Fantasea G Series BigEye Lens User Manual
Field of View on Land
1. Introduction
The Fantasea BigEye Lens G Series is a patented “wet” accessory wide angle lens that was especially
designed for Canon G Series underwater camera housings. The lens fits onto the housing lens port and can
be installed and removed during the course of the dive. It is perfect for photographing seascapes, divers,
ship wrecks and schools of fish without moving further away from the subject, thereby still taking full
advantage of water clarity and artificial light sources.
2. Technology
The BigEye Lens G Series makes use of a new patented lens technology, which allows for high quality
underwater wide angle images free of distortions. The new technology uses air instead of glass as an optical
element and enables recovering 100% of the camera lens optical properties that would normally be lost
underwater. The air pocket inside the lens enhances the angle of light refraction, thereby restoring the
original angle of coverage of the camera lens (see figures below). This patented technology was especially
designed for underwater photography and therefore the lens should only be used when the system is
submerged in water.
