Triggertrap Flash Adapter This is the next level of Triggertrap Mobile photography: triggering your flash directly from your smartphone! The Triggertrap Flash Adapter is perfect for the sort of really high-speed photography that a conventional camera cable release isn't quick enough to catch. Only compatible with ISO standard hotshoe flashes (not compatible with the Sony/ Minolta style hotshoe) Must be used with the Triggertrap Mobile Dongle. Never attempt to connect a flash directly to your smartphone. This flash accessory must only be used with modern, portable electronic flashes. Use with studio equipment or with high-voltage flashguns may damage your smartphone. A note to Android users: The Triggertrap Mobile app for Android is not yet optimised for high speed photography with the Triggertrap Flash Adapter. Although you will be able to trigger your flash, delays inherent in the Android operating system means that our Android app can’t be considered a truly high-speed device, therefore we recommend this product for use with the i OS version of the app only.
