If the aspect ratio is changed (p. 55), more images can be shot because the data size per image will be smaller than with 4:3 images. However, since 16:9 images have a setting of 1920 x 1080 pixels, their data size will be larger than 4:3 images. Approximate Values for Paper Size (for 4:3 Aspect Ratios) A2 (16.5 x 23.4 in.)
