Auto mamiya / sekor 1 review: 1,4 f = 55mm

Many thanks to Vladimir Korogodin for the opportunity to review the Auto mamiya / sekor 1: 1,4 f = 55mm lens sent I have a lens from another area.

Review Auto mamiya / sekor 1: 1,4 f = 55mm. Lens on a Canon 350D.

Review Auto mamiya / sekor 1: 1,4 f = 55mm. Lens on Canon 350D.

Auto mamiya / sekor 1: 1,4 f = 55mm is another legendary Japanese lens. Almost 55 mm, its 50 mm focal length is not very noticeable compared to the usual 5 mm. But I see a situation that even the added 1mm focal length plays a role in the price of the lens. Auto mamiya / sekor 1,4: 55 f = XNUMXmm is now quite expensive, not everyone can afford such a luxury, but it's worth it - the lens is very good in all other respects.

Front lens enlightenment

Front lens enlightenment

The lens is well made, the focus ring is metal, like the rest of the lens barrel. The lens is weighty, the diameter of the front filter is 55 mm. When focusing, the front lens does not rotate, the focusing ring moves 270 degrees, the MDF is 45 cm.It's a pity, but the lens has only 6 blackened aperture blades and such a legendary lens gives ordinary nuts in the out-of-focus area (example). The lens has a blinking aperture device and an 'M <-> A' switch to select its mode of operation.

Sample Photos

Sample photos taken with Canon 350D and adapter M42-Canon without chip. On Canon APS-C 1.6X crop EGF The lens is 88mm, the lens can easily take portraits. At F / 1.4, it is very difficult to get into sharpness. The lens itself is sharp and contrasty.

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 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, Nikon F) it is necessary to use adapters with a corrective lens, which allows correct focusing at all focusing distances. For any mirrorless camera, such a lens is not needed, and the adapter is a simple decorated hollow metal tube with an appropriate mount.

Personal experience

For several days in a row I used two lenses with excellent bokeh, Auto mamiya / secor 1: 1,4 f = 55mm and Asahi OPT. CO., SMC Takumar 1: 1.4 / 50 MF, I liked Takumara's drawing more. An attentive reader noticed that one of the three pictures in the header of my blog (the top header that changes) is just Auto mamiya / sekor 1: 1,4 f = 55mm.

Two legendary lenses

Auto mamiya / sekor 1: 1,4 f = 55mm is a very good Japanese aperture fifty. I want to highlight the excellent build and excellent design of the lens. You can find many similar lenses, for example, Auto Sears 1: 1.4 f = 55mm.

Comments: 54, on the topic: Review Auto mamiya / secor 1: 1,4 f = 55mm

  • Lynx

    very ... unusual pattern. Feeling like a cross between helios and jupiter 37.

  • Copycat

    For some reason, the feeling that the lens is soaping ..

    • Arkady Shapoval

      This is only a omission due to small depth of field,

  • Andrei

    This lens also has a background radiation!
    Somehow I was going to purchase this subject, but it was very competent and responsible (I bought more than one lens from him), the seller did not advise me precisely because of the background.

    • Razor

      This is how the opinion of uneducated people generates fear, when the ambiguity of concepts causes a reluctance to understand the situation, and the denial of the very fact of the existence of another explanation allows you to mislead new participants in the information exchange process, ultimately developing stereotypical thinking: for example, radiation as something deadly ...

      Everything is relative.

      The assertion that this lens has ionizing radiation is generally true, and with the help of a device for measuring the power of such radiation, one can verify this.

      Yes, the design of this device uses, among other components, a substance that is radioactive. Yes, some nuclei in the composition of its atoms are in the process of natural spontaneous decay. Yes, this is accompanied by the emission of alpha particles.

      Suppose it became known that they have a monstrous speed - tens of thousands of kilometers per second. Moreover, they can damage the cells of living organisms. What conclusion can be drawn from these data? Correctly. Radiation can be dangerous.

      This statement is absolutely true. The following statements are also true: the glass of this lens can be dangerous, the glass can be dangerous, the lens can be dangerous. Even a camera can be dangerous. Depending on the situation.

      And for further conclusions more information is required. So, for example, you can consider the situation in which the lens is used for its intended purpose, namely: to obtain an image, being mounted on the camera. Here it must be added that alpha particles are quite heavy, have a short range and quickly lose energy at a small distance from the source. Since they can be effectively retained by a small layer of air and even the outer layer of the skin, external radiation is quite harmless, and can be dangerous only when ingested.

      Thus, there is no significant reason to refuse to use such devices, on the basis of only one fact that it can be a danger that arises under certain conditions. The intended use is intended.

      Of course, you can consider various options for unfair use that go beyond common sense, and many of them will be dangerous. And then you can even come to a completely meaningful logical conclusion: everything can be dangerous. At first glance, this statement may seem absurd, but one cannot deny the possibility of breaking the lens and eating parts of it? True, with such a development of events, the influence of radiation can probably not even be considered: most likely, the body will cease its activity even before a sufficient dose of radiation is distributed so that its organs are affected by radiation sickness.

