Adjusting the Flange Focal Length

Adjustment of the flange focal length (the distance between
the lens mount attachment plane and the imaging plane) is
necessary in the following situations:
• The first time a lens is attached
• When changing lenses
• If the focus is not sharp at both telephoto and wide angle
when zooming
The flange focal length can be more precisely adjusted by
using the focus assist indicators.
See "Displaying the focus assist indicators" on page 28 for the
focus assist indicators.

Attaching a Viewfinder

Caution
When the viewfinder is attached, do not leave the camera with
the eyepiece facing the sun. Direct sunlight can enter through
the eyepiece, be focused in the viewfinder and cause fire.
