In May I dropped my GX7 and 100-300mm in a saltwater lagoon in Costa Rica. After drying them for a few days they both appeared to be toast. I brought them back and put them away. I was looking in the storage today and noticed them. The lens had lots of salt deposits inside and did not work. I put a fresh battery in the camera and it fired right up. I had to go through set up like it was a new camera but everything appears to work. This is not the first time this has happened to me I had a G5 lost in a house flood that also returned to life but that was fresh water.
