I was scuba diving in Indonesia in 2008 at a resort called Wakatobi Dive Resort. Back then I was using a D70S, my very first digital camera, for underwater photography. The housing for that camera can be seen in a gallery at pbase (the link is in my signature). Anyway, I hadn't assembled the camera, lens, housing & strobes correctly so it flooded soon after I entered the water. My D70S as well as my 105 macro lens were both fried, having been exposed to salt water, a medium not friendly to electronics 😱
Fortunately, I had brought along a backup camera, a D70, and I'd insured all of my underwater photography equipmentg before the trip. I ended up using my backup D70 the rest of the trip and was reimbursed for the fried camera and lens after filing a claim when I got back home. So, it didn't turn out too badly except that I didn't have the use of my 105 lens the rest of the trip and had to use my 60 macro lens instead.
