• Flashes with reversed polarity (the center contact on the hot shoe is minus) cannot be used due to the risk of damaging the camera and/or flash.

•Do not combine with accessories that have a different number of contacts, such as a Hot Shoe Grip, as a malfunction may occur.

•Combining with flashes from other manufacturers may cause equipment breakdown. We recommend using the AF540FGZ, AF360FGZ or AF200FG.
