QMS-D1 Wireless Digital Camera Flash Booster / Slave

Quantaray QMS-D1 Digital Slave Flash Booster with auto slave and delay time function The Quantaray QMS-D1 is a pocket sized flash optimized for use with digital cameras. This wireless booster flash does not need to connect to your camera or main flash in any way. It comes equipped with an electronic slave trigger that discharges the flash when it sees the main flash go off. That makes it a very handy piece for filling in shadows, increasing the output of your main flash or for special effects. It comes equipped with a tilting, table-top stand or it can be put into a regular flash shoe or it can be attached to any tripod. A digital camera or a digital flash unit fires pre-flashes to obtain necessary information on the subject to be photographed and evaluate the required lighting output or to reduce red-eye effect. The QMS-D1 slave flash can automatically detect the different pulses (i.e. pre-flashes) and fires in synchronization with your camera's main flash. As different digital cameras' built-in flash or external flash unit has different pre-flash delay time before actual activation of the main flash, the QMS-D1 has three slave settings that should be selected and tested before actually taking your photos to ensure that the correct slave flash synchronization is selected. S: The QMS-D1 will be activated instantly when it detects a flash light which could be a pre-flash from the camera's built-in flash or external flash. ( The activation at this setting is exactly the same as that of the QMS-1 slave flash unit (53-166-0769)) . This slave setting is to be selected for traditional cameras or flash units that do not fire any pre-flash. S1: At this setting, the QMS-D1 can detect the pre-flash light of the digital camera's built-in flash or external flash unit with single pre-flash function and delays the activation and synchronizes with the actual main flash light emitted after the pre-flash. (e.g. Synchronizes with the built-in flash or main flash of most Canon, Olympus, Nikon and Sony digital cameras) S2: At this setting, the QMS-D1 can detect the pre-flashes light of the digital camera's built-in flash or external flash unit with double pre-flashes function and delays the activation and synchronizes with the actual main flash light emitted after the pre-flashes. (e.g. Synchronizes with the built-in flash or main flash of most Nikon digital cameras)
