Abstract
The invention discloses a manual iris for a camera. The manual iris for the camera comprises a baseplate support, a plurality of blades rotatablely connected on the baseplate support through a blade spindle, a plectrum capable of rotating around a plectrum spindle and connected on the baseplate support, and the plectrum spindle is parallel to the blade spindle. The manual iris for the camera further comprises a manual control device of irises. The manual control device of the irises comprises an operating part capable of rotating around an operating spindle and connected on the baseplate support. A driving lever post is fixedly arranged on the operating part, a driving elongated slot is formed in the plectrum, lengthwise direction of the driving elongated slot is the same with radial direction of a circle which adopts axis of the plectrum spindle as center of the circle, and the driving lever post is inserted in the driving elongated slot. By means of rotating the operating part, the plectrum is driven to rotate around the plectrum under match of the driving lever post and the driving elongated slot, and therefore opening and closing of the plurality of blades are controlled, and the irises are adjusted manually. The manual iris for a camera is simple in structure and low in production cost.
