I found keeping the ISO on auto, for the change of light that occurs when descending and ascending, is the most efficient way of dealing with the changing light. Also as there is no way of manually focusing while underwater, so keeping the auto focus on and using the auto focus button seemed the best way. When set up and finally underwater, the housing works quite well. Moving around with it isn’t too much of a struggle even with the dive weights hanging below. The record button and auto focus button is easy enough to use and makes life easy when filming. When filming, panning and moving forward and backwards isn’t too difficult, but when is comes to tilting, it is almost impossible to get a decent tilt. The air, which sits in the top of the housing, makes it difficult to tilt the camera up and down, so the movement you can produce with the housing is limited.
The ewa-marine is perfect, being priced at around £300, for underwater photography and some filming, but with the design limiting movement and overall camera use underwater, it isn’t quite right for professional film making.
