Function settings particular to Live View shooting can be set under the [] menu tab. The functions settable on this menu screen only apply during Live View shooting. These functions do not take effect during viewfinder shooting.

The image's aspect ratio can be set to [3:2], [4:3], [16:9], or [1:1].

The following aspect ratios will be indicated with lines on the Live View image: [4:3] [16:9] [1:1].

JPEG images will be saved with the set aspect ratio.

RAW images will always be saved with the [3:2] aspect ratio. Since the aspect ratio information is appended to the RAW image, the image will generated in the respective aspect ratio when you process the RAW image with the provided software. In the case of the [4:3], [16:9], and [1:1] aspect ratios, the aspect-ratio lines will appear during image playback, but the lines are not actually drawn on the image.
