Description: The YS-27DX strobe is designed for multipurpose underwater photography. This new strobe has beam angle of 105° x 84° and a guide number of up to 20 (ISO 100 / m) / 66 (ISO 100 /feet)- providing spread and power for subjects that range from wide-angle macro. The light level control dial of the YS-27DX has nine different light level controls- which increments from a minimum power of GN 1.7 to a maximum power of GN 20 (1EV step). The light level control dial makes you to take ideal pictures- precisely adjustable to get just the right amount of light for the subject at hand. The YS-27DX offers a pre-flash cancel mode (*1) that ensures the strobe won't fire prematurely when used with digital cameras that emit a small pre-flash burst before the main flash. This strobe is compatible with most digital cameras that have a pre-flash An optional fiber optic cable accurately synchronizes the strobe with your digital camera's built-in flash. The YS-27DX's power source is four AA batteries- which provide strength and endurance for a full day's shooting without changing batteries. The recycle time of YS-27DX with 2700mAh nickel-metal-hydride batteries is only two seconds- providing speedy recovery for a rapid series of images. SEA&SEA adopts the dela-prism- which spread soft and delicate lighting of subjects- for YS-27DX. The YS-27DX is an ideal slave sub-strobe for a digital SLR camera housing. It detects light fromthe main strobe's Flash and immediately fires in synchonize with the main strobe. *1 Some digital cameras adjust flash levels after a first flash and then capture an image with a second flash. This first flash is called the “pre-flash.” The strobe’s pre-flash cancel function ignores the pre-flash and synchronizes the strobe with the second flash. *The YS-27DX is not compatible with digital cameras that emit two or more pre-flashes.
