If it would be my bird i toke apart everything that can be taken apart as far as possible. Pls double check as latent condensation will cause issue's in the future.
The bird itself I believe is fine. There were only a couple of drops of water inside the shell, there is nowhere for moisture to be trapped. What happened with the lens is somewhat unique to the optics. If you are already familiar with what I am about to say I apologize:
The lens is dual element design mounted within an aluminum tube. The tube is threaded at either end. The threads at the inner lens allow for adjusting focus. Once focused, DJI glues the barrel to the base to lock in the setting. My base was glued all the way around, so it is unlikely water was able to enter the lens assembly from that end. The camera itself was completely dry inside.
The forward lens is secured in place with a cap (or it is mounted to the cap). I assume the cap threads onto the lens barrel? There were four spots of glue at 90 degrees securing the cap in place. The forward end was only partially sealed, and I believe moisture seeped into the lens assembly through the small gaps where the forward lens retainer was left unglued. It would take only a minute bit of water to enter to cause condensation on the small forward lens, and it would be difficult for that moisture to escape from within the confines of the nearly-sealed lens barrel.
When I first applied heat, the condensation would vanish as soon as the lens became warm. Within moments of removing the heat, however, the condensation would reappear. Ultimately I let the dryer warm the lens for about 30 minutes on low heat, rotating the lens every few minutes. At the end, condensation no longer appeared and the moisture must have found its way out of the semi-sealed lens assembly.
