Ikelite underwaterhousing for EOS 250D / Rebel SL3

This powerful compact housing includes all of Ikelites latest upgrades to controls and ergonomics. The shutter lever has been updated to a more sensitive and natural feeling curved design. Soft-touch control knobs add comfort and extra grip to the most commonly used functions. Stainless steel, direct-drive rotating controls are virtually fail-safe and user serviceable and adjustable in a pinch.

All rear camera buttons are accessible by smooth action, hard anodized aluminum push buttons for reliable performance and easy maintenance. These controls are clearly labeled by laser engraving on the back of the housing that never fades or falls off.

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. 

Set Up

The camera mount is front-loading for easy installation and removal. A small mounting plate attaches to the bottom of the camera and secures in the front of the housing. The camera mounting plate does not need to be removed from the camera for surface use or when changing the battery or memory cards. The mounting plate features a 1/4-20 threaded mount on the bottom so that it can be attached to a tripod on the surface.

Confidence

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.

Vacuum Testing

A spare 1/2-20 threaded accessory port is provided on the side of the housing for easily installation of the optional vacuum kit.  A vacuum kit allows you to draw a vacuum on the housing to check for proper assembly prior to entering the water. Drawing a vacuum on the system also provides extra security at the surface of the water, especially important when using the housing in rough surf.

True TTL exposure

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. For the best results, we recommend adding an external flash or high-powered constant-on light if you'll be diving regularly below 15' (3m).

An integrated TTL circuit is fine-tuned to the Canon EOS 250D Rebel SL3 flash exposure protocol for the most accurate exposure possible. The circuit is powered by the strobe for zero maintenance and no batteries to change. Exposure compensation in TTL mode is supported using the camera's built-in control. The TTL system can be used with current model Ikelite DS series strobes. Refer to the Strobe Compatibility section for serial number requirements.

This housing provides a direct electrical connection to the camera's external flash hot shoe. Cord attachment is as easy as screwing in a light bulb, and the threaded fit prevents accidental detachment during use. 

Changes to Canon's flash hotshoe prevent the electrical connection of manual strobes. SEA&SEA, INON, Nikonos, and strobes by other manufacturers are not compatible with this system.

The built-in flash is not usable in this installation. Triggering of fiber optic strobes is not supported at this time. A strobe must be connected by electrical sync cord.

Port System

It couldn't be more simple to change ports than this system—just press the port on and tighten three thumb screws. Feel positive reinforcement that the port is secure with simple parts you can trust in a remote location.

This housing accepts ports from our DLM Port System to accommodate a selection of the best zoom, macro, and wide angle lenses for underwater use. Our custom optical grade acrylic domes components provide the color, clarity, and durability of glass at a fraction of the travel weight and cost.

The included Dome Port with Zoom #5516.15 and Zoom Gear #5515.11 allow zoom operation with the kit lens Canon EF-S 18-55mm f/4-5.6 STM. The port and zoom gear are interchangeable for use with other lenses. Refer to the port chart for complete compatibility information.
