Pocket Wizard AC7 RF Shield for FlexTT5

The PocketWizard 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.  

The AC7 also integrates a ¼-20 mounting device and umbrella mount to aid in positioning your flash where you want it. With two ¼-20 mounting points, the AC7 can be mounted both vertically and horizontally on light stands, clamps, brackets or simply handheld. The back of the flash remains open for complete access to the LCD and flash controls and there is access to the remote power port. The flash head can be rotated when using the AC7 shield due to a small cut-away in the side of the shield. When used with an umbrella, the AC7's lay-flat design places the flash more in the center of the umbrella than usual and produces a symmetrical light shape. Most of the popular diffusers, grids, snoots and reflectors can still be used with the shield in place.

An optional pistol grip makes hand-held flash a breeze. The grip's integrated umbrella holder places the flash in the best position; next to the umbrella post for incredibly even light dispersion and no unusual shadows.
