Video Camera Underwater Housing
What is the best platform for a Viewfinder of the camera under the water and controls?
I'm using a tight army surplus ammo case with a plexiglass window presented as an Underwater Camera housing for underwater videos. Anyone recommend a Good Camera for under 500 with the ability to connect a wired controller or Lanc? any other idea of this project?
I do not know specifically. Both bhphoto.com adorama.com and take some underwater housings and equipment. You may want to check your sites in a compatible combination.
