The Chinese have managed to release a whole brood of various extra-fast F / 0.95 for full-frame cameras. Not all of them give real T / 0.95 (here I am talking about 'T'-steps), sometimes they do not even reach T / 1.4, but they are still very interesting solutions. The optical schematics of such lenses are shown below.

The figure shows the diagrams of the lenses:

  1. TTArtisan 50 / 0.95, only for Leica M. Housing black + silver + 'Silver Black'+'Red Ox 2021 Limited'+' Silver Anodized '. Scheme 11/8. Near 900$
  2. ZHONGYI SPEED MASTER M 50 / 0.95, only for Leica M, black or silver, pattern 11/8. Near 800$
  3. ZHONGYI SPEED MASTER 50 / 0.95, Canon EF only, 12/6 pattern. Near 800$... Fastest lens for full-frame DSLR cameras
  4. ZHONGYI SPEED MASTER III 50 / 0.95, for Sony E, Canon RF, Nikon Z, Leica L, diagram 10/7. Near 800$
  5. BRIGHTIN STAR 50 / 0.95, for Sony E, Canon RF, Nikon Z, Leica L, FujiFilm X, Micro 4/3, scheme 10/9. Near 400$

For example, the original Leica Noctilux-M 50mm f / 0.95 ASPH. costs around $ 13000, original Nikon NIKKOR Z 58mm f / 0.95 S Noct in the region of $ 8000. True, the Chinese brothers, of course, are not so good optically.

    how can I be less than 1? vichny dvigun?

    • Rodion

      Aperture is just the ratio of the pupil diameter to the focal length of the lens, it is limited only by the laws of light refraction.

    • Arkady Shapoval

      You are most likely misunderstanding the numbers F and T. They do not represent the percentage of light transmission, it is only the ratio of the focal to the pupil. They did quite well and 1: 0.7

  • Nikolaj

    Where is Zenitar 50 f0.95?
    Or is it built on one of the above schemes?

    At one time, the "first after Noctylux" was SLR Magic LM-Cine 50 T / 0,95 for M. Leica's fans criticized him, after which the manufacturer switched its production to the "custom-made" mode. Now you can't even order it on the website, but it's a pity - it was more interesting than Mitacon.