      But if you are looking for a lens that can be attached with a rear lens to the body of a living creature for a long time, then I would advise you to choose another model. Again, it depends on the end goals. After all, everything is relative.

      PS: By the way, it is worth noting that natural products that we eat also contain radioactive isotopes to some extent. For example, a typical medium-sized banana contains Potassium-40, which has about the same activity as five milligrams of Thorium-232, the oxide of which you can find in one of your lenses. And it doesn't matter that the types of decay in this case are different - after all, you call all these amazing processes the same - RADIATION.

  • Nat

    Oh my god, I now have a Pentax Asahi 1.4 SMC Takumar on a table 20cm from me ... what should I do? :(

    “In any case, you are already irradiated, so there is not much you can do.” Just take it as a fact and bury it at a depth of 2m in a place where there are no people. Then make sure that no one will ever go into your room and touch your table. Then, given that you are already irradiated anyway, it might be a good idea to fly to Fukushima and help the children cope with the disaster - this will be your contribution to the safety of future generations, your action will benefit the entire human race.

      other lists also included Zenithar M 50 / 1,7, as containing lanthanum glass
      lanthanum is a heavy rare earth metal that does not radiate, for the most part, the fraction of its radioactive isotope, as far as I remember, is hundredths of a percent, so I'm not afraid of my I61ls, I61ld, and Zenitar m 50 / 1,7, but 50-60 years old Thorium Japanese (like Takumara 50 / 1,4) I am afraid, somewhere infa flashed, that at this age they already begin to fonder with beta, which is not gut

    • Novel

      "Industar 61 L / Z MC (L is for Lantan - radioactive element)" - maybe L - Lytkarino

  • volodymyr

    bad food: why should you have * active maki buti radioactive? through recent prizes in japan tsunami?


      Look for the type "takumar phonit" on YouTube. Thorium in enlightenment. Especially the rear lens. There is no gamma radiation, but naf it is necessary, there are also decent glasses that do not glow, for example, the West German Zeiss. But if you have already given birth to all children in your life, you can try these glasses :)

  • Nick

    yes konesh nonsense all these speculations about radiation. The Japanese would not make such products, which obviously could harm citizens)

    • Denis

      About radiation, this is not nonsense and not speculation, but a real fact. In those days, the effect of radiation on the body was not studied enough, and such doses of radiation were not taken into account at all. That’s why they made radioactive enlightenments, constantly glowing scales of devices and even watches, etc.
      The watch, by the way, was worn for many years, and no one died of it. Up to certain doses, the body itself manages radiation, another thing is whether it is worth checking.

    • Arkady Shapoval

      It is necessary to take into account the fact that these lenses were made 50-60 years ago, then much less attention was paid to this issue.

  • Ivan

    I liked the color rendering of this lens. Especially in the photo with the forest - beautiful nice colors. And 4th with apricots, also liked.

  • nukemall

    This is a variation of Cosinon 55 / 1.4 with a slightly changed appearance, a common thing for ODM contracts. Mamiya first ordered lenses for 35mm cameras from Tomioka, but then they either didn’t agree on the price, or Yashica interfered, because they ordered outwardly similar ones from Cosina. Some details see here:

  • Yuriy75

    Sorry for the subjective opinion, but for such a picture quality I would not pay more than Helios 44-2 costs. In my opinion, the legendary character is greatly exaggerated; it’s worth to hammer a collection with such junk only for reasons of museum value no more.

    • Arkady Shapoval

      Tastes differ.

    • nukemall

      But stupid Americans (tm) from such lenses violently orgasm. Any "flat-backed" 55 / 1.4 is declared a product of the Tomioka company, "the same Tomioka that made the Japanese cases for the contax boxes." The quality of the picture they do not care - the flowers-twigs on any glass are beautifully obtained.

      • Slider

        “Stupid Americans” (c) sell the Soviet “Amateur” for more than 200 bucks :) Moreover, one of the most famous American photo shops sells.

  • Michael

    Hello! And what is his activity? Even if it fonit, there is nothing wrong with it, provided that some values ​​are not exceeded. Just measure and compare with the standards (in the Russian Federation this is a document called NRB-99) I’m working at the NPP myself, I’m still alive :) Sincerely, regular reader.

  • R'RёS,R ° F "RёR№

    Today I took my mother (absolutely the same as in the review) from the laboratory for environmental protection and radiation monitoring. The result of the examination made me a little distorted ... The intensity of the GAMMA rays, which I did not expect to see there, at least in that amount, at a distance of 50mm from the lenses 2,4mSv / h! Not so little, agree! The intensity of beta and alpha is small, as many have not said. But what is already there is quite dangerous, especially given the close proximity to the eyeball and the thyroid gland. Experts said that such a thing cannot be used in everyday life, unambiguously.

    • Artyom

      Then you can give it to me: D

    • anonym

      it turns out that in an hour we received as much radiation as in a year ...

