PocketWizard AC5 RF Soft Shield for Flex TT5

AC5 RF Soft ShieldThe 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). Other Canon flashes, including the 600EX-RT, emit relatively low EMI and work well with the FlexTT5 without shielding. 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. NOTE: The AC5 is not designed for horizontal use on a boom mount or light pole; for these situations please see the AC7 RF Hard Shield above. The AC7 is also the perfect solution for use with an umbrella with its centered umbrella mount.
