Ikelite Canon SX730 and SX740 HS Underwater Housing

Ikelite Housing for Canon PowerShot SX730 HS and SX740 HS

This compact and lightweight housing allows you to operate either camera up to depths of 200 feet (60m). It is designed and built in the USA by experienced divers with a commitment to providing top quality and value.

Large, easy-to-reach controls are provided for all camera functions except the Flash open lever. If using an external underwater strobe, simply open the flash prior to installation of the camera in the housing. 

Rear controls are marked with easy-to-see laser engraved symbols which never fade or fall off. The front-loading camera mounting system makes installation and removal a breeze. The camera mounting plate allows ready access to the battery and memory card, and features a standard 1/4-20 mounting point for attachment to a tripod topside.

Zoom and macro close-up

The optional WD-4 Wide Angle Dome provides a wider angle of view underwater without the edge distortion, vignetting, or weight typically associated with an external wide angle 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 (sold separately) 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 Saga, 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.

Color correction and external lighting

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.

Additional color correction and clarity can be obtained by adding a color filter or external light. The lens port of the housing accept our 3.9-inch 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 approximately 80 feet (24m).

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.

Two 1/4-20 threaded mounting points are included on the bottom of the housing for the attachment of a tray and handle system. Handles provide improved ergonomics underwater and are the foundation for your lighting mounts.

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.

Durability and corrosion free performance

The unique rear seal design prevents accidental twisting or stretching of the o-ring for simple and confident assembly. We have eliminated the need for an o-ring groove or channel which can trap sand, dirt, or debris. Two double-passivated stainless steel locking lid snaps are simple to use and virtually unbreakable. The clear back allows you to see the o-ring form a solid, watertight seal as it closes.
