Following my recent RX10 mould issues, I was discussing the problem with someone at The Real Camera Company in Manchester. These were the people where I sent my RX10 to the repaired and who did such an excellent job.
It appears the common approach of many photographers is to store their equipment in camera bags. Typically, the camera would be left in the camera bag between outings. A bag which would usually be zipped shut and sometimes be damp from being out in the field. What better conditions for mould to thrive than in dark, damp conditions with no circulating air.
My own approach to storing camera equipment as to keep it in a camera bag but with the top open and use silica gel sachets to limit moisture. If the bag became wet I would remove the equipment until it had been dried for at least 48 hours. Thinking about it, I decided this wasn’t good enough given the cost of equipment.
This is when my wife had a great idea and suggested this storage.
This was purchased from Costco for around £20. It’s actually storage for shoes but it fits camera equipment perfectly. I can fit my Fuji X-T2 + lens in one of these compartments. I can fit all the Fuji lenses in the next and so on. I now have all my camera equipment and key accessories in this 4 x 3 unit. Everything is easy to get at, the units are semi-transparent so exposed to light and air can circulate freely.
Let’s hope this keeps mould away.

Interesting! Now you’ve got me thinking because unless my camera or lenses are wet they stay stashed in my camera bag, even if it is wet or damp. Not a great idea really so this is a good point you’ve exposed here. Thanks.
Your welcome. Some people may consider me over cautious but the mould incident keeps coming back to me. It’s a risk, especially if you don’t use all your kit frequently.
It’s a great idea leaving everything open for a good airing out including “when did you get that lens?” kind of conversations.
Now you have made me think. It’s not just when did you get that lens but “how often do you use all that?” I may have to modify my strategy.
Consider buying some cat litter crystal’s, find some lonely old socks who have lost their partners and fill them with 250grams of the crystals. Absorbs moisture and don’t smell at all.
Excellent tip. Thank you.
I could tell from your post that you do not live in California. No problems with humidity here in most places except for the coast. A folded wet towel dries out in a few hours. I wonder if so much dryness is not bad for camera and lens elements.
