Cannot preview shots in lcd with new Canon Rebel xs 1000d
There are two modes to the XS's Live View system, selectable via
Custom Function 7. Live View is disabled by default, by the way, so
you'll need to find this menu item in Settings Menu 2 to turn it on.
The two options are called Quick and Live modes. Quick mode works as
most Live View modes do, dropping the mirror when you press the AE-Lock
button (marked with an asterisk) to use the conventional phase-detect
autofocus system. This temporarily blacks out the Live View image,
which makes it impossible to know that you're still framing the subject
and holding your AF point in the proper place.
That's why they added the second mode, which they call Live, but is better
described as contrast-detect autofocus. This works just like a digicam, reading
the image from the imaging sensor while adjusting the lens for the setting that
produces the most contrast in the image. A small square appears in the center
of the image area, and you can move it around with the cross keys. Just like
Quick mode, unfortunately, you have to press the AE-Lock button first until
you hear the focus confirmation beep, then press the shutter button to fire.
It's a little slower at times than phase-detect mode, but it gets the job done.
Live mode is really better for tripod work, where you can place the AF area
right where you want it and confirm focus onscreen.
Both modes offer the ability to zoom in on your live view, excellent for confirming
focus before capture. Using the Magnify button just right of the AE-Lock button,
you can zoom in 5x or 10x, then press the AE-Lock button to focus if you like;
but of course you can't confirm framing in that mode.
