I got two fungus infested lens, one kept in an airtight tupperware box with an old slr.
The other lens is kept in a cupboard, also got fungus, but at a lesser scale compared to the one above. Trying to clean this one up, since the dissasembly seems fairly simple.
Both lenses are attached to a body. Weirdly enough, my 50mm 1.8 kept next to the cupboard lens seems fine. I've since left my 50mm on my desk with plenty of sunlight, but now i have to deal with a dusty camera+lens.
For fungus prevention purpose, is a drybox absolutely necessary? Does it work?
Dry box definitely works in preventing growth of mold. I bought one Aipo brand dry box few years back. Although I don't own any camera gears, I stored some of my flashlight and other gears in the dry box. Some flashlights have a layer of anti reflective coating on the lens, so it will give a purple-ish hue when viewed at a certain angle, just like camera lens. Those flashlights which are stored in the dry box will remain fine yet those I left in the open air will develop mold over time. So sometimes I will wipe the flashlights' lens when spot of mold starts to sprout. The same goes to disc based media as well. The UMD, when left in PSP, fungus will start to thrive on them too. So I just keep some disc in the dry box. Too bad I can't stuff all of them into the box.
For humidity setting, I just keep it at 48% is good enough. I put it at 40% before and feel that might be too dry, which, might dry up the grease in the o-ring in some gears.
With humidity issue out of the way, there is still one issue for me though: heat. The gameboy I stored in the dry box had developed a black spot in the middle of the screen. The temperature in my room is hot, so the electronic gear stored in the dry box will deteriorate faster over time. Keeping the air con on for 24/7 is impractical, so I will have to come up with a cooling solution for my dry box.

What type of dry box do you have? I searched on Amazon. Price range $80-$400. But when imported, should be tax and DHL delivery.
Just buy from local store is good enough. For starter, you can search for "dry cabinet" on Shashinki or Shopee.
