Argote Posted February 19, 2011 Share Posted February 19, 2011 With the pop-up flash firing mode the camera transmits automatic flash settings to the remote flash so you don't HAVE to put it in manual mode, also, the built-in flash doesn't really affect the photo. Depending on your Sigma flash it might work with wireless TTL. My current Sony body has Wireless High Speed Sync TTL and I've heard it works with Simga and Metz flashes. Canon had purposefully removed this feature from their lower end cameras until now... Link to comment Share on other sites More sharing options...
