Abstract

The invention provides a zoom lens and an imaging device using the zoom lens. The zoom lens has a first lens group with positive refractive power, a second lens group with negative refractive power, a third lens group with positive refractive power, a fourth lens group with positive refractive power, and a final lens group with positive refractive power in order from the object side. When zooming from the wide-angle end to the telephoto end, the first lens group is fixed, the second lens group moves to the image plane side, the third lens group is fixed, and the fourth lens group moves. When focusing, the fourth lens group moving, the zoom lens satisfies the following conditional formula (101): 0.20

Description

technical field [0001] The present invention relates to a zoom lens and an imaging device using the zoom lens. Background technique [0002] In movie shooting, shooting is always performed while zooming and focusing. The so-called always zooming and focusing means always moving the lens group of the optical system. When the lens group moves, there is a sliding sound accompanying it. When the sliding sound is loud, it is recorded as noise. Therefore, zoom lenses with reduced moving lens groups have been proposed. [0003] As an example of a zoom lens that reduces movement of lens groups, a zoom lens is proposed in which a first lens group having a positive refractive power, a second lens group having a negative refractive power, and a lens group having a positive refractive power are proposed in order from the object side. The 3rd lens group and the 4th lens group with positive refractive power are composed. When zooming from the wide-angle end to the telephoto end, the 1...
