What can we put in a 30L or 50L dry cabinet?

[Digi-Cabi]

Depending on how one squeezes or stack their gear, one can keep a varying amount of gear in their dry cabinets. As a guide:

The 30L can hold: ~1-2 bodies, ~3-5 standard lenses, ~1-2 flashes comfortably.

The 50L can hold: ~1-3 bodies, ~3-7 standard lenses, ~2 flashes comfortably.

[The Miracle]

It'll be quite cramped according to your suggestion.

A 60L or 80L will be more comfortable. For ~2bodies, ~5 lenses, 2 flashes and misellaneous stuff.

The bigger the better!

[Brown Bear]

Used to have a 20L, non-electric type. One can really squeeze quite a lot of stuff, but you'll end up stacking lenses and bodies on top of each other.

Strong discipline needed to add just the right amount of silica gel each type the box is opened, else the humidity will either be too low or too high.
