Have you seen or considered airtight cases like Pelikan?
I used to live in a share house 10 years ago straight out of Uni and I was given my first Nikon hand me down a F70.
The lenses were ruined by Fungus. I stored them in the bag with “salvaged” small satchels of dehumidifier bag and was kept in my closet (from shoe boxes).
The flat had mould in the walls (we lived in a valley).
Some years later when I got a new D100 and some lenses the first thing I learned was caring for the gear. It worried me to the point I moved flats
D100 was a lot of money only a few years out of Uni.
Pelikans are airtight and "bomb proof"
Airtight yes I tested it
Bomb proof (I did not test)
I was lucky and bought two second hand from the same eBay seller and had it shipped to Australia. The key word SHIPPED not airmail
8Kg for one case 15 Kg for the other
I also use 400 gram aluminium canister of reusable dehumidifier for each case. I just put it into the oven when the indicator tells me to reactivate. For a few hours at 200C
No, I do not take the pelikan cases about with me. It is way too heavy. But it is a great place to keep the lenses and body.
It did cost $370 all up Inc shipping but as my glass collection increases the few hundred I spent on the case is nothing (at least I feel better).
Most importantly as my glass collection get bigger (and it is no way near the number of lenses some members on this board have) and hopefully in the future when I can replace my lenses to VR spec. I know as long as I store them in the case I am safe from fungus.
......Have you tried selling (to upgrade
) a mint Nikkor VR or Canon L or Sigma EX lenses with mould, than I tell you Pelikan or other Airtight case is a godsend.
Also you will have the case forever barring fire
PS: Some members might remember I did have a fungus problem with my 35mm f2. I left it in my garage by accident for a couple of month. So if you invest in an airtight case USE it. A hard lesson learned twice.
