I went up to the Mississippi headwaters this weekend and fell in with my Nikon FA3 lens attached to a Nikon EM body. I thought it was fine but then, to my horror, discovered that water had somehow gotten into the lens. It appears to be between the front (outside) lens and the lens that faces the inside of the camera which causes a fog like condition. Is it worth repairing? Can I repair it myself? Should I just write it off and purchase a new (used) Nikon lens? Note: at the time of the accident, I was using a Nikon EM body. Now the shutter sticks on that body and I am wondering what to do about that. But my primary concern is the lens, since I use it on my "good" Nikon (the FA3). Any advise would be much appreciated.
