Create a long range wireless flash setup with ease by picking up the WT-1T Wireless Transceiver from Metz. By using a reliable 2.4 GHz radio signal and a selection of 15 channels, users will be able to trigger receivers up to 984' away, without requiring line-of-sight and with minimal interference. Also, this system is compatible with Canon's E-TTL / E-TTL II flashes, permitting both TTL and manual control options and support for high-speed sync at up to 1/8000 second. Users will even have access to a TTL pass-through hot shoe on the top for using a flash directly on camera or setting up this transceiver unit as a receiver.When multiple flashes are involved, the WT-1T offers group control with three groups for creating more elaborate setups. It also has a backlit LCD screen to show and change current settings as well as a standard sync port for use with studio strobes. Additionally, it has a USB connection for firmware updates.
