Pocket Wizard AC5 RF Soft Shield With RF Shoe Filter, For Canon Digital

The AC5 RF Soft Shield is a simple solution to reduce interference and improve performance of the FlexTT5 Transceiver. Special RF fabric and a shoe filter shields the FlexTT5 Transceiver from RF noise emitted by some Canon Speedlites (580EX II, 580EX and 430EX).  The AC5 allows easy access to all flash controls as well as a full range of flash positions. The AC5 can either be stored on the flash or it can be removed and rolled up making it easily storable in your camera bag. It's portability makes it an attractive RF noise solution. The AC5 RF Soft Shield can be used when using a high-power external battery. The AC5 is for use with receiving flashes only and is not for use with your on-camera flash.
