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 dedicated MA aperture control switch. In the M position, the diaphragm is manually controlled. In position A, the diaphragm is controlled in a semi-automatic mode. You can focus on the fully open, and at the time of release, the camera through a special diaphragm pusher will close it to the value set using the aperture ring. Many Soviet lenses, like Helios-44 and Helios-77m-4, lack such an M-A switch, they have to manually block the diaphragm pusher when used on digital-SLR 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.

  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 correspond to 75mm. Pentacon auto 1.8 / 50 Multi coating is a classic fifty dollars, and fifty dollars on a crop are very often used for portraits. If you want to choose a good Soviet portrait painter, then look at the section “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 diaphragm 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.
