Description
Technical field
The present invention relates to single anti-camera lens field, more particularly to a kind of switching drive system and method for camera lens.
Background technology
The mono- anti-camera lenses of EOS are the camera lenses of a great market share amount of Canon Inc.'s issue.The camera lens species is more, and
And optics quality is outstanding, it can be widely applied to single electric, micro- one camera and taken pictures and digital video capture.
It is well known that relatively single electric, the micro- one camera price of the price of projector fuselage is more expensive, corresponding camera lens price is then more
Height, therefore film shooting person such as need to frequently change camera lens, high cost limits and creates numeral superior now and regards
Frequency shoots threshold, and the camera lens species being engaged with projector is also less.In order that user has more when shooting film
Camera lens is available, and the adapter ring for making EOS camera lenses adapt to these projectors is occurred in that on the market.
But, current these adapter rings overwhelming majority EOS camera lenses can not be focused and aperture adjustment.Completely not
Smooth fine real-time adjustment aperture and focusing can be realized, the changeable and harsh digital video of adaption demand is just more unable to certainly
It has taken.
Therefore, how to provide one kind can anti-camera lens mono- to EOS carry out independent driving, that is, carry out independent aperture adjustment and right
The switching device of Jiao's control is industry technical problem urgently to be resolved hurrily.
