Product Information
Full details
The PocketWizard AC5 RF Soft Shield is an essential accessory for professional photographers using Canon Speedlite flashes with FlexTT5 or FlexTT6 transceivers who experience signal interference. This shield uses specialized RF-blocking fabric and an integrated shoe filter to isolate the transceiver from noise emitted by Canon Speedlite 580EX II, 580EX, and 430EX units, ensuring reliable wireless triggering. While it significantly boosts performance in high-interference environments, it is specifically designed for receiving flashes and cannot be used for horizontal mounting on boom arms or poles.

FAQs
Can I use the AC5 on my on-camera flash?
No, the AC5 is designed exclusively for off-camera receiving flashes.
Does it work with all Canon Speedlites?
It is optimized for the 580EX II, 580EX, and 430EX. Other models like the 600EX-RT have lower EMI and may not need the shield.
Can I use this with a boom mount?
No, the AC5 is not designed for horizontal orientation on a boom mount or light pole.
Does it block the flash zoom or controls?
No, the design ensures all controls remain accessible and the flash head can still zoom and tilt.
Is it compatible with external battery packs?
Yes, it is designed to work seamlessly even when a high-power external battery is connected to the flash.
Troubleshooting
Inconsistent triggering even with the shield installed
Check that the shoe filter is seated perfectly flat and that the fabric is fully covering the transceiver sides.
Difficulty rotating the flash head
Ensure the fabric is not caught in the flash head hinge; adjust the wrap slightly to provide more slack at the pivot point.
