2.调节后焦

根据刻度偏移值,参考下表调整相应的垫片,即可完成后焦调整。

调节过程,请执行以下步骤。

步骤一

旋转对焦环直至画面达到清晰状态,以“定焦镜头后焦校准工具

 

”中间

的横线为基准,观察此刻刻度指针的位置,并观察刻度指针偏移的横
线条数;

步骤二

注    意

若偏向无穷远方向,则代表刻度偏移值为正数;
若偏向最近对焦距离方向,则代表刻度偏移值为负数;
若超过

格横线,则用对应数值加减即可。

举    例

若刻度指针指向的刻度线朝最近对焦距离方向偏移

3

格,则刻度偏移

值为

-3

若刻度指针指向的刻度线朝无限远距离方向偏移

4

格,则刻度偏移值

+4

,此时需把“

+3

”的垫片值加上“

+1

”的垫片值即可。

提    示

后焦垫片调整值,“+”代表要增加垫片厚度,“-”代表减少垫片厚度。
