Product Details: The Canon PowerShot G5 X camera is the latest class-leading model from the venerated G-series of cameras. The G5 X is very similar in image quality and handling to its cousin, the G7 X, plus adds the critical ability to attach an external flash. This electrical flash connection provides extended battery life and rapid fire shooting beyond the capabilities of the G7 X and Sony RX100 series. Unlike the G16 and other preceding models, Canon finally gives us TTL flash in Manual mode-making this a new favorite for underwater photography. True Canon TTL: An integrated TTL circuit is fine-tuned to Canon's latest flash exposure protocol for the most accurate exposure possible with the Canon PowerShot G5X camera. The circuit is powered by the strobe for zero maintenance and no batteries to change. Exposure compensation in TTL mode is supported using the camera's built-in control. At this time, only Ikelite DS strobes are capable of powering the circuitry. SEA&SEA, INON, and Nikonos strobes will still enjoy fast recycle times and improved battery life, but must be used in manual exposure modes only. A fast and reliable strobe connection is essential to getting the shot underwater. This housing provides a direct electrical connection to the camera's external flash hot shoe. Cord attachment is as easy as screwing in a lightbulb, and the threaded fit prevents accidental detachment during use. The bulkhead connection has been moved to the top of the housing to keep cords out of your way and reduce strain on the cord ends. A variety of sync cord terminations are available for Ikelite, SEA&SEA, INON, or Nikonos strobes for ultimate versatility.
