Ikelite: How To Assemble a Complete Underwater Camera System

Ikelite DS51 II 50Ws TTL Underwater Strobe

Light is the most important thing you can add to improve your underwater photos. The second most important thing is the right amount of light.

Travel Ready

If size and weight are your primary deciding factors, the DS51 II is for you. The DS51 II is one of the smallest and lightest strobes in its class weighing in at less than one pound (443g) per strobe. The compact size makes it simple to position the strobe for macro, super macro, and close focus wide angle.
 

Egonomics

You won't need a pair of tweezers to set the DS51 strobe. The strobe power/exposure mode switch is prominent on the rear of the strobe with a bright white detail makes it easy to see where it's pointing.

When used in TTL mode together with a compatible TTL converter, your camera will meter the scene and adjust strobe power automatically.
 

True TTL Exposure

TTL flash exposure takes advantage of your camera's sophisticated light metering system to automatically adjust flash output. In TTL flash mode the camera triggers a pre-flash - before the image is captured - and uses information it receives back to adjust output in time for the photo. Ikelite's line of proprietary TTL converters translates this signal for correct flash exposure underwater with Ikelite DS strobes. Simply leave the strobe in the TTL setting and focus on composition and camera exposure settings.

The advantages of TTL metering are far greater than simply variable flash output. TTL improves recycle time, enables burst shooting, and saves battery life of both your camera and your strobe. TTL is critical when shooting fast-moving subjects both large and small.
 

Mix and Match

Most shooters choose a one or two DS51 II strobes for macro and dual DS51 II strobes for wide angle. Combining the DS51 with brighter strobes like the DS160 II, DS162, or DS230, can also add depth and contrast to your images. Attach the less powerful strobe as a secondary when mixing strobes of different intensity.

The DS51 II can also be used remotely by combining with the Optical Slave Converter and a 1 ft Extension Cord. The Optical Slave Converter triggers the strobe off a primary flash for interesting lighting effects in pool studios, caves, wrecks, and other interesting applications.
 

The Proven Leader in Underwater Lighting

Ikelite was the first to introduce these underwater strobe technologies which are considered standard today: aiming lights, interchangeable cords, removable battery packs, smart charging, battery power indicators, wireless TTL slave sensors, built-in video lights, and TTL communication with digital cameras.

Ikelite has the longest track record in the design and manufacture of professional strobe lighting for underwater use. Ikelite offers the only underwater strobes designed and manufactured in the USA and distributed worldwide to over 95 countries.
