Ikelite Underwater Housing Canon SX730 HS, SX740 HS


Ikelite 6148.73 Housing for Canon PowerShot SX730 HS, SX740 HS

Product Details

A full-featured and durable underwater housing from Ikelite for the Canon PowerShot SX730 HS cameras. Suitable for scuba, snorkel, surf, pool, and any application in or around the water.

The zoom range of this camera is limited while inside of the housing in order to provide the best underwater imaging possible. The camera cannot be zoomed beyond 220mm equivalent inside of the housing.

The PowerShot SX730 HS is a favourite camera for travel because of its compact size and extended, optically stabilized 40x zoom lens. A large 20.3MP BSI-CMOS sensor and 1080/60p video capture mean plenty of resolution for sharp images suitable for framing.

This compact and lightweight housing allow you to operate your Canon PowerShot SX730 HS camera up to depths of 60m (200 feet). 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 Ikelite WD-4 Wide Angle Dome provides a wider angle of view underwater without the edge distortion, heaviness or difficult attachment typically associated with an external wide-angle lens. The WD-4 is a 0.75x magnification factor and simply slides on and off the housing’s lens port.

A press-fit Macro Adapter is available for the attachment of 67mm threaded accessory macro lenses. Ikelite recommends a macro lens that is designed for underwater use like those from AOI, INON, I-Dive, Aquatica, 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.

Colour correction and external lighting

Light is absorbed as it travels through even short distances underwater, making colours appear dull or monochromatic. To preserve the natural colours of your subject, it’s important to stay within arm’s reach—no more than 1m (3-4 feet) away.

Additional colour correction and clarity can be obtained by adding a colour filter or external light. The lens port of the housing accepts Ikelite’s 3.9-inch diameter colour filters, which are available for both tropical blue water and green water settings. A colour filter reduces the amount of light that reaches the camera’s sensor, so they are most effective in sunny conditions up to approximately 24m (80 feet).

A flash or constant-on light is necessary for close-up, night dives, and deep depths. An external light also brings out more colours in sunny conditions. External lights are typically not used in conjunction with colour 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 fibre 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 colours 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.

Vacuum Testing

A spare 1/2-20 threaded Accessory Port on the side of the housing is the perfect location for the installation of an optional vacuum valve. Vacuum Kit # 47012 allows you to pressurize the housing to check for leaks prior to entering the water.

Durability and corrosion-free performance

Ikelite’s ABS-PC blend provides strength and corrosion-free performance year after year with minimal maintenance. The specially formulated colour deflects the sun to keep your camera running cooler, longer. Compared to black or clear housings, the light grey colour provides superior contrast for an enhanced view of the camera, LCD screen, and O-ring seal.

The unique rear seal design prevents accidental twisting or stretching of the O-ring for simple and confident assembly. Ikelite 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.

Ikelite products are designed, built and tested in the USA. They use locally sourced, top-grade materials. Ikelite’s housings are built by hand and individually tested for fit and function. Every unit is water pressure tested to 60m (200 feet). Ikelite back their products with over 50 years of experience and the best reputation for service within the dive industry.
