How to Use the Monitor as Viewfinder on the Canon Rebel T/5 1200D
For your convenience, the T5/1200D offers Live View, a feature that enables you to use the monitor instead of the viewfinder to compose photos. You also must rely on the monitor for recording movies; the viewfinder is disabled for movie recording. How you activate Live View depends on whether you want to shoot still photos or movies:
Live View for still photography: First ensure that Live View shooting is enabled in the menus. Where you find the option depends on the setting of the Mode dial: In the P, Tv, Av, and M modes, the Live View option is found on Shooting Menu 4, as shown on the left; in all other modes but Movie mode, the option appears on Shooting Menu 2, as shown on the right.
Why disable Live View? Because it’s easy to hit the Live View button accidentally and switch to Live View when you don’t really want to go there.
After enabling the feature on the menu, press the Live View button. You hear a clicking sound as the internal mirror that normally sends the image from the lens to the viewfinder flips up. Then the scene in front of the lens appears on the monitor, and you can no longer see anything in the viewfinder. Data representing certain camera settings is displayed over the live image.
To exit Live View mode and return to using the viewfinder, press the Live View button again.
When looking at Live View screens, you’ll notice that data along the sides and bottom of the screen appears differently as superimposed over the image.
Live View for recording movies: Rotate the Mode dial to the Movie mode icon. Live View engages automatically, and you then press the Live View button to start and stop recording. To exit Movie mode, rotate the Mode dial to any other exposure mode.
In many ways, shooting photos in Live View mode is the same as for viewfinder photography, but some important aspects, such as autofocusing, work very differently.
