Ikelite: How To Assemble a Complete Underwater Camera System 

Ikelite 200DLM/C Underwater TTL Housing for Canon EOS 200D Rebel SL2 DSLR

The Canon EOS 200D Rebel SL2 is a welcome upgrade to the hugely popular EOS 100D Rebel SL1 Compact DSLR Camera. What makes this system so different from mirrorless and even other DSLR systems? The fact that the camera body is compact and lightweight, ergonomically shaped like a DSLR, and capable of accepting Canon EF mount lenses.

Whether you've been shooting a full-frame DSLR or a compact point-and-shoot, the EOS 200D Rebel SL2 may be the best next step. This system combines fast focus, 24-megapixel resolution, TTL exposure, and great battery life into a housing that's half the size and weight of all other DSLR models.

Ergonomics and handling

This powerful compact housing includes all of Ikelite's latest upgrades to controls and ergonomics. The shutter lever has been updated to a more sensitive and natural feeling curved design. The standard control hugs the side of the housing for comfortable use when hand holding. It can be easily extended using the optional Shutter Trigger Extension # 4077.93 to put it within easy reach when using a right-hand quick release handle.

New soft-touch control knobs add comfort and extra grip to the most commonly used functions. Ikelite's push buttons have been redesigned to reduce weight and salt build-up. The back of the housing features laser engraved control symbols which will never fade or fall off.

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. Ikelite has 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.

A spare 1/2-20 threaded accessory port is provided on the side of the housing for easy installation of the optional Vacuum Kit # 47012. A vacuum kit allows you to pressurize the housing to check for proper assembly prior to entering the water.

Viewfinders

The included Supereye Viewfinder provides an enhanced view of the camera's optical viewfinder when viewed through a dive mask. The viewfinder removes quickly and easily for the attachment of an optional Straight Magnified Viewfinder # 6890 or 45° Magnified Viewfinder (Type 1) # 6891.1.

The camera's large, super-bright LCD screen is viewable edge-to-edge through the back of the housing.

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, Ikelite recommends 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 200D Rebel SL2 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.

SEA&SEA, INON, and Nikonos strobes are not capable of powering the circuitry. SEA&SEA, INON, and Nikonos strobes will still enjoy fast recycle times and improved battery life but must be used in manual exposure modes only.

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. The bulkhead connection has been moved to the top of the housing to keep cords out of your way and reduce strain on the cord ends. A variety of sync cord terminations are available for Ikelite, SEA&SEA, INON, or Nikonos strobes for ultimate versatility.

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 an electrical sync cord.

A bright constant-on video light can be used instead of or in addition to a flash. 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.

There is a simple rule that brighter is better underwater. A high-quality lighting system can produce magazine-quality results with almost any camera system.

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. The Tray with Dual Quick Release Handles # 9523.64 is the most popular choice for both handling and attachment of accessories. Ikelite recommends installing the Shutter Trigger Extension # 4077.93 when using a right-hand handle.

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 Ikelite's DLM Port System to accommodate a selection of the best zoom, macro, and wide angle lenses for underwater use. Ikelite's custom optical grade acrylic domes components provide the color, clarity, and durability of glass at a fraction of the travel weight and cost.

Durability and corrosion free performance

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