    Conventionally, a small and lightweight zoom lens has been proposed which consists of first to fourth lens groups with negative, positive, negative, positive refractive powers arranged in that order from the object side to the image side, and in which the first and fourth lens groups are stationary during zooming and focusing (see Patent Document 1).
  • An object of the present
    invention is to provide an optical device capable of appropriately controlling a drive unit for moving a lens group included in an optical system.
  • During zooming
    , the lens control CPU 106 controls the motor 101 by feedback control using information from the rotation/position sensor 103. At this time, the lens control CPU 106 controls the motor 104 by open loop control in order to correct focus fluctuations that accompany the movement of the second lens group L2.

overview

  • [Publication number] P2024090416
  • [Release date] 2024-07-04
  • [Name of invention] Zoom lens and imaging device
  • [Application date] 2022-12-23
  • [Applicant]

    [Name or company name] Canon Inc.
  • A compact zoom lens including a lightweight vibration isolation group and high optical performance is provided.
  • [Background Art]
    [0002]
    As a zoom lens having high optical performance at a wide angle and capable of high-speed zooming, there is one having a first lens group having negative refractive power that is immovable (fixed) during zooming, a second lens group having positive refractive power, and a rear group, which are arranged in this order from the object side to the image side. Some zoom lenses also have an anti-shake function that corrects image shake by moving a lightweight lens group other than the first lens group in a direction perpendicular to the optical axis.
  • The present
    invention provides a compact zoom lens which has a wide angle, high optical performance over the entire zoom range, and a lightweight vibration isolation group.
