Florida’s humidity
1

hi,

i own a A7riii and wanted to know if I have to fear anything when I sometimes take my camera out from my apartment (A/C on 71 F) outside to 90F (95% humidity)?

More worried about the lens than the camera body. Mold can grow and condensation can be an issue.

Re: Florida’s humidity

As a frequent Florida traveler, no short term issues. If you can just leave your camera and lens in a bag under the camera warms up, it will minimize short-term moisture in the lens.

Otherwise you just have to wait under the condensation evaporates; can take a few minutes if you just keep you bag open. The larger the glass the longer it will take.

When you get back inside just keep in a cool dry location. You can use some of those gel packs if you want.

I shoot often in humid places, and these are some of the things I do:

  • Avoid pulling a camera or lens directly out of a A/C environment. Open the camera bag and allow it to acclimate slowly to avoid rapid temperature changes which cause condensation
  • Leave the hotshot cover on
  • Don't let a camera sit in direct rain for long periods of time.
  • Don't wrap a camera or lens with a plastic bag. It will inhibit airflow and trap moisture
  • minimize lens changes
  • Throw cameras and lenses in a dry bag after a humid day with a silica gel packet

By following these steps, I've never had any issues.

Yes, I live in Florida and you can have a problem (many years ago, before I knew, 3 lenses developed mold), Just pay attention to the advice given on the forum. Pack the camera bag, take it out of A/C into the car, possibly into the trunk, or back of vehicle, and let the equipment acclimate while in the camera bag. Also I use the drying packets in bags with each piece of equipment (camera, lenses) after exposure to rain or when moisture is a factor. If there is condensation on your lens, definitely use the drying packets when you get home.

Best of luck to you,

Sony warns about this.  Be careful.

You will eventually get problems if going in and out of A/C and high temp/high humidity and forcing lots of humidity condensation. I've lived in Miami, Hong Kong, and various places in SE Asia - so very familiar with this issue. Even with care to try and let things equalize, I've had an A7RII die of condensation water damage and developed mold on two lenses. In all three cases, Sony repair services (I'm based in Hong Kong) fixed the issues for a reasonable expense.

Best advice is: Keep your camera gear in a space which is closer to outside ambient. The temperature difference is your enemy. At home this can be easy - I just keep my gear in a room with a dehumidifier (when needed), and open window (when weather allows), and a ceiling fan. When traveling, sometimes a little harder as less control or options. Regardless, if you go outside and your lens is always fogging strongly, your at-risk.

You should get the electronic dry cabinet instead of a dehumidifier. Much more efficient and your gear will be dry all the time when not in use.

Same as others said - put the gear in the car ahead of time to let it adjust.  The quick snap from ice cold to hot & humid will cause condensation which in turn wreaks havoc.

FL is a miserable place to be for 7+ months a year.  The other times it can be stupid windy, or cold - or all kinds of other things with an occasional nice day, between being hit by lightning and hurricanes.    Yet some people call it paradise.     YMMV

The science and solution is very simple. If an object (camera, lens, flash for example) is below the dew point temperature of the air,  condensation will occur and form on it. This often occurs when the equipment goes from an air conditioned environment to a warmer humid one (inside to outside). I simply raise the equipment temperature to above the outside dew point by warming it with a portable hand held hair dryer. Just carefully warm up the equipment to the outside temperature or even a bit above. Now when you take the equipment outside no condensation will form on it. If you are not going to use it for a while such as driving to a photo location, simply transport it in an insulated "cooler" which will help maintain it at the warmer temperature. I keep this in my car trunk (non-air conditioned). This completely solves the condensation problem that occurs when going from a colder air conditioned environment to a warmer humid outside temperature.

Oh, I've also been known to take the hair dryer with me when entering a butterfly enclosure (similar to a greenhouse) and immediately going to a nearby electrical outlet, plugging in my hairdryer, opening my camera bag/backpack and warming up my equipment to prevent condensation on it.

For the "opposite" situation...shooting in winter outside in a cold environment and coming inside to a much warmer one simply put your equipment (can even stay in your camera bag) into a plastic bag and seal it prior to going inside. Then take it inside and leave it alone until it reaches the inside temperature. At that point condensation cannot occur (above the inside dew point temperature).

Finally, if your inside conditions are high humidity which mold enjoys simply store your equipment in a closed low humidity case using indicating silica gel packs. They absorb moisture and change color to let you know when they have to be regenerated (moisture removal) through heating.

Re: Florida’s humidity

One correction. I should have stated "at or below" the dew point vs. "below" the dew point.

I live in Florida and when I read this thread - I bought a bunch of silica gel packs but later forgot the advice offered here as I never experienced a problem

Until yesterday

I was on "photographing the grandchildren duty" before the fireworks  -- when the lens fogged up instantaneously.

No time last night to wait for the camera to warm up so will have to try again today.

Yep - it's a common thing in Florida - my cameras and lenses have regularly gotten fogged from condensation when transferring between AC interiors and massively humid and hot exteriors.

All of the advice offered is good, common practice - though you still are likely to run into some condensation issues at some times.  I use gel packs in storage, I try to put camera gear in a car trunk or in a window to start acclimatizing before I need to shoot, and so on.

But sometimes, you'll still get fogged lenses.  The problems don't necessarily happen because the lenses or cameras condensate or fog - the problems can occur when you turn them on and try to shoot with them in that condition.  If you find the camera/lens fogged inside, don't start shooting or turn it on - let the sun and heat dry it first - point the lens into the sun with the cover off, let the camera sit for a bit outside...once it all burns off, THEN you can turn it on and begin shooting.  Follow that simple step, and you shouldn't have any issues.  I've shot with a dozen+ cameras here in Florida, and throughout the Caribbean, in those conditions and encountered fogged up lenses and condensation dozens of times despite all the precautions and steps taken - still haven't ever had a camera or lens failure or issue with mold, etc by just always letting the condensation and fog burn off and dry up before trying to shoot with it.

I have been going to Florida for over 30 years , usually in the months of  January and Feb and I agree with you about the changing weather.  One year can be  just over 50 degrees and the next year 80 degrees. I don't usually have any problems with my camera or lenses, but I do what others say. I put the camera in the car a few hours before I am ready to go with the windows slightly down and no air.
