Overview The FlexTT5 Transceiver for Panasonic is a remote triggering and control device designed specifically for Panasonic's Lumix flashes. With 52 channels over 26 frequencies, the FlexTT5 offers wireless TTL auto exposure of 1 or multiple flashes at impressive distances comparable to other PocketWizard radio products. PowerTracking automatically adjusts for changes in shutter speed, f-stop or ISO. Distribution into 3 groups of flashes is possible with an unlimited number of flashes per group. High Speed Sync is also supported for shutter speeds shorter than the manufacturer's standard sync speeds. Another type of HSS - HyperSync uses precise timing to give you more light from your flash and is ideal for using power packs or high-powered strobes to freeze action or manage ambient light levels at shutter speeds as short as 1/1250 sec. Auto-Relay Mode can also trigger both a camera and a flash remotely with or without TTL control or both at the same time.The FlexTT5 is PocketWizard compatible meaning that it will work with all PocketWizard radio units and OEM partner products like those in Profoto, Bowens, Dynalite and Lumedyne flashes in non-TTL mode provided they're on the same frequency. The FlexTT5 has USB connectivity that allows you to use a free utility to tweak features like the HyperSync settings and take advantage of updates to future proof the transceiver.
