My copy Pentacon Auto 1.8 / 50 Multi Coating was taken from a Praktica camera. The lens was available in different versions. There were 3 more versions of the lens before Multi Coating. Pentacon auto 1.8 / 50. In fact, they all differed only in a light redesign of the frame and the method of controlling the diaphragm and enlightenment. In total, as far as I know, there were 4 versions, the model presented in this review is the last of its generation. This is evidenced by the green color of the feet on the focus distance scale.

Highlights you need to know about Pentacon Auto 1.8 / 50 Multi Coating

  1. Manual lens. The designation Auto in this case only means that the diaphragm can be controlled semi-automatically.
  2. The lens has a special MA aperture control method switch. In position M, the aperture is manually controlled. In position A - the diaphragm is controlled in semi-automatic mode. You can focus on fully open, and at the time of descent, the camera through a special aperture pusher will close it to the value set using the aperture ring. Many Soviet lenses like the Helios-44 and Helios-77m-4 lack such an MA switch; they have to manually block the diaphragm pusher when used on digital-mirror cameras.

  3. The maximum aperture value is F1.8- This is a really fast lens. If you have a whale lens, then the maximum aperture on it is only F3.5, which is 3.7 times weaker than that of the Pentacon. Actually big aperture and old optics are famous for their low price.

  4. The lens is made of glass and iron. It stopped being released back in 1978, and it still works. This suggests that the German quality still makes itself felt.

  5. The lens is not standard front filter diameter 49mm. I wanted to put my own on him protective filter 52mm, but it did not fit, it turned out to be a little larger.

  6. The lens has multi-enlightenment. This is an important point when using the old manual optics. Multi-enlightenment helps this Pentacon to tolerate back and side light, as well as give a contrast picture

  8. Focus ring rotates almost 360 degreesand the Pentacon auto 1.8 / 50 Multi coating lens has 33cm minimum focus distance limit. A large and smooth focuser movement allows you to accurately and easily focus. A minimum distance of 33cm helps to remove small objects.

  9. Lens from full-frame cameras. When used on crop, the angle of the field of view will be narrower, and the EGF for crop factor 1.5 will fit 75mm. Pentacon auto 1.8 / 50 Multi coating is a classic fifty dollars, and on crop a fifty dollars is often used for portraiture. If you want to choose a good Soviet portraiture - then look at the “The best Soviet portrait lens"

    Due to watercolor blur, the overall picture does not look sharp

  10. The number of aperture blades is only 6 pieces. They have a metallic sheen and can seriously interfere and add hares when shooting. Closed aperture values ​​produce standard nuts.

Personal impressions

The lens is very compact, sits well on a small SLR camera. It reminds me very much Helios-77m-4. It works fine, the picture is excellent, every photographer should have such a fifty dollars. The main competitor can be considered the Soviet Zenitar 50 / 1.7.

Pentacon auto 1.8 / 50 Multi coating

Image sharp with F1.8. Depth of field is very small at F1.8, it is very, very difficult to get in one's eye. Very good sharpness comes at F2.8. From F2.8 to F11.0, the sharpness is very high. At F16.0, the diffraction on my cropped matrix takes its toll. The most interesting - chromatic aberration very well fixed and they are very small even at 1.8, also, I do not observe the frigging, which on my Nikon 50mm F1.8D AF just awful on F1.8. Distortions and vignetting on crop are also not visible at all. Great color reproduction. The contrast is excellent, the side light Pentacon auto 1.8 / 50 Multi coating tolerates well, in the back it catches a few hares and a noticeable drop in contrast. Bokeh interesting, for an amateur, a little double, somewhat reminiscent of a light watercolor. Unlike Biotars (including Helios-77m-4) it does not twist the background.

Conclusions about Pentacon auto F1.8 50mm Multi Coating

Good manual fifty dollars. Excellent color reproduction, sharpness even at a fully open aperture. The manual control mode and the huge stroke of the focusing ring allow using it on modern digital-mirror cameras without any special difficulties.

  • Karen

    But in fact, the best fifty dollars, which in terms of picture quality is, in my opinion, between the lens of Karl Zeiss and all other fifty dollars - this is Oreston 50mm 1: 1,8

    • Rodion

      Waiting for proofs - how is it different from the pentacon?

  • Karen

    Today I take a picture with both of them, but for now see how they are evaluated at the Pentax forum: This is Oreston

  • Karen

    And this is the Pentacon

  • Karen

    But, as the photos promised, all the photos were taken in RAW and transferred without processing to Lightrum .jpg then each photo was reduced in size by 4 times by reducing the number of pixels on the side of the photo by 2 times. This one was made by the Pentacon.

  • Karen

    This photo was taken by Oreston, as for me, it turned out a little sharper

    • Rodion

      Yes, but no more. The picture is identical. I don’t see the point of overpaying. They evaluate it differently stupidly because of the nameplate effect, no more.

