worse is it going to get? I shot with the 50 for a semester last year for a photography course never knowing it had fungus on it so it cant be that bad right?

I can't get a picture of the fungus since I dont have a camera that can focus manually.

pic is the 28-135

well as you can see i have problem enough focusing on the outside of the lens. getting a clear shot of something inside lots of glass would be difficult.

thanks for your comment, but how do I prevent it from getting worse? If I can't control the temperature or humidity of the room I'm in, is there a special way i can store them, or some kind of case that will prevent things from getting worse?

I think leaving them in the sun might do it. Fungi haet light. Which is ironic, then, that they attach themselves to devices designed to transmit it.

Store them in anything that 'breathes'. Good examples include: a soft nylon camera bag, a tshirt, open air far away from a window. Bad examples include: ziplock bag, metal case, wood cabinet (unless it's expensive and humidity controlled).

Most lenses have different anatomies, even though most follow a similar formula. Go to wikipedia.

Go look at the detailed technical datasheet for pretty much any lens. There should be a diagram.

The fungus itself shouldn't get in the way, just as dust doesn't. The problem is when it etches grooves into the lens, which as far as I know cause loss of contrast and flare, just like a scratched up lens.

I've heard leaving a lens out in the sun will make it melt and shit. as in the lubricants will expand and it will fuck your lens. is this true?

Never heard of it. Putting your lenses in the sun is a pretty commonly heard way of getting rid of fungus though.

Maybe this is a really twisted version of the very true stories of cloth Leica shutters getting burned when you leave your camera uncapped in the sun.

Plastic and rubber can be damaged by prolonged sunlight exposure

that would explain some things. birds of a feather flock together, they say.

How about using an ozone generator, such as an ionizer. Kills even humans.

Or try using an UV lamp. Not shure if it would do anything to the plastic. But Ozone is a real killer.

You need to get them professionally cleaned now, end of story.
