FangDou lens. Manufacturers in the Digital Camera Battery low speed in order to improve the shutter, handheld camera taking pictures of the success rate, so the design FangDou mechanism. Have this kind of mechanism, even if security shutter reduce 2 to 3 class can also clap a clear picture. For example: in the security shutter is 1/60 seconds, if lens is FangDou lens, so even if the shutter speed decreased to 1/15 SEC or 1/8 SEC also can shoot the clear pictures.
Generally speaking FangDou mechanism is composed of two groups of sensors, and correct image of the optical lenses. When sensors canon nb-2l battery induction to lens vibration, will judge is up and down around or shock, then drive corrective lenses correction of the same direction, can reduce the degree of fuzzy pictures.
Lens has no vibration, the light accurately focused on sensitive components. Camera shake down, the light cannot accurately focused on photosensitive Canon EOS 1100D Battery components, produced as poor, blurry images. The function of hand shake, corrective lenses and follow the lens vibration direction correction, the correction that like poor after become smaller, fuzzy reduced.
