I have a canon t1i and I recently purchased the 580 exII with a wescott photobasics light stand and a 45" shoot through with black cover umbrella an adorama light stand bracket and a cheep square perfect wireless trigger that is supposed to go on my camera and the flash but nothing it comes with will connect to my flash. what do I need to get to make it work/connect and where do I get it or should I send the trigger back and get something else? any suggestions??? ???
