Are there any specific filters, lenses, etc built for the Olympus underwater housing (PT-030)? I am looking on-line and have met with limited success. I have found lenses and such for surface use, but nothing specific on underwater use.
I am looking at buying a delicately used SP-350 with housing from a friend that upgraded to the Nikon D70 so I am hoping he gives me a sweet deal. I am trying to do some research on options beforehand though.
Thank you.
