Sony Photography News and Rumors

It’s unlikely that Sony will ever make a 60mm f/1.2 or 80mm f/1.2 lens, but they already have a very nice 50mm f/1.2 on the market and a 85mm f/1.2 is expected in the future that could be based on one of the below designs.

Overview

• [Public number] P2022140076
• [Publication date] 2022-09-26
• [Title of Invention] Imaging Lens and Imaging Device
• [Application date] 2021-03-12
• [Applicant]
  [Identification number] 000002185
  [Name] Sony Group Corporation
• Kind Code: A1 To provide an imaging lens and an imaging apparatus that are small in size and have a large aperture, yet satisfactorily correct various aberrations, and have high optical performance over the entire screen from an object at infinity to a short distance object.
• [0001]
  The present disclosure relates to an imaging lens having a focusing function and an imaging apparatus equipped with such an imaging lens.
• [0002]
  In recent years, the number of pixels of an image sensor used in an interchangeable lens type digital camera has been increasing. In order to take pictures with higher image quality, there is a demand for an imaging lens with higher descriptive performance. On the other hand, an imaging lens has been proposed in which two lens groups are moved as a focus group.
• [0005]
  An imaging lens that is compact and has a large aperture, yet satisfactorily corrects various aberrations, and has high optical performance over the entire screen from an object at infinity to a short distance object, and an image pickup equipped with such an imaging lens It would be desirable to provide a device.
