    Hello! People, you can tell what kind of mount it is. It is installed on the Pentecon 135 / 2,8. I assume that this is Praktica B, but there are doubts, since I did not find the image on the network, as on my copy. I want to find an adapter for NEX, but the second end has not yet been able to determine.

    Thank you Arkady for your work, I really like your site. I have Vivitar 135 2.8 (6 petals) in perfect condition, which I am very happy with (I use for portraits). Yes, I think it can change to the Pentacon, maybe it will be even better. Do you think there is a big difference in terms of picture?

    Thank you Arkady for your work and useful site! I have Vivitar 135 2.8 in perfect condition (6 petals), I use it for portraits. Do you think it's worth changing to Pentacon? In terms of bokeh and pictures, does it make sense to change?

      I answer myself after changing my Vivitar 135 2.8 to Pentacon 135 2.8 Pre-set. Pentacon paints a softer background like watercolor or oil! Afraid of more backlight but not critical. Vivitar is excellent for its money, but draws nuts on covered diaphragms. In general, I am glad that I changed it to Pentacon.

    Thanks for the reviews! I read all three of them. They inspire confidence when you think whether to make a purchase. I thought and bought just such a version in very good condition. He has done ten test frames so far. A sharp, acceptable contrast, a kind of color rendition. Like, especially considering the price.

    Good day, Arkady. Thanks for your review !!! I bought this lens exactly. I bought an M42 / Fmount adapter with a lens for it, since I shoot by Nikon. The quality is not bad, but leaves much to be desired ...
    There is a question: is it possible to do without a lens and have infinity? Someone writes about KP / AN, someone writes about macro ring Nr1 ...
    Which of this (or something else) really helps get rid of the lens?

        Thanks for the answer! I'll think. Even with a lens, it’s good, but without it it’s just wonderful, and this despite the fact that in the manual, on the crop, from afar.

      I don’t understand why it is necessary to have infinity on a portrait lens, I would put an adapter without a lens. About the lenses they wrote that they spoil the sharpness

    I would like to see a monster boke. But this model gives a flat soap. I call him Tamronovsky :)

      Even though they are optically the same. That's how PR and the number of aperture blades affects the perception of Tamron flat soap)

    Pentacon Electric 135mm f2.8 - aperture not working.
    If you come across such a lens with problems “for a penny” - you will not regret it. Of course, if your hands and head are in place, you can figure out how to fix it. The Germans there stirred up such mechanics that even me, a well-worn man, felt uneasy. I was not able to adjust the work of the diaphragm - it sometimes closed to the middle or did not close at all.
    It was a pity to throw such a beautiful glass. So I ventured:
    1) I threw away all the electronics, along with all the pieces of iron attached to the back cover.
    2) I unscrewed the triangular piece of iron from the aperture control ring.
    3) I put a tube with a hole in the side of some old telescopic antenna onto the diaphragm control pin.
    4) I connected this tube-cylinder with the remaining piece of iron on the diaphragm control ring, and now the diaphragm pin freely walks up and down this channel when the focus changes. By the way, I tied the tube to the diaphragm control ring with some kind of spring, which I unscrewed into the slots below))))
    Yes, aesthetically the diaphragm dial numbers do not match, but it works like in the good Helios without knowing the glitches. So, my friends.

      Hello Rustam! I have a Canon. I bought a Soligor 135 mm 2,8. Super) In the course, a copy of Pentacon Electric 135mm f2.8. Aperture stands at 2.8 Ring spinning petals no. What to do? Maybe I don’t understand something? A nameplate sticks out in the tail, maybe it's in it?

        Perhaps some kind of breakdown, maybe the aperture mode switch on the lens is on A.

    Good day. There are 2 lenses “Pentacon practicar 1: 2.8 f = 28mm MC” and “Pentacon auto 2.8 / 135MC”. Who knows a good specialist in Kiev to remake it on the Nikon D3100? Thanks in advance.

    The author is immensely respected for the professionalism and consistency of presentation. Thanks to this, I changed my mind about selling this lens, and will try to use it on modern digital cameras. He's not particularly advanced (Canon EOS 50D), but I'm not a pro, but an amateur, and for those resources where I post my photos, he is enough for the eyes. Thanks again.

      There is infinity, too chromatite for astrophoto, use J37A.

    I tried this lens today. In terms of quality, I did not notice much difference with Jupiter 37A. For me, both are good. Perhaps it blurs the background a little more when open. Of the minuses - the same sharpness ring. I did not find any more comments. Bye. Here is a photo, shot in RAW, so with processing. And with bad lenses, processing will not help.

    Today, at a flea market, I took a dead man for a symbolic price. Outbid of course it's pipets. There was not enough registration - almost new, my grandfather used it. The glass has seen a very bad life. Let me think I'll just play with the constructor. Broken muzzle completely. The frame and hood are wrinkled. He lay with the former owner in dampness, rusted, the lenses are cloudy. Dismantled, shook out the remains of a rotten diaphragm, washed off the fungus and dirt. I slightly leveled and grinded off the broken frame to remove the rings and pull out the lens. Completely overhauled the mechanics. Collected. It seems to have revived a little. Now the truth is only an open hole at 2.8, but
    the picture is good. Enlightenment, oddly enough, did not suffer. Cutting. A little sharper and more contrast than 37 Jupiter. Thoughts flashed a little - ashamed of us. Germany was defeated at 45. They took away all the developments. And after a few years they again did a lot better than ours and continued in the same spirit. And our production still remained there, and even managed to bend

    Hello. I bought Praktica, they gave Prakticar 135 f2.8 to the standard lens. The joy subsided a little from the inscription made in Korea. As I would like the GDR. I did not find information about it. It looks exactly like German. Don't tell me a story?

      And show me. If Korea is samyang old it is. It should be much worse, but it seems that it should not look exactly the same.

    I have a Jupiter-37A, a good copy, I'm happy with it. Should I buy Tair-11A or Pentacon? Moreover, it will be necessary to look for a new thread for a light filter, and Jupiter M52x0,75 already has everything. 3,5 and 2,8 is not critical, because I often shoot at 5,6.

    Greetings. I once bought one of these inexpensively, I’ve been taking photographs for a while, and now I’m puzzled about attaching a polarizer to it... How can this be done if the built-in lens hood sticks out noticeably in the sheathed mode?

      Try screwing on an empty frame from a Soviet filter, then a polarizer.
