The FX-380 Wireless Shutter Release Kit operates at 2.4GHz frequency which gives the user a longer working distance (up to 220 feet) and less potential conflict with other frequencies. The FX-380 features an Auto Coupling Capability (ACC) channel setting ability which makes syncing the transmitter and receiver easier than ever by just a push of the button. A time-lapse function has been built into the wireless remote to give the user more photographic options in one handy device. The built-in magnetic poles on the transmitter and receiver help the user keep them together when not in use. The interchangeable camera cable works with a variety of DSLRs including the Sony A350, A300, A200, A700, A900, A100, A380, A500, A550, A850, A450,A290, A390, A580, SLT-A33, A55.
