Some users have reported 580 EX II flashes failing while using Pocket Wizards. There is no proof that they caused the issue, but, the range issue and the unknown reason for flash failures are troubling.


The sock is just plain Rube Goldberg. PW put the Mini / Flex on the market knowing that it only had about 15-50 ft range with the 580 EX II, but claimed 400 or more ft. It took them several months to devise a shield.


Another issue is new camera models. There is not only no guarantee that the PW will work with a new camera model, but it seems likely that as new camera features are added, you will have to wait for a fix, assuming it can even be done.