  • R'RёS,R ° F "RёR№

    I exchanged a couple of Soviet medium format players. The person who took about the activity in the course. He said that he did not care.

  • Andrei

    The lens is about nothing ... 1.4 is not working - it is very soft ... Bokeh? ... nothing special. Sharpness is really good all over the frame, not just in the center like scoops.
    In your reviews I come across the second puncture. The first one was Nikkor 18-200 VR. This is generally a complete POC. The lens is so blurry that recommending it to someone…. Lucky got rid of him.

    I use my mother on Sony NEX 6. The lens is not worth the money (I bought for 50 cu) !!!
    In general, I will sell and buy Helios 81H + an adapter for Nikon F. On the 81st, the warmest memories and cool photos have remained since Nikon.

    • Perі

      Qi photo zroblenі Helios 81N?

  • Pacman

    These cameras use the very common M42 universal screw mount, also called the Pentax screw mount. The only odd part is that some of my Pentax lenses won't fit, because a lug on the back of the Pentax brand lenses hits something inside the Mamiya and prevents screwing in all the way.

  • Karen

    I've been using Cosina's Super Reflecta lens for 5 years already. There are both positive qualities and disadvantages. In addition to the luminosity and artistic picture and pleasant bokeh, I will note the fact that already at 1,6 the lens is working, at 1,4 it is very soft. Here I took a couple of pictures for clarity, cut out and left only the kettle: the first photo is 1,4 - the second is 1,6, the clothesline for drying clothes is also 1,6. Among the shortcomings, I can mention chromatic oberations, which are especially noticeable on the white metal strip for fastening ropes.

  • Karen


  • Karen


  • Karen

    f 1: 1,6

    • Vania

      Honestly, I would not say that at 1.6 he is a worker. Well, for me, for example.
      And there are pictures on 2; 2.8?

      • Karen

        Perhaps you do not take into account the fact that this is just a clipping from the center, but this is how the whole frame looks. Tomorrow I take a special photo for 2,0, because I only shot 1,6 with this lens

        • Vania

          Yes, that's right, I missed this fact.
          But still soft for me. Only for very specific scenes I would venture to use.

          • Karen

            But as promised, I took a picture of the same kettle on aperture 2,0

            • Vania

              Yes, 2 excellent!

              • Karen

                And here is a photo at aperture of 2,8 - in my opinion it turned out very sharp for a portrait

  • Karen

    And his clipping, in my opinion at 2,0, is very sharp, but for portraits I still think 1,6 is preferable.

  • anonym

    All photos are not clear on what aperture is taken! But the shutter speed is indicated, why the heck is not clear!

    • Arkady Shapoval

      Everything is very simple, an experienced photographer for shutter speed and ISO will approximately recognize the aperture. Unfortunately, with manual lenses, recording all aperture values ​​is very difficult.

  • Fedka

    The lens is no sharper than the Zenith M 50 1.7, but this one has a picture, unlike the Zenith!

    • anonym

      Only this one begins to sharpen with 2, judging by the Karen pics.
      Well, drawing ... for an amateur, gel44 can also.

    • Rodion

      IMHO, out of 50 / 1.4 it’s worth only a takumar, but it, the dog, on the T-foot is very dark due to thorium. Of course, somehow this is corrected with the help of UV, but I honestly do not understand the mechanism of repair of the glass structure under such irradiation.

      • Rodion

        Naturally, I'm talking about glasses of the price category up to $ 120-150, because the CZ 50 / 1.4 T * will, for example, be even better.

      • Novel

        There, not only UV is suitable, generally any radiation, including the visible spectrum. Stupidly under the sun, you can set or LEDs (not UV). And the effect just manifests itself after the glass is in the dark. A few months outside the cabinet, a month under the sun or any directional LED emitter corrects everything.

  • Pacifist

    Greetings from snowy Siberia;)
    Guys, if you cast aside its historical value, than it is better than the modern Chinese. For example, this 7artisans 55 / 1.4. Soaps on the open, but the Chinese diaphragm has 14 blades and you can also get an interesting picture.

    PS I don’t want to prove anything to anyone, it's just interesting. The worse the new Chinese versus the old Japanese.

    • Rodion

      So this Chinese is on the BZK, no?

      • Pacifist

        How not? Of course, I use it on Fujik.

        • Michael

          Well, that's worse. BZK needed)

  • J. Taysaev.

    I have Porst color Reflex 50 1.4. In fact, this is the same lens. I checked it with my household radiometer (Radex), showed 6 millisievert, the same as in the apartment. That is, it is equal to the background.
    By the way, it is sharper than Helios and Jupiters and the drawing is more interesting (I generally keep quiet about the quality), and the fact that the software is 2.0 and especially 1.4 is, on the contrary, good, sometimes it is necessary for artistic design, especially for a woman's portrait. And who needs to be sharper, no one bothers to clamp the diaphragm and then it will be sharper than any Soviet fifty dollars, but perhaps Zenitar 1.2 is sharper, so it is much more expensive.
