The new PocketWizard Plus IV Transceiver (Black) includes all the features and reliability of the Plus III and adds key new functionality. When used as a transmitter, its top shoe provides on-camera TTL compatibility with most Canon, Nikon and Panasonic cameras and flashes. And although testing is not complete, we are optimistic it will work with some Fuji, and Olympus gear. When used as a receiver, you can easily mount and trigger virtually any speedlight in the shoe, set to a manual power level. The Plus IV features the same Quad-Zone Triggering as the Plus III so you can easily turn any one of those remote flashes on or off directly from the camera, and either create different looks or work in different areas. Normally, the Plus IV is capable of triggering lights or cameras at a sustained rate of up to 12 frames per second (fps) - a standard for PocketWizard radios. Set the Plus IV to High Speed Receive Mode (HSR) and trigger at rates up to 14.5 fps, beyond the capability of most of todays cameras. This mode can also help high fps triggering compatibility for any flash. The Plus IV is normally powered by two AA (IEC:LR6) batteries. For long term remote placement, use an AC adapter, like the PW-AC-USB Adapter, that plugs into the standard Mini-B USB port of the Plus IV. The USB port also enables future upgrades of the Plus IV operating system.
The Plus IV has the performance enhancing features of the Plus III including Long Range and Repeater Modes to help photographers tackle the most challenging shooting environments, opening the door for never-attempted image ideas. All features, channels and zones can be easily set using the soft-touch keypad and are clearly displayed on the backlit LCD display. The versatile new PocketWizard Plus IV is compatible with all other PocketWizard radios and virtually every popular flash and professional digital SLR camera system. The standard ISO compatible hot shoe can accommodate almost any spee
