Applicant: Sigma Co., Ltd.
Publication number: P2022067732
Application number: P 2020176481
Publication date: 2022-05-09 Title
of invention: Large-diameter zoom lens

PROBLEM TO BE SOLVED: To provide a large-diameter zoom lens which includes a standard range in a variable magnification range, has a small open F value, has a compact overall length, and is capable of high-speed autofocus control.

In the conventional example of the zoom lens, the focus lens group is composed of a large number of lenses, and the weight thereof is large. Therefore, in order to enable high-speed autofocus control, the weight reduction of the focus lens group is insufficient.

When the zoom lens disclosed in Patent Document 1 is applied to a camera equipped with a so-called full-size image sensor, the back focus becomes longer and the overall length becomes longer as the entire optical system becomes larger.

The present invention has been made in view of the above problems of the conventional example, and is a large-diameter zoom lens that includes a standard range in a variable magnification range, a small open F value, a compact overall length, and high-speed autofocus control. The purpose is to obtain.

New TTartisan 50mm F0.95 Announced

By Louis Ferreira | Published: May 6, 2022


The TTartisan 50mm F0.95 can now be found on Amazon.

  • APS-C Normal-length Lens: Normal-length prime is designed for use with Sony E-mount mirrorless digital cameras, providing a 75mm equivalent focal length. It is well-suited to everyday shooting with subjects including portraiture, street, nightscape, landscape, and reportage.
  • Aperture F/0.95: A fast f/0.95 maximum aperture suits working in low-light conditions and also offers great control over the depth of field. Its optical system consists of 8 elements in 6 groups. A 10-blade diaphragm contributes a pleasing out-of-focus quality when working with selective focus techniques.
  • Compact and Vintage Outlook: Weighs about 411g, and the lens is so compact that gives you a very comfortable hand feeling. The silver dents in the lens barrel make the whole lens a more vintage look. The all-metal lens barrel features an engraved depth of field and focuses scales. Additionally, a metal lens mount also offers increased durability between the lens and camera.
  • Friendly Design: Unlike the traditional cap type lens cap, the TTartisan 50mm F0.95 features a creative screw-on metal lens cap, it is quite convenient to mount the lens cap tight with only one spin. The aperture ring is stepped with the right amount of resistance and click, marking on full stops from F/0.95 to F/16.
  • Multi-layer Coating: The multi-layer coating has been applied to individual elements and reduces flare and ghosting in order to produce greater contrast and colour accuracy when working in strong lighting conditions.