  • Karen

    And this was done with a 55mm Super Reflex lens from Kozina, which I’m taking pictures of now, as I consider it more preferable for portraits (pay attention to the blur of the red car in the background). I hope it is not necessary to add that all 3 photos were taken from a tripod and at the same aperture of 2,0. Z.Y. For the third photo, I slightly pushed the tripod back, for the same scale, t, k, 55mm lens

  • Karen

    Well, for the sake of interest, I took another photo of the same teapot with an Enna Munchen Tele-Ennalyt 135mm 1: 2,8 lens on an open aperture. I hope you are satisfied with the response to your request.

    • Ivan

      Well, actually, of course, 2.0 is not ice everywhere. But the pentacon is not strong in this. In general, it is necessary to note the main thing - that for those interested in these half-legs it is worth looking for exactly M42 and it is in this latest mehversion with color scales as in the photo of acrobatians above. For portlets, it’s easier to immediately turn on 85 105 135 well, but that's another matter. ATP Karen * for a mini-reviewer and pictures.

      • Ivan

        And by the way, about Zeiss - holding in my hands the latest fur carl zeiss 50 f / 1.4 planar for Boot and Nikon and having driven through them a certain number of pictures at one time, for some reason I was not inspired enough to want to spend 800ye on them as they cost then. Yes metal yes brand yes petals yes probably a good picture. But if in direct hands on adjacent diaphragms the practitioners give out about the same with an eye on the price and age, then why should I sculpt a humpbacked one? The main thing is that at the time of its release in 2007 no one was talking about HD and even more so about 4k, so the question was how this optics would behave abroad 24-40 or more megapixels ... So there you go. A practitioner on a full 10-12 hides confidently for which he respects and respects!

  • Ann

    Good day! There is d5100. Which is better suited - Helios 81H or Pentacon 50 1.8 ?? It seems like the first should get up without adapters and have infinity? On the other hand, is there still a question a picture from which will be appreciated higher?

    • B. R. P.

      On Nikon - Helios 81N of course. The site has articles about both Helios and the Pentacon.

  • Kira

    Good afternoon. There was such a problem, focus up to 1,5 m. The same problem with Indstar 50-2. Nikon camera. Has anyone else come across?

    • Rodion

      If you want focus to infinity - buy a canon / sony / pentax. Do not want to change the camera - look for optics with Nikon mount or compatible fully through the ring (Soviet mount N, adapter A, medium format mount B and C for example).

    • Passed by ...

      Kira different rear working segments. None of the technology for m42 thread on Nikon does not fit without alterations. Read the focus on infinity will not. Look for nikkors.

  • Nicholas

    I have a pentacon electric 1.8 background that turns cooler than Geliki 77e (I have three versions of Valdai, Vologda and just 77m) specially compared ... in general, my favorite lens, Oreston, too, but I don’t really ..

  • Ramil

    He inherited this from his father's practice. Really green, very soft on an open hole, but on f4 yesterday I shot a video for a music video in 4K VIA CHINESE BOOSTER FOR $ 100 and was very pleased with the result - https://www.youtube.com/watch?v=zKMsyCzffUE

  • York

    The only thing interesting in this glass is the bokeshka. Everything else is staffing and staffing. On open to the amateur, and on f / 8 all the windows are the same.
    And yes: Oreston from this pentacone differs only in name ...

  • Vova

    Bokeh reminds me a lot of Trioplan. I have a newer version. Black with green and red designations

  • Anatoly

    Hello ! I have such a lens, but for some reason the aperture is blocked. Tell me how to unlock?

    • anonym

      I have the same problem, have you solved your problem?

      • Past the crocodile

        It is solved by disassembling, cleaning, lubricating and if necessary adjustment))).
        The simplest scheme, for the first time if at all from 0, spend 3 hours. To figure it out to the screw. Then with my eyes closed. There is nothing to break there. I sorted out all the series of the model. Favorite glass!) Therefore, do not be afraid and pens ...

  • Galya

    And I need caps on my lens Pentagon 1.8 / 50 mm, tell me which ones are suitable and where you can order., Thanks!

    • Past the crocodile

      There, by default, plastic on the face and M42 are a stub on the tail. If it’s easier to buy an inexpensive uvshnik at 49 before a ban. So you’ll keep your optics and you won’t sow any other food.

  • Michael

    Arkady, what can you say about this lens in comparison with the SMC takumar 55 1.8. Which of them gives an interesting picture?

  • Paul

    Arkady, thanks for your work!
    Will such a lens focus on infinity on the Nikon 5100 with the M42?

    • Arkady Shapoval

      will not be

  • Gregor

    Pentacon 50mm 1.8 MC

  • spitzer

    Does the MS version differ in contrast and backlight from the non-MS version?

  • Irina

    Do not take this resource seriously, here you will not find reasonable and truthful information. ... the diameter of the front filter is 49mm. I wanted to fasten my protective filter to 52mm on it, but it did not fit, it turned out to be a little more.))

  • Serg

    boring bokeh blur

  • Sergei

    A detailed test and sample photos from this lens on Sony full-frame mirrorless cameras have been published.

  • Inna

    Tell me, please, the MA diaphragm control method switch is only in the Auto model? Or does Electric also have a MA switch?

  • Stanislas

    I got this lens, which participated in the review above. Who will tell you how to choose the backlash of the focusing ring?
