PocketWizard Wraps Up Canon RF Noise Problem
If not, save the electrons ...
Surprised by not only the magnitude but the variable nature of radio frequency interference put out by some of the Canon flashes, PocketWizard has addressed the Canon flash RF issues with the release of the AC5 RF Soft Shield.
It's basically an RF-blocking cloth shield which muffles the Canon flash noise and allows the TTL/HS sync-capable remote units to do their thing. It was a Canon-specific design problem, and there were reports of signifcant levels of interference from some Canon flash owners.
Today's news is that PW is going a step further and making the AC5 shields available for free.
It was a rough hand to get dealt, from an engineering/design standpoint. But kudos to PocketWizard for doing the right thing and making them available gratis. The offer goes live today, and runs through Jan 31, 2010.
Future units are reportedly going to include the AC5's in the box according to Mark Wallace at Snap Factory, for whom we also have to thank for the range demonstration video shown above.
