Split-screen display zoom, which shows two parallel areas of the frame side-by-side at a high zoom ratio, can be used to frame buildings or similar objects from the front so that left and right sides are symmetrical.
Split-screen display zoom is available during live view photography.
Press the button and select Split-screen display zoom. Two areas of the frame will be displayed side-by-side at a high zoom ratio, with the positions of the magnified areas shown in a navigation window.
Use the and buttons to zoom in and out, or use the ( ) button to select a box and press or to scroll the selected area left or right. Pressing or scrolls both areas up or down simultaneously. To focus on the subject at the center of the selected area, press the shutter-release button halfway. To exit the split-screen display, press the button.
You may think you're framing an object symmetrically, but if you zoom in you may notice that the sides are at different angles to the camera and the perspective is asymmetrical.
To frame an object dead on so that the two sides are symmetrical and the camera angle on the left side mirrors that on the right, use the split-screen display to zoom in and compare areas from the left and right side of the frame.
Precise horizontal symmetry in architectural shots requires close attention to camera angle. Use the virtual horizon to adjust roll and pitch and split-screen display zoom to rotate (yaw) the camera horizontally.
1 Level the camera.
Start live view photography and press the button to display the virtual horizon, then level the camera using the pitch and roll indicators as a guide. The camera is level when both the roll reference line and the dot in the center of the display turn green.
2 Adjust the camera angle.
Using the split-screen display as a guide...
...rotate the camera horizontally until the angle on the left side mirrors that on the right.
PC-E perspective control lenses can be shifted or tilted without angling the camera.
Shift: Perspective Control
Shift slides the lens parallel to your subject without changing camera pitch, reducing the effects of perspective when tall buildings are photographed from street level. If the camera is in "portrait" (tall) orientation, split-screen display zoom can be used to align the top and bottom for more accurate perspective control.
Tilt: Focus Control
Tilt allows you to swivel the lens without rotating the camera, giving you control over which part of the subject is in focus. When adjusting tilt, use split-screen display zoom for a better view of the area that is in focus.
