The TTL Wireless Radio 5-Pack for Canon was put together by PocketWizard to give photographers the benefits of wireless triggering, backed with the automation of TTL exposure. The kit includes two FlexTT5 Transceivers, an AC3 Zone Controller, and a padded G-Wiz Uber Bag.
The low-profile MiniTT1 Transmitter is ideal for triggering speedlights or strobes attached to the FlexTT5 Transceivers in this kit. The TT1 has 56 channels over 26 frequencies, a TTL range of 800', and a basic triggering range of 1200', and since we're dealing with a radio signal, it goes through obstructions rather than being blocked by them. The hot shoe on top of the unit allows you to use a TTL flash on camera while sending TTL signals to remote flashes and triggering manual flashes simultaneously, a great benefit for wedding photographers. Whatever your setup, you'll also be able to set exposure compensation on your TTL flashes and power levels on the manual units.
The PocketWizard FlexTT5 Transceiver Radio Slave is part of a versatile radio slave system and is dedicated specifically to the Canon E-TTL flash control system. It simply slides directly into the camera's hot shoe, and there are no special settings to make or modes to call up. Use the camera, on-camera flash, or flash commander controls for flash compensation, zone, and ratio control. It supports single or multiple dedicated flash units.
The FlexTT5 is the ideal addition to any Canon E-TTL flash system. Since this system works on digital radio technology, it can support TTL operation around corners, out-of-sight, or in bright sunlight. The FlexTT5 is a transceiver, meaning it can be used either as a transmitter placed in the camera's hot shoe or as a receiver accepting the transmitter's signal for flash triggering. This setup requires 2 FlexTT5s like the ones included in this kit.
The AC3 ZoneController gives you total control of your flashes from the camera position, whether you're working in TTL or Manual. You can place your lights in any of the AC3's 3 zones and adjust the power settings in 1/3rd stop increments over a 6 stop range. Choose which zone to fire and when or fire them sequentially to sync with flashes faster that you could with a single flash. For specialized work, you can even fire a series of cameras sequentially. When using Auto mode, TTL and Power Tracking are engaged, meaning that the AC3 will automatically recalibrate for changes in ISO or aperture.
G-Wiz Uber Bag
Designed to hold the MiniTT1 and the FlexTT5, the G-Wiz Bag is constructed of durable rip-stop nylon and padded to protect your radios. The interior has foam cutouts to provide the perfect fit for your gear. Additionally, the bag has two interior zippered pockets for accessories as well as an exterior cable pocket, so you can keep all your accessories right alongside your remote. Next time you travel, don't worry about your radios getting crushed; use the G-Wiz Uber bag, and be sure they arrive intact.
