Condensation in the camera

[rod goslin]

Taking my mavic pro out for a spin, after a long lay off ( The UK summer has not been that good, whatever the weather men insist), I was a bit disconcerted to find the returns from the camera were extremely blurred. It was rather like being in a thick fog, rather than a sunny morning. Looking at the camera lense, with a magnifier,an area of condensation exactly centred of the lens proper, covered the inside of the glass lens cover. Turning all off the condensation disappeared, but on switching on again, it soon reformed . Even warming the whole of the drone, did not work. As soon as it was up in the air , the fog returned. Why the camera should have become damp is a puzzle. All the kit is kept in a room in the house and dry. Has anyone any idea How the get the damp out of the camera, and a reason why the condensation collected exactly where it would have the maximum disruption, would be welcome

Hi Rod - loads of threads here with regards to lens fogging up. Not much you can do really except change the lens - you can get them @ Amazon. I ( along with loads more folks ) tried taking off the lens barrel which is where it contains the moisture & putting it with silica gel / or in a bag of dried rice but it really doesn't solve the issue. Some guys swear that putting it in the sun will get rid of the fogging but as you take off it fogs right back up.
I keep my Mavic in a dry atmosphere/environment as I live in the tropics but flying on a vacation trip to Scotland last year in foggy weather seemed to have led to the fogging.
I ended up buying a new camera lens & it solved the problem
Good luck

I wouldn’t bother with rice, all you’ll do is introduce dust. Fresh or freshly dried silica gel is what is needed. Best to use is indicating silica gel. A colour change shows when it’s wet and you can dry it out in a warm electric oven.
Best way to combat moisture is constant use and a few precautions. Try to let the drone cool down after use in a dry atmosphere, inside a sealed bag with dry silica gel would be best. The same when moving between temperatures, ie. from warm to cold and cold to warm. Seal in a bag until the drone is the same temperature as it’s surroundings.

Condensation in my lens

My 2 month old Mavic Pro appears to develop a wee bit of condensation inside and on the lens which causes it to have trouble judging the light. It isn't always there and it goes away on its own. Any thoughts on cause and solution?

Mavic Pro Camera Condensation

I tried to fly the mavic today for the first time in about 2 weeks and after turning it on I noticed that there's condensation inside the camera that looks similar to this: Just a spot right in the middle of the camera. When I turn the drone off it goes away quickly, but every time I turn it...

Condensation inside lens

I've been using my mavic pro in Hawaii for several months. Now, without me having changed how I store the drone or where I fly it, every time I try to fly it condensation quickly forms inside the lens, making the camera unusable for video or photos. Also, the icon for going to the intelligent...

Condensation on the lens.

Guys I have had my Mavic for about 2 weeks now and loving it. Last night it was our last home football game of the year. It was between 40 and 50 degrees. I put the Mavic up about 5 minutes into the flight the lens had some condensation light fog on it. I put it up today for a few minutes...

Lens Condensation when flying

For the first time I'm having lens condensation problems. I'm on holiday in hot dry Spain. I live in hot humid Indonesia, where I haven't had any problems. I've left the Mavic outside to make sure the temp is good. All is fine. As soon as I take off I get a little blob of condensation right in...

Fog / condensation appearing inside lens during flight

Ive had my drone for a few months and only had it in the air a few times. During the last 2 flights the lens has been getting covered with fog / condensation after about 5 /10 mins in the air which is ruining the footage and is unusable. On both occasions it has been quite cold outside, but...

Condensation inside lens ?

Just watched a youtube review. Said he had condensation on inside of lens, seems odd, never had that with any other drone.

Mavic Lens has condensation - how to replace?

My lens has water moisture in it and I cannot get a new one from DJI where they say it costs $101. I just need the front part of the camera, none of the rear parts if anyone has advice on where to get new one or decent second hand please let me know. DJI has the worst service ever!

For the moment, I've sealed the whole thing inside a poly bag with a re-vitalised silica gel drying canister. I'll give it a day or so inside the bag, then try again. It's odd that the condensation only appears when the Mavic is powered on, and vanishes when the power is turned off. Perhaps something in the camera warms up, driving the moisture out to condense on the glass immediately in front of the lens assembly. Pity there seems no way of removing the cover glass to allow the damp to get out.

Before I ended up changing the lens I did actually break the glass with a center punch but unfortunately dust from the broken glass got inside the sensor & although in theory it worked (as I have filters to cover the open lens) in practice if I were to do it again I would take the lens off & tap the glass with the lens facing DOWN! carefully take the glass away & use an ND filter.
Hope it doesn't come to that & the condensation clears for you - I still don't understand how the lens gets moisture in it in the 1st place because that little sucka is a real ***** to get off & seems pretty well sealed against the elements!

The dessicant can seems to have worked. Taking it out for the local circuit, no fogginess was seen.I'll order a couple of dessicant packs, from Amazon and slip one into the Mavic's carry case. I suppose it's the change of barometric pressure when ascending and descending that drives damp air into the camera. Later there's no real change in pressure, so the damp tends to stay inside.. It's a bit of a relief that it's something fairly simple. I was getting worried about camera problems, and cost

Cheers

Great, glad that worked. Don’t forget to reactivate (dry) the silica gel regularly. Even in a sealed container it can absorb enough moisture to stop working.
