Some Ikelite video housings support the use of the Raynox DCR-730 wide-angle conversion lens. This lens is 0.7x conversion, which provides 37% more area of coverage. High-index optical glass elements provide 375 lines/mm resolution power at center.
Please Note: Most cameras require an accessory step-up or step-down adapter ring for the attachment of this lens. Refer to the appropriate housing webpage for more information. Raynox lenses and adapter rings referenced are not made by or supplied by Ikelite.
Use of these internal lenses requires replacement of the housing's standard front lens port with a longer accessory port. Accessory ports are available in both dome and flat versions.
Larger Diameter Ports for select models. Look for "Raynox #3" in the W/A Lens Option column of the Sizes and Features Chart to determine whether the following ports are compatible with your housing.
The #9306 Optional Dome Port provides increased angle of coverage and improved clarity, but limits zoom and macro range.
The #9306.1 Optional Flat Port offers zoom and macro capabilities but reduces the overall conversion factor of the lens.
These ports accept 3.9" Color Filters #6441.46 for Tropical Blue Water and #6441.86 for Green Water.
