The Plus IV's long triggering range is consistent with other PocketWizards but setting it to Long Range mode nearly doubles the triggering distance for difficult situations. For the maximum in extended range shooting place a Plus IV in Repeater Mode (RP) between your transmitter and receiver to repeat the signal and complete the connection.
The Plus IV is compatible with all Standard channel or simple triggering PocketWizard radios of the same frequency including PocketWizard-enabled photo gear from Profoto, Dynalite, Norman, Photogenic, and Sekonic light meters.
On-Camera TTL Flash / Remote Manual Flash
The Plus IV features a top shoe providing TTL compatibility with most Canon, Nikon, Panasonic cameras and flashes as well as some Fuji and Olympus gear. This allows photographers the versatility to shoot with an on-camera flash in TTL mode while triggering their remotes in manual mode. Easily slide a speedlight into the top shoe of your receiving radio and you are ready to start triggering your remote flash in minutes. A perfect setup for wedding photographers.
The top shoe on the Plus IV allows photographers to easily set-up their speedlights. No sync cord required.
Simple User Interface
The Plus IV has an intuitive user interface where all channels, zones and modes can be easily engaged via a soft-touch keypad, and displayed on an easy-to-read backlit 1" LCD display. When you're working in dark environments, simply press any key other than TEST to illuminate the LCD.
With 32 channels (16 standard plus 16 Quad-Zone Triggering channels), the PocketWizard Plus IV Transceiver enables you to trigger individual or groups of lights simultaneously or individually. This is critical for working in crowded venues or with multiple lighting set-ups.
Selective Quad-Zone Triggering keeps you shooting photos, not running back and forth to your lighting or cameras. Without leaving the camera position, you can wirelessly activate or deactivate your remote flashes or cameras in 4 separately controllable zones: A, B, C, or D. This is ideal when using multiple lighting setups or turning remote cameras or flashes on and off as needed.
With its patented Auto-Sensing Transceiver technology, the Plus IV Transceiver is one smart radio. When set to TxRx, it will instantly and intelligently switch between transmitter and receiver modes as needed for greater flexibility on the job. The Plus IV may be set to transmit (Tx) or receive (Rx) independently if needed.
Two-Stage Remote Camera Triggering
The Plus IV Transceiver is the perfect solution for remote camera triggering. The unique two-stage TEST button on the Plus IV works just like the shutter release button on your camera. Press it halfway and your remote camera wakes up to meter and focus. Press TEST all the way to take your photo. When released, your remote camera will return to sleep mode normally: a real battery saver.
Our Auto-Sensing Transceiver technology lets you trigger a remote camera in sync with remote flashes using only 3 PocketWizard radios: the one in your hands, a Plus IV cabled to your remote camera, and the one connected to your remote flash set to one channel higher.
Range is comparable to other PocketWizard radios. Shooting environments are seldom ideal, so the Plus IV incorporates two range extending modes for the challenges of the real world. Use Long Range Mode (LR) to nearly double the effective triggering distance in almost any environment.
Repeater Mode (RP)
In very challenging environments or extremely long working ranges, place a Plus IV in Repeater Mode (RP) between your transmitter and receiver to repeat the signal and complete the connection. These modes take a little extra time to do their jobs, so maximum X-sync may be reduced when firing remote flashes in LR or RP modes.
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 today's cameras. This mode can also help high fps triggering compatibility for any flash.
External Power and Firmware Upgradeable
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.
