  • [Public number] P2023039482
  • [Release date] 2023-03-22
  • [Title of Invention] Optical system and imaging device
  • [Application date] 2021-09-09
  • [Applicant]
    [Identification number] 000133227
    [Name] Tamron Co., Ltd.
  • Kind Code: A1 A compact, lightweight, high-performance optical system and imaging apparatus suitable for a compact imaging system, and having an open Fno greater than 2.0 are provided.
  • 2. Description of the Related Art
    Conventionally, photographing apparatuses using solid-state image sensors, such as digital still cameras and digital video cameras, have been widely used. As the number of pixels of solid-state imaging devices used in these imaging devices increases, optical systems are required to have high resolution performance while maintaining compactness and light weight.
  • [0003]
    Further, as the size of the solid-state imaging device is increased, a large blur is required. Therefore, the optical system requires a large-aperture lens with a shallow depth of field and a brighter aperture Fno than 2.0.

Background of Minolta Vectis interchangeable lens system
The Minolta V-mount was a new AF SLR system (Vectics Series) launched in 1996, which was parallel to Minolta’s famous Alpha A-mount system .

The V-mount provides electronic control of both focus and aperture like what Canon EOS system can do, and offers a compact lens system compatible with APS film, which is slightly smaller than 35mm film(crop factor about 1.4x). All 8 V-mount lenses released were supposed to be high quality for the coming digital camera era, however, these V-mount lenses were only designed to be controlled electronically by the body with motorized focusing drive, which makes them impossible to be used on today’s mirrorless cameras without a proper electronic adapter. With a mechanical adapter, they don’t work and the MF ring simply cannot be turned. This was a significant drawback of these lenses for those who like to use them with the current mirrorless bodies.

This Vectis system has a total of eight lenses, three primes and five zooms as follows:

  • 17mm F3.5
  • 50mm F3.5 Marco 1:2
  • 400mm F8 Reflex
  • 22-80mm F4-5.6
  • 25-150mm F4.5-6.3
  • 28-56mm F4-5.6
  • 56-170mm F4.5-5.6
  • 80-240mm F4.5-5.6 APO

The 17mm F3.5 was introduced along with Minolta’s RD3000, equivalent to a classic 28mm lens.

The 400mm F8 Reflex, which was then designed to autofocus on the Vectis S-1, S100 or RD3000, is now able to autofocus again with the LA-VE2, becoming only the second AF capable mirror lens next to the famous Minolta 500mm Reflex.

In 1996, Minolta realized the design of built-in focus motor, electronic focus ring, electromagnetic aperture, electronic AF switch, and Weather sealing for V series lenses. These designs are not outdated till now. So, LA-VE2 is the best choice for you to try Vectis lenses.
