Tamron 28-100mm F2.8, 35-150mm F2-2.8, and 35-150mm F2.8 Patents Found


Tamron might release an interesting Tamron 28-100mm f/2.8 in the future. The Tamron 35-150mm f/2-2.8, and Tamron 35-150mm f/2.8 probably are related to the slightly different Tamron 35-150mm f/2-2.8 Di III VXD.

  • Applicant: Tamron Co., Ltd.
    Publication number: P2023004721
    Application number: P 2021106602
    Publication date: 2023-01-17Title
    of invention: Zoom lens and imaging device
  • Kind Code: A1 To provide a zoom lens that has a large aperture ratio, is compact overall, and has excellent optical performance, and an imaging apparatus that includes the zoom lens.
  • There is a strong market demand for a zoom lens that has a large aperture ratio and high optical performance in any imaging device.
  • In order to obtain a zoom lens with a small F-number and high optical performance, it is necessary to satisfactorily correct various aberrations caused by increasing the aperture ratio.
  • When moving images are captured using contrast AF or tracking AF, there is a phenomenon in which the size of the subject on the imaging surface changes as the focus group moves. When the change in image magnification due to such movement of the focus group is large, the photographer who observes the live view image feels uncomfortable.
  • According to the present invention, it is possible to provide a zoom lens that has a large aperture ratio, is compact overall, and has excellent optical performance, and an imaging apparatus having the zoom lens.
