ok when i got my xti i got a sandisk ultra II 1.0gb compact flash card... is that holding me back as far as speed in my shooting? if so what should i get for faster shooting? also, i dont know what it is called but im wanting something that i can attach to my camera so that i dont have to hold down the button on top of the camera to take a shot. i want to be able to do it from afar with a press of a button that wont shake the camera. plus i want to be able to do some self portraits and practice to get my black background set up please help with links / feedback. greatly appreciated.
