PocketWizard has taken the much loved Plus III transmitter and turned it literally on its side with the announcement of the Plus IV Transceiver. This model takes all of the incredible features of the Plus III and adds a hot shoe, enabling pass-through TTL compatibility with select flashes and the ability to easily integrate a manual speedlight into your wireless setup. It is compatible with existing PocketWizard triggers, enabling users to integrate one into their existing radio collection.
Sharing features with the Plus III, it has Long Range and Repeater Modes to ensure reliable triggering over long distances or through difficult terrain. It also has Quad-Zone Triggering for remotely turning flashing on or off from your camera. On the back is a soft-touch keypad and LCD, which are clearly marked for making fast adjustments, and the new flat design assists shooters by providing clearance for looking over the top of the camera. Additionally, the Plus IV has a durable metal foot.
As of the announcement, PocketWizard has tested TTL functionality with most Canon, Nikon, and Panasonic flashes, as well as select Fujifilm and Olympus equipment.
