Ikelite DS51 II 50Ws Underwater TTL Strobe

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.

Ergonomics
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.

Ture TTL Expoure
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. Our 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.
