7. The shift/tilt function
Important
• Use of a tripod is recommended for correct shooting.
• Turning each knob too tightly can cause damage.
• Use of tilt/shift function can cause some vignetting. (Vignetting is
the darkening of the corners around the image.) To counteract
this, close the aperture (choose a larger f-number), or
compensate the exposure before shooting.
• Determining correct exposure with shift and/or tilt use requires
experience. We recommend that you take a series of test shots
until you feel comfortable with the operation.
The shift function
Fig. 7
When the shift knob is rotated, the lens is shifted horizontally (or vertically,
when the lens is revolved) parallel to the camera body (±11.5 mm).
By shifting, you can recompose the frame of the shot without
moving the camera. This lets you correct the perspective distortion
of the subject or exclude unwanted objects from appearing in front
of the main subject. (p. 217)
• After shifting, tighten the shift lock release knob to fix the lens’
shift position.
Note: When shifting the lens, be careful not to pinch your fingers
between the lens and the grip of the camera body.
