the two actuators are fixedly arranged in the lens barrel respectively.
该二个致动器分别固 定设置于所述镜筒内。
the lens barrel part is connected to a main body by a hinge unit so that it can be rotated with respect to the main body.
镜筒部分是连接到一个主体由一个铰链组,这样就可以与有关主体旋转。
then pull the focusing barrel out slightly, and the lens barrel can be swung over farther to the left, to get into the close focusing range.
然后轻轻将镜头的调焦筒拉出,镜筒就可以继续向左转动以获得更近的对焦距离。
this value controls the amount of distortion. negative values correct lens barrel distortion, while positive values correct lens pincushion distortion.
此值控制着畸变的量。负数值校正镜头圆桶状面性畸变,而整数值校正镜头针尖状点性畸变。
you can drop in 72mm filters at the rear of the lens barrel and there's even a mechanism to position a circular polarizing lens just the way you want it.
