I have a Olympus C-2100 and the only lens you can get for it is a 1.7x Tele Conversion lens. I took tiff pictures and zoomed in as best I could. I am sure that it is possible to get better pictures. I hope to upgrade my camera before the Alaska trip next year.
I could see each reef light with my own eyes well enough to see the shape and be certain of the identification. Not a small feat with my eyes. I had to get a special prescription snorkel mask this evening to go snorkeling at Sand Key tomorrow. I will have close ups of that one! I wish I had time to get closer to Fowey Rocks. but you can't do everything.
