How to Focus in Live View Mode on a Canon Rebel T5/1200D
You can magnify the Live View display Canon Rebel T5/1200D to ensure that focus is accurate. This trick works during manual focusing or in any AF mode except Face+Tracking mode. After setting focus, follow these steps to magnify the display:
Use the cross keys to move the focusing frame over your subject if needed.
Press the AF Point Selection button to magnify the display.
After you press the button, you see a magnification frame somewhere on the screen plus a white box in the lower-right corner, as shown on the right in the figure below. The white rectangle is a thumbnail representing the entire image area.
The value x5 appears above the thumbnail to show you that you’re viewing the image at five times its regular size. Press the AF Point Selection button again to zoom the view to 10 times magnification. You can scroll the display as needed by pressing the cross keys.
To exit magnified view, press the AF Point Selection button again.
Just a couple of tips on using this feature:
Press the Set button to quickly shift the magnification frame back to the center of the screen.
Exit magnified view before you actually take the picture. Otherwise exposure may be off. However, if you do take the picture in magnified view, the entire frame is captured — not just the area currently displayed on the monitor.
