產品系列說明

  • 大視場
  • C和CS接環鏡頭

可變焦距鏡頭對先前需要多個定焦鏡頭的應用提供彈性的解決方案。只需透過指示的焦距範圍調整來獲得所需視場,然後設定焦點以獲得最佳圖像。Due to the variable focal length range, varifocal lenses are also known as vari-focal, variable-focus, or multi-focal lenses. Varifocal lenses can select the focal length within the specified range like zoom lenses, but unlike a zoom lens focus adjustment is needed after setting of the focal length. 它們具備不同、簡化的光學和機械設計,比變焦鏡頭更具成本效益。The focal length adjustment is typically a middle or rear assembly of elements that slides back and forth, whereas the separate focus adjustment is typically a front cell movement.

#57-680 is a high resolution, low distortion lens for MegaPixel cameras.

注意: CS接環鏡頭與C接口相機不相容。
