Help, please! Yesterday, the kit telephoto lens (75-200) from my new Sony Alpha-100 fell into the ocean while I was photographing some boats. It sat in salt water for about 12 hours before the tide went out and I could find it. I immediately put it into isopropyl alcohol, hoping the alcohol would extract the water (it's a trick I use in woodturning to dry out wet wood).
I removed the UV filter from the front, and tried moving the mechanisms. A narrow, black felt band that was behind the focusing ring fell out -- it had been held in place with glue, which failed.
The lens is full of water/alcohol. What do I do next? I am relatively comfortable with optical systems (I used a microscope in my day job as a pathologist), but I'm not sure how hard it is to dismantle and repair a lens.
Thanks so much for your advice.
