TTL Strobe Exposure

This bulkhead is capable of providing TTL communication when used in a compatible system. TTL or “Thru-the-Lens” flash metering means the camera evaluates the scene and communicates exposure information directly to the external flash. The camera adjusts the power output of the external flash each time the shutter is depressed.

TTL exposure is faster and often more accurate than setting the flash output manually. TTL can be the difference between getting a properly exposed image or not, especially when shooting fast-moving subjects and subjects that are moving towards or away from you. TTL is by far the easiest way to shoot perfectly exposed macro photography and allows you to concentrate on focus and framing. When shooting wide angle or close focus wide angle (CFWA), set your camera to properly expose the background and let the camera adjust your strobe intensity for proper exposure of the foreground.

TTL exposure requires a compatible camera, TTL hotshoe, DS Link TTL Converter, current model Ikelite DS series strobes, and an Ikelite-to-Ikelite single or dual sync cord. Refer to the table below for TTL hotshoe and converter availability by camera manufacturer.

ICS-5 Plug and Bulkhead

The Ikelite ICS-5 bulkhead was designed as a more robust and reliable alternative to the finicky Nikonos V film camera bulkhead. Compared to Nikonos V (also known as N5) fittings, the ICS-5 connector system features larger and more robust gold-plated contacts. Most importantly, the easy-to-see half-moon indexing design makes it easy to orient and attach the plug connection quickly and correctly.

ICS-5 fittings have been used for decades in the most demanding industrial and commercial applications. They are often imitated and widely appreciated as one of the most reliable waterproof connections for electrical signal transmission.

TTL can even work on highly reflective subjects underwater, which can be one of the most challenging lighting scenarios.

Housing Compatibility

Compatible with select housings by Nauticam and other manufacturers featuring a spare M16 threaded accessory port. Hotshoe compatibility is based on camera manufacturer, desired cable direction when looking from the back of the camera, and whether a compatible TTL converter is being used.

It is recommended to water pressure test and/or take an empty housing diving at your maximum depth after installing this bulkhead and before installing a camera in the the housing. Tightness of the bulkhead to the housing body should be checked on a regular basis.

Sync Cord Compatibility

This bulkhead is only recommended for use with newer sync cords featuring black hard anodized plug fittings with product numbers starting with the numbers “45.” Older nickel plated brass sync cord fittings may damage the threads and seize up.
