Multi-point Focus Shooting
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 op-
eration. 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.
When the instant auto-iris switch is pressed during manual iris
operation, the iris changes to automatic operation mode while
the switch is held down.
NOTE
The automatic iris operation may not be performed
depending on the types of cameras.
(Only models with built-in extender)
The lens with built-in extender has the built-in 1.5x extender.
Use the extender lever to switch between 1x and 1.5x.
NOTE
When the extender is used, note that the light quantity may
decrease by the zoom ratio depending on the iris correction
setting.
To operate the macro, press the macro button to unlock the
macro ring. While holding it down, turn the macro ring at the rear
of the lens clockwise as viewed from the camera side to allow
macro shooting.
1
Set the lens to the widest angle by manual or servo zoom
operation.
2
Bring the object into focus by turning the macro ring.
NOTE
Macro operation is also possible at any zoom position other
than the widest angle, but the object distance increases.
