Nauticam Announces Flash Trigger for Canon

New Trigger allows Canon cameras without popup flash to use Fiber Optic cables

Nauticam has just announced a long-awaited flash trigger that allows use of fiber optic cables with Canon cameras that don't have pop-up flashes. These include the Canon 5D Mark III, EOS 6D, EOS 1D X and EOS 1D C. Underwater photographers using these cameras can now benefit from the simplicity of fiber optic cables (vs. sync cords).

In addition, since these cameras don't use a pop-up flash that needs to recycle after firing, the new flash trigger unit allows divers to shoot as fast as their strobes will recycle!


Why is this Important?

  • Fiber optic cables are easy to set up, maintain and are less prone to flooding than sync cords
  • Continuous (rapid) shooting is not limited by the on-board flash recycle time




Innovation Underwater continues as Nauticam is pleased to announce the first in it's line of flash trigger units, allowing use of robust and reliable fiber optic cables to fire external strobes. The Flash Trigger for Canon works with Canon cameras without popup flashes, like the EOS 5D Mark III, the EOS 6D, EOS 1D X and EOS 1D C, providing dependable, rapid-fire flash triggering over fiber.

Flash triggers allow motor drive shooting sequences, perfect for fast moving action.  Since the popup flash is not used, the camera does not have to wait for the popup flash to recycle, meaning faster shooting, less heat buildup, and longer camera battery life.  Shoot as fast as your external strobes can handle!

Video demonstration of the Flash Trigger for Canon. To capture the rapid flashes, this video was shot at 60fps; however, to share on the internet it had to be re-coded to 30fps. While not as smooth as it would be with 60fps, it does demonstrate how fast the Flash Trigger responds. 

This flash trigger is manual only; automatic flash exposure (TTL) is not currently enabled - a tool for reliable, fast external flash firing.  Supported strobes include the Inon Z-240 Type 4, D-2000 Type 4, S-2000, Sea & Sea YS-250*, YS-01**, and YS-D1**.

Shooting with Fiber Optic cables means shooting with confidence. There are no sync cables to flood or corrode, meaning much higher reliability, and the strobe can even be removed from the rig, while underwater, for off-board lighting opportunities. Nauticam fiber optic cables have the highest light throughput of any optical cables on the market, making the Nauticam Flash Trigger even that much more reliable.

The Flash Trigger for Canon weighs under 70 grams, including batteries, and mounts on the camera hotshoe, locking in place with a locking lever. It uses 2 CR3032 batteries, which combined with the highly efficient LED trigger lights, provide for thousands of flashes (5000 estimated). An LED status indicator informs the user that the unit is on and functional. It fits perfectly into the supported housings, listed below. New housings for Canon SLR cameras will support the Flash Trigger as well.
