5-5. MACRO OPERATION
In macro shooting, the object distance becomes shorter than the normal minimum object distance (M.O.D.).
The minimum object distance by macro operation for this lens is 10mm at the widest angle.
In macro shooting, when zooming to change the focal length, the focal point varies.
The multi-point focus shooting technique uses this characteristic. The focal point is shifted by the zoom
operation. Follow the steps bellow :
1
Zoom in to a far object, and bring it into focus by normal focus operation.
2
Zoom out to a near object and bring into focus by macro operation.
3
Zoom in to the far object again while not touching the macro button set by above step 2, and bring into
focus again by normal focus operation.
