I agree on the RT part. I really wish Canon would stop being so stingy with RT Master use. It's barely used at all except in expensive external devices. Come on, Canon! Integrate it into the camera! (Or at least make a low profile device useful.) The EL-100 was a perfect chance to do this. I would have paid another $100 to have RT master functions in the EL-100.I’d be excited if it was an RT master...but this? Meh.
But my dream is still for the RT Master to be in-camera and also have a small EL-100 "RT" so it would be easy to remove the flash and use it off camera with my hand/arm and keep shooting. (Or any number of other myriad flash scenarios where an in-camera RT Master would be ideal.)
