The Circular Fisheye Converter provides a circular fisheye perspective when the camera is set to 24mm, and diagonal fisheye capabilities when the camera is zoomed. The resulting image quality is spectacular- comparable to a Canon or Nikon 8-15mm Fisheye lens on a full-frame DSLR body. It's the perfect combination for ultra-wide-angle, close-focus wide-angle, and over-under underwater photography.
The good news is that you aren't limited to a fisheye or ultra-wide-angle perspective. The camera may be zoomed while the lens is attached and can focus up to a 30mm macro equivalent underwater.

The optical grade acrylic dome provides super sharp and bright imaging while being lightweight for handling and travel.
The dome port replaces the standard flat port on the housing. Simply unthread the standard flat port and thread in the dome port. We recommend a rubber strap wrench commonly available at your local hardware store or as product # 0945.01 (not included). The included dome shade reduces reflections, protects the dome, and allows you to set the housing down on its face for easy assembly and disassembly.
This dome port cannot be removed and replaced underwater. The dome port may be used with or without a lens attached. Without the lens attached some reflections may be present when shooting towards a bright light source (like the sun).
