    I have kept my camera in a dry box with thirsty hippo for the past 4 years. The hygrometer will point to 0% if I am starting a new thirsty hippo. It will eventually go up to 40% after a long time, then I will change to a new hippo. So far, my camera is still functioning well.
    The rubber or leather parts will dry out from what I know. Some say the lubricants and oils will dry too, but I not too sure.

    I just keep mine inside a bag with some sillica gel. Go out a few times every two weeks to shoot, so dry cabinet not really needed for me.

LOL! if it goes way below the requried level then it sounds scary also.

    anyway for those who are using silica gel in dry boxes, usually how low does ur humidity level goes to? will it keep on taking in moisture until extremely low lvl? tis's my concern.
    Yes, opening up the box when it drops below will help. I don't know how low it'll go coz I try not to let it drop too low. Thirsty hippos are great when I am moving things in and out of the box; once it drops below, opening the box and taking it out will raise the humidity level a bit, but still acceptable. I used to use entire can of silica gels in the box; now I keep that sealed and use only a bit so that (i) don't need to open box and close back that often and (ii) when I do, not the entire batch of silica gel will be used to absorb and I can add more when needed from the unused batch.

    I also rotate usage of my lenses so that none of them will stay unused for long time.

    Excellent, you are the 3rd person who experienced the real stuff about low RH on your equipment.

    The lubricant drying thing, it is a myth, have been bust. Search around and you will know.

    Plastic, glass, metal case and circuit board cracking as believed by many, the truth will be out in time.

    hi,

    my own conclusion is lol! leave a slight gap when closing dry box if the dehumidifier is too strong. so far so good for me. if using silica, trial and error.

    btw, i'm a guitarist too, and usually many of us use zorb it. coz there a minimum that it can go. but whether or not its until acceptable lvl for cams or not i'm not too sure, but no harm trying and i heard its available at maestro guitar shops. quite cheap also. worth a try and it can last damn long if i'm not wrong!

    enjoy guy!

    Hi Guys...to put the myth to rest once and for all.

    If you own a camera made after 2000AD, chances are the grease used are synthetic ceramic grease which will not dry out and has good thermal properties so that it does not seize up in winter or becomes very viscous in summer. Besides, this type of lubrication will never dryout below 100deg C nor is it affected by low humidity.

    The rubber seals and body coating for more ex cameras are made from neoprene rubber which is inert and will not harden, crack or flake etc.

    Having very low humidity levels will not kill the camera or your lens. Nasa has cameras in space with zero humidity and its cameras are still working. The astronauts went to the moon with Hasselblad and Nikon cameras more than 50 years ago.

    The
    problem is the moisture embedding into your camera when you use it and hence when it dries out, the remaining moisture will creep out and smear the lens etc. There's no harm to keep it within 45% RH or lower. In fact, there's no harm if you don't keep in a dry cabinet either provided you use it often enough. I leave my D700 on the desk throughout the week and take it out on Saturdays for a quick spin round my house. After a few months, the only problem I have is dust which is removed with a small vacuum cleaner.

    Well explained though the Nikon D2Xs and D3S DSLRs utilised by NASA astronauts in the ISS are actually lubricated with Braycote Vacuum Grease.

    Anyway I keep my camera bodies and lenses in one of this.

    wth o.o 20rh is like. u can store chinese medical herbs.

    40-46 is the way to go. anything lesser, the lubricants in ur lenses may be affected and end up damn stiff. tat was an advice given to me by one of the sempais

    Must DIY dry box be all air-tight? Mine isnt air-tight and i have a thirsty-hippo inside. I take my cam out every evening. Is it alright for my cam? Thanks!

    I am using an air tight tupperware box with silica gel measured by a musical hygrometer. This way, I will keep the humidity out of the box.

    Depending on how big is your plastic box and how accurate is your hydrometer, 27% is seldom achievable.

    Even if you manage to get down to 27%RH, the dryness will not affect your camera much. In my house, it is 31% RH in summer and 47% RH in winter and my cameras are still OK. Modern day cameras are able to withstand such dryness due to the fact that a lot of plastics and synthetic grease is being used as compared to long ago when manufacturers used mineral oil. Even mineral oil has a low rate of evaporation.

    In a word, yes, 27%RH is still OK.
