Overview of Jupiter-21M 4/200

Jupiter-21M 4/200 and Jupiter-21A 4/200 - outwardly two different lenses, their bodies are very different. The only thing that remains the same with lenses is optical circuit, and the color of the DOF indicators. Jupiter-21M 4/200 is a newer modification that was produced at the Vologda plant, version Jupiter-21A 4/200 was produced at the Krasnogorsk plant. There are versions with the spelling of the name in Latin: Jupiter-21M, Jupiter-21A. About Jupiter-21A and Jupiter-21M is well described on the website of Sergei Elizarov here.

Jupiter-21M 4/200 can be much more often seen in the hands of amateur photographers than the more rare Jupiter-21A... I used two versions and got the impression that the 'M' version is not that much inferior to the 'A' version. The 'M' in the name of the lens refers to the blinking diaphragm and M42 mounting thread, and the 'A' refers to the replaceable shank. Generally 'A' lenses are considered more successful modifications than others.

The focusing ring of Jupiter-21M 4/200 is very smooth, rotates approximately 270 degrees, while the front lens does not rotate, and the lens trunk is noticeably lengthened. When focusing, the entire lens unit moves. The minimum focusing distance is 1.8m, versus 1.7m for the 'A' version. Sighting is pleasant and easy.

The weight of the Jupiter-21M 4/200 lens has increased to 980 g, compared to 740 g for the 'A' version. Jupiter-21M has a built-in retractable hood, the hood is metallic and short. The diameter of the lens hood is 67mm, and the diameter of the front filter is 58mm. The lens that is presented in this review is numbered 83018196.

Jupiter-21M has an automatic blinking aperture. The lens has a special ring that can be used to switch to manual 'M' or automatic 'A' aperture control. The aperture ring itself is in the middle of the lens, you can only set fixed F-numbers from F / 4-F / 22. The 'A' version had a smooth aperture change and an additional ring for its preset. Also, the number of diaphragm blades was cut off for Jupiter-21M, now they have become 8 pieces, compared to 10 in the 'A' version. When the aperture is closed down to f / 8, the lens produces nuts with serrated in the out-of-focus area (the so-called circular saw, see for yourself). The 'A' version has smoother circles in the out-of-focus area on closed diaphragms.

How to use with modern cameras?

Lenses with mounting thread M42 (M42 X 1 / 45.5), such as the lens from this review, are very easy to use on almost any modern digital camera (both SLR and mirrorless), for this it is enough to choose the right adapter (adapter). You do not need to carry out any additional steps to modify the lens.

The cheapest adapters can be found at Aliexpress.com... There are adapters (adapters) with a chip that provide more convenience during shooting, usually chips are used to confirm focus and / or metering exposure, and form the correct EXIF. The chip does not affect the image quality in any way.

For some SLR cameras (for example, with the Nikon F-mount), you need to use adapters with a corrective lens, which allows you to focus correctly at all focusing distances. For any mirrorless cameras, such a lens is not needed, and the adapter is a simple decorated hollow metal tube with an appropriate mount.

    It seemed strange to me that with the same data (layout, aperture ratio, optical characteristics), the Yu-21M is heavier and larger than the Yu-21A .. disassembled, removed all unnecessary, it turned out MUCH more compact and, a little easier .. it became much more convenient to hold in your hand. . went further, removed the ENTIRE aperture mechanism, it turned out 3,5 (compared with Vivitar 3,5 / 200 .. with very good sharpness (H.A. does not count), I do not need aperture ..

  • Julia

    Hello. Tell me, is the adapter for Nikon d850 that you offer in the article (with a chip and a lens) suitable?

    • B. R. P.

      Will do.

    • Arkady Shapoval

      Yes, it will do, but on the d850 some better lens is better, look for your native Nikon ai 200/4 (this) is inexpensive.

    • MARAT

      Not suitable, because Nikon D850 is a full-frame device, the adapter will catch the mirror, the owner of the Nikon D610 and the mirror will catch it (exactly the one with the lens). In the same price category there is Telear-N.

      • B. R. P.

        If the adapter is normal, it will fit.

