The FCON-T02 Circular Fisheye Converter (not included) 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 in coverage 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 optical grade acrylic dome provides super sharp and bright imaging while being lightweight for handling and travel.

This dome port cannot be removed and replaced underwater. The dome port may be used with or without lens attached. Without the lens attached some reflections may be present when shooting towards a bright light source (like the sun).

This housing does not support the use of the FCON-T01 Fisheye Lens which is too large in diameter to fit in the opening of the lens port.

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 dome port precludes the attachment of external lenses or color filters. This housing is not compatible with the FCON-T01 Fisheye Lens.
