Announcing Flash Trigger for Canon

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. Warning: Don't try this at home! Rapidly firing a strobe in air could cause damage.

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.


Supported Housings:

Canon EOS 5D Mark III
Canon EOS 1D X and Canon EOS 1D C
Canon EOS 6D

* 2013 model YS-250 strobes have been tested and function properly. Earlier models may have less sensitive slave sensors and be incompatible. ** Sea & Sea YS-D1, YS-01 and YS-250 strobes require the installation of an optional flash prism for reliable triggering. Prism model numbers are 26312 for NA-1DX/NA-5DMKIII, and 26313 for NA-6D.

Model Number: 26301
