Certain Canon DSLRs cannot auto-focus when you half press the Receiver/Viewer’s shutter
button in LV mode. They include the Canon Rebel XS (1000D), Rebel T1i (500D), and Rebel
XSi (450D). These cameras can auto focus by pressing the camera’s own * button.
The Canon 5D Mark II, 50D, 40D, 1D Mark IV, and 1Ds Mark III cameras
can auto focus by pressing the AF-ON button.
