PocketWizard AC7 overview

  • 1Description

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.

PocketWizard AC7 reviews

AC7 RF Shield for FlexTT5 is rated 4.1 out of 5 by 27.
Rated 4 out of 5 by from Great product - a few short comings If you are looking at this product, it means you have issues with your pocket wizards firing your 580 EX series flashes. This shield will help improve the distance that you can fire your pocketwizards from. I have had very few misfires in the few weeks that I have been using this shield so overall, I am very happy. the only complaint I have is that the flash head is difficult to angle up when the shield is on (it's much easier to take the flash off, angle the flash and then put it on again. Unfortunately, as a wedding photographer, this takes a lot of time which makes it a pain in the neck. Other than that, this shield works great!

Rated 5 out of 5 by from A must for PW TT / 580EXII I was about to give up using our 580's with Pocket Wizards when we discovered this shield. Made all the difference in the world. Increased our range and firing accuracy 2 or 3 times from what it was. No more missed flashes, our 580EX II's now work as well as the Profotos or Einsteins we use in the studio. If you own 580s and use TT's I'd consider this a MUST HAVE. The TT's are useless without it. Shame on PW for not getting the range right the first time, but I will say the AC7 adds a nice functionality to the mix with its holder that doubles as a pistol grip / umbrella holder. Don't leave home without it!

Rated 3 out of 5 by from Shoes become loose and come off easily There are a few problems with AC7, but the one others don't talk about is that the screws that hold the flash shoes become loose very easily, and when you try to re-tighten the screw, you'll realize that the thread in the plastic part is worn out so the screws are never tight again. I learned this problem the hard way, and also lost some screws. Unless PocketWizard is willing to send me the repair parts, this piece of plastic is not worth sending back for repair (performed by Mamiya America Corporation - one of the most expensive camera service company in the world!) and so I'll be glueing the thing and be done with it.

Rated 2 out of 5 by from Shame on PocketWizard This RF Shield does what it is supposed to. Makes a product that is dedicated to Canon flashes, work with Canon flashes. This should absolutely NOT be an additional purchase. The 580EXII was on the market long before PW created this product. The issues with the 580EX II giving off strong and variable amounts of RF has been part of the 580 since it hit the market.... PW knew this problem existed, yet they still released a product that wouldn't work properly unless we forked out another $30+/- to make it work. This is really silly. If I buy a car, I shouldn't have to now buy an engine to make it work. Anyway, other issues include problems connecting some power cables, issues connecting any light modifiers to the 580 when it is installed (not enough clearance to connect anything to the snoot of the flash), extra bulky item to add to your gadget bag, cheap cold shoe foot which will absolutely break, and you need to buy mounting hardware since you are not allowed to use the hot shoe attachment. (The hot shoe attachment is available for use, but the instructions clearly state that using the hot shoe will re-introduce RF problems. When you use this RF shied, you are to explicitly use the mounting holes on the side of the unit.... which meant that I needed to fork out another $50 for a mini ballhead and a cold shoe adapter, for EACH of my three RF Shield).

Rated 3 out of 5 by from Its work! Improves performance! Reason why 3 Stars, Use Canon 580EX with CANON Compact Battery Pack CP-E4. you can NOT use with CANON factory Compact Battery Pack CP-E4 cable Cord, impossible to fit on Anti-modifiable AC7 RF HARDshield. Cord is little thicker than gap between 580EX and AC7. If your using Quantum Battery Pack with CZ2 Dedicated Flash Cable is possible to fit with a little physical strength & psychology stress. Conclusion, Only Two way, go get Quantum Battery Pack or Powerful AA batteries, Like Ansmann AA 2850mAh Capacity Rechargeable NiMH Batteries. This Batteries is so powerful! it made my 580EX burnout with external Battery Pack :) Anyway, Its work! Improves performance with Canon 580EX!

Rated 4 out of 5 by from AC7 RF Shield is worth it If using Canon 580EX II, this is an absolute must to help extend the range of your PW's. Biggest advantage - range! Increased the range on my 4 lights from 10ft to over 50ft - no probs! The umbrella holder is also nice, but I don't use umbrellas that much (see below). Disadvantages - it is a bit of a mission getting the flash in and out, connecting external power needs some balancing acts and attaching my softboxes to 580's required some engineering... (this is what my assistants tell me :) ) It is a nuisance to buy yet another accessory with the PW's, but that's life... Overall - for what I use them I am satisfied. Well worth the extra dosh if you need the extra range.

Rated 3 out of 5 by from a should-not-be necessary evil I use it for the reason it came to be: to reduce or eliminate RF interference from Canon's 580 EXII with Pocket Wizards. PW should have designed around the problem, not issued some clumsy and pricy after-thought fix. It's expensive, too big and not well thought out. There is a an alternative, however; one that leaves Pocket Wizard in the dust: Canon's new 600RT strobes. No need for PWs at all! Consider this: a 600 RT costs less than a 580 EXII + AC7 + the PW TT5, does more and does it better.

Rated 3 out of 5 by from Missing a slot Makes a big difference in the distance. With the shield I am able to trigger it at over 300 ft - only 20 without. Only one issue, need a slot on both side. If you want to tilt the flash to 90 degree, the head must be rotated 180 degree and the push button ends-up on the opposite side of the slot (as manufactured). I have modified mine immediately now it works just fine. Like others mentioned it is a bit tricky to put the flash on the hot shoe. On a negative note - realized that Pocket Wizard has no customer service at all. They want you to contact the vendor, not them.
