可変焦点レンズ
1. Varifocal lensA varifocal lens is a camera lens with variable focal length in which focus changes as focal length changes, as compared to parfocal ("true") zoom lens, which remains in focus as the lens zooms (focal length and magnification change). Many so-called "zoom" lenses, particularly in the case of fixed lens cameras, are actually varifocal lenses.
