TRT TTL O-Turtle 2 Smart+ TTL Flash Trigger for OM System, Olympus, & Panasonic Cameras

A reliable TTL and Manual trigger that works via fiber optic cable or sync cord, and due to its LED technology, the battery of your camera lasts longer.

o-TURTLE 2 RC SMART+ underwater photo trigger for Olympus and Panasonic camera models

This underwater TTL trigger was developed for Olympus and Panasonic mirrorless camera systems. The new o-TURTLE 2 RC SMART + TTL trigger works in Manual or TTL mode, which you can change during dive. The o-TURTLE 2 RC SMART+ underwater flash trigger is the perfect choice for the demanding underwater photographer who needs a reliable TTL converter that works with the most popular underwater strobes, including Inon, Ikelite, Sea&Sea, and Subtronic. As the LED of the trigger controls the strobe instead of the built-in flash of your camera, the camera's battery lasts much longer, so you need to open the underwater housing less often. The o-TURTLE 2 RC SMART+ features a new, more durable metal hot shoe, allowing you to check the battery status directly from the setup software.

RC mode is available in OLYMPUS & OM Systems.

This special setup is designed for photographers whose underwater housing lacks a proper LED output. It can be installed in M14, M16, or even Ikelite inch-threaded housings.
