Here's a short/rough video compilation from the Canon 5D Mark III in Nauticam housing.
Wide angle with Canon 8-15mm FE (w/ Magic filter, Manual WB) behind S&S glass dome port (with 30mm ext ring), Natural light.
Macro with Canon 100mm L IS, Subsee +5/10, Sola 1200 lights, Xit 404 tripod, SmallHD DP4 monitor.
Setting was 1080/30p, 1/60sec with various f numbers and ISO range from 100 to 1600, no color grading or noise reduction in post editing.
I could not include many footage which can showing iso capability of 5dmk3 (footage for my client) but camera produce very usable footage till' iso 1600 and can go to 3200/6400 in tought situations.
