Features
- Function and ergonomics - This housing is designed and built in the USA by experienced divers who are committed to providing top quality and value. Large, easy-to-reach controls are provided for all camera functions except the Flash pop-up switch. If using an external underwater strobe, simply open the flash prior to installation of the camera in the housing. A drop-in, front-loading camera mounting system makes set-up and break down a breeze. An ergonomic side-mounted shutter lever is comfortable and reduces fatigue. The camera's full 25-625mm equivalent zoom range is usable in the housing without vignetting.
- Zoom and macro close-up - The optional WD-4 Wide Angle Dome # 6430.4 provides a wider angle of view underwater without the edge distortion, heaviness, or difficult attachment typically associated with an external wide angle wet lens. The WD-4 is a 0.75x magnification factor and simply slides on and off of the housing's lens port. A press-fit Macro Adapter # 9306.78 is available for the attachment of 67mm threaded accessory macro lenses. We recommend a macro lens which is designed for underwater use like those from Epoque, INON, Subsee, Nauticam, and other manufacturers. The adapter should not be used with 67mm threaded wide angle lenses. The wide angle lens would be too far away from the camera's lens to provide an improved image.
- Accessory mounting - Two 1/4-20 threaded mounting points are included on the bottom of the housing for the rotation-free attachment of a tray and handle system. Handles provide improved ergonomics underwater and are the foundation for your lighting mounts. Mounting lights on a side arm rather than directly over the camera's lens helps to reduce the appearance of backscatter which looks like snow in your underwater images. Light is absorbed as it travels through even short distances underwater, making colors appear dull or monochromatic. To preserve the natural colors of your subject, it's important to stay within arm's reach—no more than 3-4 feet (1m) away. There is a simple rule that brighter is better underwater. A high-quality lighting system can produce magazine quality results with almost any compact camera system.
- Color correcting filters - Enhanced color correction and clarity can be achieved by adding a color filter or external light. The lens port of the housing accepts our 3.9" diameter color filters, which are available for both tropical blue water and green water settings. A color filter reduces the amount of light that reaches the camera's sensor, so they are most effective in sunny conditions up to about 45 feet (15m). The absolute maximum effectiveness is 80 feet (24m) in ideal conditions of full sun and visibility of 100+ feet (30+m).
- Flash and constant on lights - A flash or constant on light is necessary for close-up, night dives, and deep depths. An external light also brings out more colors in sunny conditions. External lights are typically not used in conjunction with color filters, as the combination will result in tones that are too red or too purple. The location of the camera's flash in relation to the lens makes it unusable for lighting your subject underwater. However, the camera's flash may be used to trigger an external strobe. Two ports are provided for the connection of up to two fiber optically triggered underwater strobes. Alternatively, a bright constant-on video light can be used. A constant-on light is not as bright as a strobe flash. Constant-on lights do provide added versatility because they can be used for focus assist and for improved colors when shooting video.
- Durability and corrosion free performance - Our ABS-PC blend provides strength and corrosion free performance year after year with minimal maintenance. The specially formulated color deflects the sun to keep your camera running cooler, longer. Ikelite products are designed, built and tested in the USA. We use locally sourced, top-grade materials. Our housings are built by hand and individually tested for fit and function. Every unit is water pressure tested to 200 feet (60m). We back our products with over 50 years of experience and the best reputation for service within the dive industry.
- Compatibility - Differences in lens and control placement prevent cameras other than the Canon PowerShot SX620 HS from being used in this housing. We are not aware of any other camera models which may be used in or adapted to this particular housing.
