Sigma Lens Patents Found For Sigma 17-40mm f/4 OS and Sigma 18-50mm F2.8-4 OS

By Louis Ferreira | Published: October 17, 2022


Patent application for optical systems such as Sigma “18-50mm F2.8-4 OS” and “17-40mm F4 OS”

Overview

  • [Public number] P2022158386
  • [Release date] 2022-10-17
  • [Title of Invention] Imaging Optical System
  • [Application date] 2021-04-02
  • [Applicant]
    [Identification number] 000131326
    [Name] Sigma Corporation
  • Kind Code: A1 A compact image forming optical system having a small open F value over the entire zoom range is provided.
  • 2. Description of the Related Art
    In recent years, a so-called mirrorless camera, which eliminates a quick-return mirror that is arranged between an imaging optical system and an imaging device and guides light rays to a finder optical system, has become popular. Since the body of the mirrorless camera has been downsized by eliminating the mirror, downsizing of the imaging optical system is required accordingly. There is also a demand for a large-aperture zoom lens with a small open F value over the entire zoom range.
  • [0004]
    Patent Document 1 discloses a bright positive lead type zoom lens with an open F number of about 2.8. However, there is a problem that the size of the imaging optical system is large. Also, in Patent Document 2, his zoom lens of positive lead type with a miniaturized imaging optical system is disclosed. However, there is a problem that the open F-number at the telephoto end is about 6.3, which is dark.


Example 1

  • Focal length: 18.60-48.50
  • F-value: 2.92
  • Half angle of view: 79.04-31.24
  • Image height: 14.20
  • Overall length: 91.81-114.15


Example 6

  • Focal length: 18.43-53.40
  • F-value: 2.91-4.00
  • Half angle of view: 80.50-28.42
  • Image height: 14.20
  • Total length: 85.00-110.00


Example 7

  • Focal length: 16.30-38.99
  • F-value: 2.91
  • Half angle of view: 87.23-38.26
  • Image height: 14.20
  • Overall length: 85.01-106.84


Example 8

  • Focal length: 17.45-48.50
  • F-value: 4.11
  • Half angle of view: 83.61-31.16
  • Image height: 14.20
  • Overall length: 80.01-105.10


Example 9

  • Focal length: 23.45-68.00
  • F-value: 2.91
  • Half angle of view: 63.7-22.74
  • Image height: 14.20
  • Total length: 115.01-144.79


Example 10

  • Focal length: 28.50-72.80
  • F-value: 2.92
  • Half angle of view: 79.08-31.60
  • Image height: 21.63
  • Overall length: 135.24-165.37

ON1 2023 Launched

By Louis Ferreira | Published: October 15, 2022


ON1 2023

Portland, OR – September 6, 2022 – ON1, creators of software applications and plugins for photographers, announce the all-new ON1 Photo RAW version 2023 is coming in October. The 2023 version is the most significant update in ON1 Photo RAW’s history. Many new AI-powered features turn traditional photo editing methods on their head.

These new technologies in Photo RAW 2023 take away the steep learning-curve that come with more traditional ways of editing. Photographers no longer have to deal with the tedious methods of masking, layering, brushing, or adjusting when working on specific areas of their photos.

The most incredible new editing tool is Super Select AI. If you can point, you can make edits and adjustments to your photos that would have taken multiple steps and tools in the past. Super Select AI removes the nuisance of learning new tools to achieve the desired editing results. It will allow photographers to point to an area of the photo, such as the sky, people, objects, background, and foreground, and choose a type of effect or enhancement for just that area. Read More »

Sony 7.5-13mm F2.8, 8-14mm F4, and 11-16mm F4 fisheye zoom lenses

Overview

  • [Publication number] P2022155067
  • [Release date] 2022-10-13
  • [Title of Invention] Zoom lens and imaging device
  • [Application date] 2021-03-30
  • [Applicant]
    [Identification number] 000002185
    [Name] Sony Group Corporation
  • A zoom lens that is compact, lightweight, and has high optical performance suitable for shooting moving images, and an imaging apparatus equipped with such a zoom lens are provided.
  • 2. Description of the Related Art
    In recent years, the number of pixels of an image sensor used in an interchangeable lens type digital camera system is rapidly increasing. In order to record higher-definition images, it is necessary not only to increase the number of pixels in the imaging device, but also to improve the imaging performance of the imaging lens. Therefore, there is a demand for an imaging lens that suppresses the occurrence of aberrations. In addition, an increasing number of users are using interchangeable-lens digital camera systems to shoot not only still images but also moving images.
  • The
    zoom lens 1 according to Example 1 is suitable for a so-called full-size (screen size: 36.0 mm×24.0 mm) imaging device. The zoom lens 1 according to Example 1 realizes an equisolid angle projection circular fisheye in the shortest focal length state, and an equidistant projection diagonal fisheye in the longest focal length state.


Example 1

  • Focal Length: 7.55-12.59
  • F-value: 2.90-2.89
  • Half angle of view: 95.00-95.00
  • Image height: 11.30-21.63
  • Total length: 98.26-94.54


Example 2

  • Focal length: 7.50-13.48
  • F-value: 4.09-4.08
  • Half angle of view: 95.00-95.00
  • Image height: 11.30-21.63
  • Overall length: 96.50-103.15


Example 3

  • Focal length: 8.13-14.07
  • F-value: 4.05-4.03
  • Half angle of view: 87.50-87.50
  • Image height: 11.30-21.64
  • Total length: 102.12-98.45


Example 4

  • Focal Length: 11.10-16.00
  • F-value: 4.12-4.12
  • Half angle of view: 88.80-88.80
  • Image height: 11.40-21.63
  • Total length: 115.00-95.54
