Continuing the Legacy of the First Otus Generation

The Otus ML lenses are engineered to provide exceptional optical performance, revealing details that may not be discernible to the naked eye. These lenses embody the well-regarded ZEISS Look, characterized by sharpness, accurate color reproduction, and a three-dimensional quality.

The apochromatic lens design ensures excellent color fidelity while minimizing chromatic aberrations. Additionally, the aspherical design contributes to virtually distortion-free images, enhancing overall image quality. The ZEISS T* anti-reflective coating further reduces reflections and flare, improving clarity and color accuracy.

From a mechanical standpoint, the Otus ML lenses offer precise manual focus, which enhance the creative and storytelling process. The lenses feature a smooth metal focus ring with a precision helicoid drive, facilitating accurate focusing.

Manual aperture control, equipped with a de-click function for video, allows for seamless adjustments, which can be advantageous in various shooting scenarios.†

Manual focusing is more than a method — it's a way for photographers to connect deeply with their creative power and craftsman-ship, enabling both unparalleled control and artistic freedom. It allows for precise focusing on the center of the image, the story, and emphasizes the exact details that bring the visual idea to life.

The all-metal construction of the Otus ML lenses is designed to endure the demands of professional photography. The compact and portable design is optimized for the latest mirrorless mounts: Sony E, Canon RF, and Nikon Z-Mount, with the 1.4/50 weighing 677g and the 1.4/85 weighing 1,040g.

Clear and precise scales on the lenses enable quick adjustments, ensuring that photographers maintain control over their settings.

The unparalleled excellence of the ZEISS Otus ML lens makes it nearly impossible to find any flaws in the images it captures. Its remarkable sharpness and true-to-life colors are exactly what I need as a professional photographer – to preserve the essence of moments, people, and things as they truly are.

This new lens from ZEISS is simply stunning! Incredibly sharp and precise, with a wonderfully lightweight feel in hand. The fully metal focusing ring? An absolute tactile delight — it’s a joy to use!

The Otus ML lenses are built to perform reliably in challenging conditions. A blue sealing ring protects the camera lens interface from dust and moisture, while additional seals provide protection against splashes.

The lenses are temperature resistant, functioning effectively in environments ranging from -20°C to +55°C. They have also undergone rigorous testing for mechanical, vibration, and shock resistance.

Continuing the legacy of the Otus family, which has been recognized for its low sample variation and outstanding imaging performance since its introduction in 2013, the new Otus ML combines premium optical performance with precise mechanical engineering, optimized for the latest mirrorless mounts.

This positions the Otus ML as a valuable tool for ambitious photographers seeking to combine full, precise control with creative freedom while focusing on the core of their imaging work.

  1. No electric connections to the EF mount?????
    My Zeiss Classic EF mount (15, 21 and 50mm) are all "read" even by the EOS R bodies. Including the focusing help...
    And the Otus not?
  2. According to TDP the 85mm EF mountbOTUS has “The Zeiss Otus does have communication with the camera body (including an electronically controlled aperture)”.
    See: https://www.the-digital-picture.com/Reviews/Zeiss-Otus-85mm-f-1.4-Lens.aspx
    Sure, Zeiss lenses with EF bayonet all have the usual contacts. No reason why the Otus shouldn't have them.
    I think Richard was referring to the Zeiss lenses in Contax/Yashica mount.
    Anyway, it sure would be nice to see them in RF mount.
  3. Back when Otus was released, they were competing against some Canon EF primes that left something to be desired, especially wide open. Just to compare, the Otus 55 f/1.4 vs the EF 50 f/1.2 L, both at f/1.4.

    Now? Canon has really been hitting it out of the park with a lot (most? all?) of their RF lenses. Just compare the Otus 55 f/1.4 to the RF 50 f/1.2 or 50 1.4 VCM.

    I like options, but the quality of the modern lenses is impressive and does not seem to be leaving Zeiss much room to differentiate themselves.

