Tamron 15-28mm f/2.8, 24-70mm f/4, and 24-50mm f/2 Patents Found

By Louis Ferreira | Published: December 27, 2023


Most of these patents are probably related to existing lenses from Tamron, but a 24-50mm f/2 zoom could be attractive and maybe even affordable.

Overview

  • [Publication number] P2023181855
  • [Release date] 2023-12-25
  • [Name of the invention] Zoom lens and imaging device
  • [Application date] 2022-06-13
  • [Applicant]
    [Identification number] 000133227
    [Name] Tamron Co., Ltd.
  • [Problem] To provide a zoom lens that is small and has good optical performance.
  • [ Background Art]
    In imaging devices using solid-state image sensors, such as digital cameras and video cameras, the solid-state image sensors have been increasing in number of pixels in recent years, so lens systems have become more sophisticated than before. is required. Further, as cameras become smaller, there is an increasing demand for smaller zoom lenses.
  • [0005]
    Patent Document 1 is a standard large-diameter zoom lens for a so-called mirrorless camera, and since the amount of movement of the first lens group and the second lens group when changing the magnification is large, the total optical length is long, Due to the large change in the axial luminous flux due to the movement of the lens, the lens diameter has also increased, making it difficult to meet the demand for smaller products.
  • [0006]
    Patent Document 2 is a high-power zoom lens for a so-called mirrorless camera. Due to the large amount of movement of the first and second lens groups during zooming, the total optical length is long, and the change in axial luminous flux due to movement during zooming is large, resulting in a large lens diameter. The demand for miniaturization has not been met.
  • [0007]
    Therefore, an object of the present invention is to provide a zoom lens and an imaging device that are compact and have good optical performance.

DPR: Sony a7CR Studio Scene

By Louis Ferreira | Published: December 21, 2023


Sony a7CR:

The Sony a7CR has been added to DPR’s studio scene, but there is a noticeable lack of sharpness in the studio scene. DPR thinks that there might be a difference in the anti-aliasing used on these two cameras, but I wonder if it might be a difference in the IBIS systems. Either way interesting results worth taking a close look at if you are trying to pick between these two cameras.
