Powerful manual controls from wide-angle to macro photography
The YS-27DX strobe is designed for multipurpose underwater photography. This 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 control, 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 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.
*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.