    That said, I'll happily check out what they have to offer. It is not like they get to take my money automatically.

    I might add that the RF 50mm f/1,2 also offers an invaluable advantage, especially wide open: AF!
  5. I also wonder what they could offer.
    2 decades ago, they competed with far inferior lenses from Canon and Co. This has drastically changed, not only with RF, but also with the late EF lenses.
    To be honest, if, as a beginner, I wanted the very best lenses, I'd get the Leica M APOs, Summiluxes and Summicrons or the RF 50 & 85 f/1,2, the RF 100 macro, the RF 135mm, the RF 70-200 etc... Provided I had the necessary $$$$$$$$$$$$$
    Focusing quality and speed matter a lot to me.
    But I'm nevertheless very curious as to what Zeiss will bring...

    An RF 50/1.2 is still not exactly in the league of an Otus.
  7. My guess would that if we are going to get Zeiss lenses for the RF mount they will be similar to how the classic series worked with EF.

    Canon has done a much better job with the RF L lenses, but I'm not sure about the micro contrast that Zeiss is known for.

    Even though I am a Zeiss fanboi, owning several Classics and ZM lenses, I'd anytime trade the alleged microcontrast advantage for the precise RF AF.
    For the Leica M owners reading this post: The Zeiss ZM 25mm f/2,8 is absolutely fantastic, contrast, sharpness, colours, flare resistance. I'd go so far as to qualify it as a perfect lens. Alas, not all of them were mechanically on the same level as the optics. The mount has sometimes a tendency to get loose. So better check before buying...but it's worth it (provided you "6 bit code" it !!!!)
  9. An RF 50/1.2 is still not exactly in the league of an Otus.
    My biggest take away from the article is that the Otus used prices have come way down. Huh. That probably shouldn't be tempting....yet....it would be a bit fun to play around with it vs my RF 50 f/1.2. hmmm.

    At least to me, the article almost perfectly surmises my point, even if one person's impressions are exactly correct, the Zeiss Otus 55 f/1.4 is better against 1) flare, 2) with vignetting, and 3) focus breathing. They also bring up color rendition, but that did not make the top 3 list for whatever reason. Seems to indicate resolution is a push. Yet, despite these, they still carry the EOS-R and RF 50 f/1.2 when they take a "second bag" with them for "easy" shooting when they do not feel inclined to use a "proper camera". Which I read that even to someone that previously owned and clearly prefers the Otus (with 5DRs), the RF 50 f/1.2 (with EOS-R) still meets their standards, at least part of the time.

    There will always be people willing to pay extra for a specific feature.

    I am making an assumption that whatever Zeiss does will have a similar 2x-3x higher price point, similar to the Otus vs "L" 10-15 years ago. Back then, the Otus was clearly better in a number of ways. Yet at that price point even back then with the advantages, I think only a small group of people actually made that investment. If Zeiss comes out with a $5-7k lens even with better flare, vignetting and focus breathing, I would not expect it to sell well. If they come out with a $2-3k lens that is better...then yes, I suspect it will have a reasonable, yet likely smallish (no-AF) market.

    Agreed, if you use af a lot that's a big con of Zeiss glass. I shoot mostly landscape so I'm manual anyway most of the time.

    The EF versions of the Otus line has full electronics, just no AF. There even is a persistent rumour that Zeiss one of the very few companies that managed to get an actual license from Canon for EF.

    I also mostly shoot landscapes. MF lenses can indeed be focused very precisely using the loupe function. And usually fast enough.
    But I also photograph in cities, where you often have to focus real fast, if you don't want to get people or cars in your picture. No issue at all with the extremely quick focusing Leica M, much more with MF lenses on a MILF.
    Additionally, wide open (f/1,2 or f/1,4) photography can be very demanding when shooting portraits wit MF lenses. As I wrote, I love Zeiss lenses, but there are some limitations to their use.

    Should this rumour be true, and Zeiss start making RF/AF lenses, I'm all in! 🙂
