Pictures taken with a C-5050 with a wide angle lens with a dome port and two external DS 125 strobes set to 1/2 power using manual focus set to 31".

The beauty of these settings is that there is virtually no shutter lag AND no focusing light is needed for night dives or dark engine room shots.

Manual Mode F 5.60 S 1/60 with fixed focus distance of 31"
