Hello, Today I am going to be reviewing/looking at the Impact PowerSync 2.4GHz Wireless Receiver & Transmitter. These allow almost any DSLR/SLR with a hot-shoe adaptor to fire either, strobes, and or wireless flashes. These are very useful little things, and the cool thing is that they are very expandable. I really like them! Yes.. they are expensive but way worth it! I would definitely recommend them if your looking to do anything with off-camera flashes. Thanks, chargerfun34
