The PocketWizard TTL Wireless Radio Kit is a perfect option for photographers with Nikon Speedlights. It includes 3 FlexTT5 transceivers, an AC3 ZoneController, and a G Wiz Uber bag to keep everything together. Use one FlexTT5 on your camera with the AC3 and a FlexTT5 with each of your Nikon Speedlights. You instantly have the ability to control two remote flashes in either manual or TTL mode, independently. Just turn the dial on the AC3 to increase or decrease power levels, right from your camera’s position. With FlexTT5s, you can also shoot seamlessly up to 1/8000 in manual or TTL mode. If you have White Lightning or AlienBees strobes, add in the AC9 AlienBees Adapter and control the power of your strobes directly from the AC3. No more walking over, climbing up a ladder, or hiring an assistant to slide the lever by hand! Photographers will love the ease of getting everything they need to start triggering a remote flash using TTL or manual modes in one package. It is the perfect solution for on-location or in the studio.
