Have you wondered why your Nikon SWM lens some focus very fast and some focus very slow. I have this thought long time ago but just can not get the information. Nikon does not tell you all the truth of the Silent Wave Motor. I have gathered some information of the Nikon AFS SWM Silent Wave Motor to share with all.
There are two types AFS SWM used in the Nikon lens. One is used the mini DC motor to drive the gear and rotate the focus. It is a cheap and small type of DC motor. It can be found in the children toy. It is small in size and the focus is slow.
The other type is called Ring-type of Silent Wave Motor. It is big in size fixed around the lens body. The focus is very fast and it is expensive. Nikon should not call the first type SWM, it is totally different type of motor use as compare to the Ring-Type motor. It should give a different name to differentia the two. May be it should call DCM and SWM.
It is not difficult to tell which lens use the Ring-Type motor, just look at the contacts point at the end of the lens. Ten contacts points mean it is Ring-Type motor use. Eight contacts point mean it is mini DC motor use. Another ways to check is to bring your lens close to you ear and listen the rotating sound while pressing the shutter switch. You will hear the different. Similarly Canon also uses two type of focus motor.
