In a digital SLR, a feature that allows you to use the LCD display as a viewfinder. Because the mirror in the camera must be flipped out of the way during live view, not all cameras are able to use their autofocus mechanism while live viewing. Different vendors offer different work arounds from temporarily flipping the mirror back down for a quick autofocus, to analyzing the image detail on the sensor and using a contrast-detection algorithm to calculate focus, to using a second focus meter near the image sensor.

Program Shift

Program Shift allows you select specific aperture and shutter speed combinations when you’re in a fully-automatic Program mode. Program shift features usually work like this: in Program mode, press the shutter button halfway to meter and lock focus. Now, adjust the Program shift control. The camera will automatically cycle through all reciprocal shutter speed/aperture combinations for that particular exposure. So, you end up with the same level of exposure, but you can choose between a shutter speed/aperture combo that has a faster or slower shutter speed, or larger or smaller aperture. Program shift gives you a great degree of manual control, even when you’re in a fully automatic program mode. Consult your camera manual for details.
