AFAIK, this "fog problem" is mostly related to the environments in which the drone is operated... When a lens is brought from a cold environment to a hot environment with high humidity, then it sometimes gets this kind of condensation phenomena when the conditions are right. A zoom lens needs to move, and even fixed focal length lenses need to move some lens elements to adjust focus, and thus air gets sucked in from the outside. I think the Mini 2 does not suffer as badly as its sensor is much smaller, and thus there is not as much need to adjust focus by moving the lens elements.
This kind of issues are pretty much not covered by the warranty. For example, people get this kind of condensation phenomena with their iPhones, DSLR lenses, and all they can do is to ship their equipment for service.
I am a professional photographer, I have several lenses that I used while living in Siberia. I did some shooting in the winter on my Nikon D610 and D810. The temperature at home or in the car was approxiametely +20 Celsius, the temperature outside below -20 Celsius, and then the condensate is justified, and I used the equipment carefully. But not a single lens got wet inside it!!! This is not normal! I still using one of them Sgima 35mm and no problem!
Now I live in Bali, and I use the drone here. The temperature alllways is approxiametely +30 degrees Celsius, at my room +25 maybe. there is not even enough difference for condensation to fog! I agree that the humidity is high, but it is acceptable for a drone. Before that, I had a "Mini 2" and I even flew next to the waterfalls and did not experience any problems. And then I buy "Mini 3 Pro" and maybe after 10 flights, lens began to sweat from the inside! I gave it to the service first time, waited two weeks, they just wiped the lens, without changing anything. On second flight I again saw fog inside the lens. I demanded to replace my drone, but they told me that they could only replace the camera. I waited 5 weeks! And what do you think happened? On third flight the fog was again in lens! I now demand to replace my entire drone, I don’t know what could be the reason, maybe it heats up somewhere more than necessary, maybe something else, but I can’t use it!
I will now wait another month for service to change it for me, and I will not be surprised if they just replace the camera again, because official DJI support cannot affect the decisions of the service in Indonesia. Excellent service!
The most interesting thing is that in the store where I bought the drone, the employees are surprised at my problem, they say that they sold a lot of drones, but they didn’t come to them with such a problem, that is, people use "Mini 3 Pro" here in Bali, but they saw my problem, I with them it took off and showed the result of lens fogging. |
