Grid display
With [3x3 l] or [6x4 m], you can display grid lines to help you
level the camera vertically or horizontally. Also, with [3x3+diag n],
the grid is displayed together with diagonal lines to help you
compose with better balance by aligning the intersections over the
subject.
Exposure simulationN
Exposure simulation simulates and displays how the brightness of
the actual image (exposure) will look.
• Enable (g)
The displayed image brightness will be close to the actual
brightness (exposure) of the resulting image. If you set exposure
compensation, the image brightness will change accordingly.

displayed close to the actual brightness (exposure) of the resulting
image only while you hold down the depth-of-field preview button.
