Francisco from Azores mid Atlantic,
Scuba diver from child like to make video-sub (Sony HD) and now underwater photo. Have an old D70 on a CD70 Sealux housing (Z240 + Sea&Sea YS50) and canon G11 on canon plexiglass housing (Ikelite A35). I have a lot to learn with you about photo-sub and hope you will help on that desire.
Sincerely
Francisco
