Thirsty Hippo (but apparently there's talk that its TOO dry)
Dehumidifier Lamp in a cupboard (DIYers)
Others! (wow there's a 5th option? post it here!)
I also rotate usage of my lenses so that none of them will stay unused for long time.
Someone from Singapore also asked that but seems like no one really has the "answer".
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!
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.
Braycote Vacuum Grease.
Anyway I keep my camera bodies and lenses in one of this.

where to buy good and cheap dry box and silica gel? hehe
got this box?
I just get a plastic toyogo box and some dehumidifier from daiso. RH at 27%.
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.
