I am newbie. Just got my 1st dslr and I got a dry box to keep the camera and lens to prevent fungus.
Then something hit me, and I have been pondering it ever since.
Say you got your lens, then you screw in the UV filter to protect it.
Then the air between the filter and the lens is at normal RH level.
When you put the lens inside the dry box/cab, the air outside the filter and lens body will drop in RH, while the air btw the filter and lens is still at normal RH.
I assume that the filter's thread will form an air-tight seal with the lens thread.
Does this means that to properly protect our equipments, we should unscrew all the filters, lens cap (front and rear) and body cover before placing them inside the dry box/cab?
