To shift the lens, turn the shift lock knob counterclockwise to loosen. (Fig. 1)
Shifting the lens for shooting
Turn the shift knob to adjust the amount of shift. The amount of shift can be adjusted in a range of ±12mm with the thick line on the shift scale as a reference. (Fig. 2) (A shift scale is also located near the shift lock knob.)
Focus the shot by turning the focusing ring. (Fig. 3)
Turn the shift lock knob clockwise and lock it before taking the shot. (Fig. 1)
Do not turn the shift knob forcefully. This may cause malfunction.
Locking the Lens in a Non-Shifted Position
Turn the shift knob so that the thick line on the shift scale is aligned with the shift index (at a click position). (Fig. 1)
Turn the shift lock knob clockwise to lock. (Fig. 2)
For EOS cameras with built-in flash, the lens may contact the camera while you operate the shift function.
With large amounts of shift, the amounts of peripheral light at the top and bottom or left and right sides of the screen may differ, so shooting with a small aperture is recommended.
The shift operation will be easier if the supplied cap is mounted on the shift knob.