  • Amir

    tell me what can be done?
    canon60d bought a programmable adapter but it only works in live view mode, it gives an error through the peephole, is this an unsuccessful adapter model?
    the second does not focus at infinity, everything blurs, and in the middle it also focuses poorly, it only catches well within 20 meters, is this normal? crop factor 1.6.

    Maybe the lens is just misaligned? Can you tell me what can be tweaked?

    • B. R. P.

      Perhaps the curve adapter, the lens could be disassembled and reassembled incorrectly. What to twist look on YouTube.

  • Stas

    On the Internet, there is an opinion that the corrective lenses of KP / AN adapters do not introduce distortion. Your comments on this matter!

    • Andrei

      Where are the lenses in this adapter? Have you ever held it in your hands before asking a question? I am sure that the “open spaces of the Internet” are somewhere in Russia, where they like to ask questions without delving into their meaning.

    • Arkady Shapoval

      kp a / n goes without a lens, the image does not spoil

  • George

    Hello, I am impressed with your review and results from using this lens. I would like to ask you if this lens can be used in my Fuji HX -1 x mount camera effectively?
    If yes, is it possible to focus to infinity?
    Do you think that this adapter:K&F Concept M42-FX Adapter for M42 Screw Mount Lens to Fujifilm Fuji X Cameras is the proper adapter for this lens?
    Thank you very much.

    • B. R. P.

      Yes, everything will fit. How effective the use of the lens will be more up to you. Of course, more modern lenses are more efficient.

  • Paul

    Good afternoon, whoever, far away, will tell me which adapter with a lens is needed for infinity on Jupiter 21m 4.200, on nikon d3100. There is an adapter with a lens, but it does not fit, I would like to know exactly which one is needed.

    • B. R. P.

      Already suggested. Quote from the review: “NIKON: For Nikon DX / FX cameras, as well as for Fujifilm and Kodak cameras with Nikon F mount, you need an M42-Nikon F adapter, you can buy such an adapter without a lens and a chip here, with a lens without a chip here, with a chip without lens here, with lens and chip here. Why a lens? Why a chip?
      What adapter do you have and what exactly does not fit?

      • Paul

        I figured out the adapter, it didn’t spin with me due to the fact that another adapter from the Vega 11 u (m 39) lens was screwed into it. I put it on jupiter21m but still there is no infinity

        • B. R. P.

          There is no infinity because it is without a lens.

  • Paul

    no lens there is it just not visible in the photo

    • B. R. P.

      Who knows what adapter you have.

  • Jasont Louis

    Hello. Tell me what adapter will be on the Nikon D3200? I am a beginner, I have a Nikon D3200 with 18-55 and I wanted to try Soviet lenses. Helios 81N, Jupiter 37A and 21M which I liked more. Thanks in advance :-D

    • Arkady Shapoval

      In the review, after all, there is a block on adapters.
      NIKON: For Nikon DX / FX cameras, as well as Fujifilm and Kodak cameras with Nikon F mount, you need an M42-Nikon F adapter (there are also links)

  • George

    Hi there.
    I have a Jupiter 21M lens on a Fuji hx1 camera. I really like this lens and I use it effectively in shorter distances, but I can,t focus in infinitive. May be it needs some “intervention” on it.
    Would you like to help me do this.
    Thank you very much.

    • B. R. P.

      Try to choose the right adapter, taking into account the difference in working lengths.

  • George

    Hi there,
    Thank you very much for the quick response.
    I use an k-f adapter m42 fx. Do you know if there is another more specific adapter for the Fuji hx 1?
    Thank you very much

  • Alexey

    good afternoon
    Is it possible to use a Jupiter 21M lens and a Panasonic DMC-FZ20 camera?

    • Arkady Shapoval


  • gtt

    Welcome all!
    Canon 450d + Jupiter-21M (same as in the review).
    Adapter without chip.
    I focus through the viewfinder on a specific object, take a photo and...
    the object in the photo is out of focus, the focus is shifted forward.
    Absolutely the same on 1000d.
    When focusing through the screen, history repeats itself.
    I can't imagine what the problem could be.
    On the nex-c3, the same lens behaves correctly; in focus is exactly what it was focused on.

    • Rodion

      Yes, it cannot be that “through the screen” history is repeating itself at 450d.
      Through JVI - easily. Do “focus bracketing.”
