The AC7 RF Shield for FlexTT5 solves the problem of limited performance of the FlexTT5 radio transceiver when operated using the Canon 580EX, 580EX II and 430EX flashes, caused by interference emanating from the flashes.
The AC7 is a hard plastic shield with a special RF coating that effectively blocks RF interference (EMI) from clouding the FlexTT5 antenna. To block noise traveling through connections in the hot shoe, an electronic filter has been added to a hot shoe built into the AC7. Combined, the AC7 shield allows the FlexTT5 to receive transmissions at distances 300 to 500% farther than before and well within the range of most off-camera lighting needs.
