i browsed thru the forums here abt dry cabinets, and being confused by different recommendations from different dry cabinet manufacturers, thot i'd asked Canon about their recommendations. as expected, they won't commit to specific RH settings (they say its subjective, and understandably so) but here's what i found out on what they practice with their own equipment. thot i'd share.
* they store their cameras/lenses at between 40-45% RH (they are NOT specifying this but its what THEY use).
* accessories like plastic stuff (eg, flash unit), fabrics (straps, lens pouches, flash cases) & batteries should not be stored inside a dry cabinet.
* camera body/lenses should be wiped dry and aired after a shoot before storage.
* fabric/leather straps soak up sweat and moisture and recommended not to be stored in dry cabinet
* should not leave cameras/lenses in dry cabinet for extended periods as it does (slow) damage to plastics/rubber - in other words, USE your gear regularly.
these are recommendations on taking care of your photo equipment, not how to use your dry cabinets. it's probably negligible 'damage' if you've done any of the above (im equally guilty) but they do make sense, for the long-term.
