Capture beautiful over-under shots and underwater content with this SeaPal 6" Dome mounted on your JOBY SeaPal Waterproof Case for smartphones. The optically correct acrylic dome is ideal for half-in/half-out shots at the surface and general photos and video below, including close-focus wide-angle techniques. The dome can accommodate smartphone camera lenses. When using ultra-wide lenses on some phones, you may experience a little vignetting, but zooming in slightly will correct it.
