CROWBAR. Review from the reader Radozhiva

An article about the adaptation of LOMO P-5 F = 100 1: 2 and examples of photos from it, especially for Radozhiva, prepared Vershal Michael.

LOMO P-5 F = 100 1: 2 lens adaptation

LOMO P-5 F = 100 1: 2 lens adaptation

The constant thirst for aperture and the pursuit of artistic bokeh for little money make savvy work to the fullest. That is why interest in old Soviet lenses from cameras, magnifiers, projectors and other optical devices does not run low. For owners of mirrorless mirrors this is a bonanza. For those who "sit" on the DSLR, there are certain restrictions in the case of a small amount of the rear segment of the lenses. For my part, it seemed interesting to me to easily accessible projection lenses, such as, for example, LOMO P-5 100 f / 2. There was a desire to try to adapt them for landing on a Sony Alpha SLT-A37 camera with or without infinity.

What for? To decide whether it's worth bothering at all and investing in the manufacture of more solid homemade products based on projection lens blocks. What's so interesting about these projectors? Excellent "passport" sharpness, not trivial bokeh and high aperture at a penny cost.

A bit of bookkeeping

The first thought, contacting Chinese helicoids, was rejected, because this, I will tell you, is not cheap at all. A Chinese helicoid with the necessary adapters (from 62.5 to M65 + from M65 to M42) is about a hundred dollars.

An option was also considered to choose lenses that could be used as donors, preferably something from the “post-Soviet” one. A really suitable size donor from a mirror meniscus donor with characteristics of 800 f / 8 would cost, well, say, $ 50-70, if you look well.

Both are expensive for the experiment, so my search continued ...

Some theory

Before you start redoing something, you should make sure that the lens you have chosen can in principle “work” on your camera. First: the aspect ratio that will cover the lens. There are different projectors for 35, 16 or 8 mm films - the first one suited me, the second on the crop can give a vignette around the edges, and the third is too small. Second: the rear segment of the lens is the distance from the plane of symmetry of the last lens to the point in space where a sharp image is formed, it is also the focusing of the image at infinity. Roughly speaking, the task is so that the lens unit of the projection projector, in its closest position to the camera mount (or a little further from it), can “finish off” with the formed image to the camera matrix. If the back segment is too small, the image will "hang" somewhere to the matrix, and it is no longer possible to push the lens unit deeper into the camera body. Thus, it will be correct to first find out the rear section of your camera (you can search for the characteristics of both the "carcass" and any lens for your system), and then look for the characteristics of the projector.

LOMO P-5 F = 100 1: 2

In my work I took LOMO P-5 100 f / 2 with the following characteristics:

Frame format: 35 mm.
Lens Type: Aplanat.
Focal length: 100 mm.
Relative aperture: 1:02.
Frame diameter: 62,5 mm.
Lens length: 90 mm.
Back segment: 48 mm.
Light transmission: 90%
Resolution (center / edge): 90/35.

Practical part

On the LOMO P-5 100 f / 2, the rear section is “close to” the Sony A mount (44,5 mm). No locksmith was needed. At the first stage, we used: a Pringles can, an M42-Sony A chip adapter, a piece of thick foam rubber from a technological packaging 10 mm thick, 3M double-sided tape 1 mm thick, strong curved nail scissors and some rubber glue. At the bottom of the can, apply the M42-Sony A adapter as centered as possible, mark the inner hole and carefully cut out the circle with scissors, then make a slot for the bayonet latch pin. We glue the adapter to the bottom of the can with double-sided tape. Next, you need to accurately measure a piece of foam rubber so that it tightly wraps the lens unit with an interference fit. We wrap the lens barrel with foam rubber and carefully insert it into the pot of chips. It turns out a fairly monolithic structure. Finally, cut a hole in the plastic Pringles cover slightly larger than the diameter of the lens unit and close the jar - this solution will fix the foam rubber and prevent it from sliding out together with the lens barrel. Everything! The trial lens with manual (pump) focusing is ready!

LOMO P-5 F = 100 1: 2

However, flaws in the design immediately surfaced. Firstly, the lens unit was reluctant to walk in foam rubber, because in terms of friction this is not an optimal pair, you have to focus with your feet, hands and body, which is not very convenient. In addition, changing the lens to another was fraught with difficulties, you have to take out the lens unit along with the foam rubber, then wrap another lens and shove it back into the jar. Secondly, the bottom of the can is shiny inside, and the walls were, in my case, pink - the color of foam rubber, which is not good, inside the lens should be black. And, thirdly, the lens in this form did not fit on the Sony A37 mount at all - the edge of the can from under the Pringles rested against the beak of the built-in flash. I had to cut off a part of the edge, somewhere in a quarter of a circle, and seal the cut with rubber glue, since in this place the mechanical strength of the already weak bottom of the can was broken, as well as the tightness of the lens.

LOMO P-5 F = 100 1: 2

Further, the homemade product was revised. A circle on the bottom of the can and a rectangle were cut out of dense, but not thick black cardboard in order to twist the tube, which simultaneously separates the lens unit from the foam rubber and “blackens” the inner part of the lens. In addition, since the reaction of people who saw a person with cameras trying to shoot with a can of Pringles was assumed to be ambiguous, it was decided to wrap the body of the can with black duct tape. Thus, the main problems of homemade products, discovered at the first stage, were worked out. The lens unit inside the lens moved much easier (but you had to make sure that it did not fall out), the inside of the lens was made black. The only thing left was to test this design ...

LOMO P-5 F = 100 1: 2

First tests

The expected result for the Aplanat scheme: twisting the background, a sharp center and fast blurring of the corners. Enlightenment is yellow.

LOMO P-5 F = 100 1: 2
LOMO P-5 F = 100 1: 2
LOMO P-5 F = 100 1: 2
LOMO P-5 F = 100 1: 2
LOMO P-5 F = 100 1: 2

Innovation

In fact. Focusing out of a can is a perversion. Good for trial, but absolutely inapplicable in practice! I asked for the idea to insert the projection into the helicoid. One problem is that helicoids of the required diameter cannot be found "for a penny". I had to go for the trick. As donors, it was decided to use ... the now popular souvenir glasses in the form of a lens with a zoom function. The helicoid in them is plastic and with a very small "focusing travel", but nevertheless, it is better than nothing.

The first glass a la Nikon did not fit, with a very decent quality of the helicoid, its diameter in the back did not allow pushing the projector into it, I had to use the purchase as intended - I drink coffee from it at work =)

By the example of this, which has not become a lens, glass can be seen how it is disassembled and how the metal part is twisted from it.

Then a glass of a la Canon with a larger inner diameter of the helicoid was purchased. The projector has thrust itself perfectly into it. The back was cut out as close as possible to the rear lens plane to the bayonet mount, a chip-on adapter with an adapter from the M42 thread to Sony Alpha was mounted on plastic with double-sided tape.

The helicoid in this circle turned out to be quite clumsy. I had to figure out how to build lenses into it and not violate the functionality. Also, the places of friction had to be generously lubricated with Litol. Unfortunately, such a helicoid has no stroke and, as a result, the effective focusing distance is extremely limited - offhand, from 40 to 400 cm, it was not possible to achieve infinity on the DSLR.

Conclusions

Of course, a high-quality helicoid cannot replace a plastic mug. However, let me remind you that in fact, for $ 25, you get your hands on a 100 mm focal lens. with a relative aperture of f / 2. Try to find something with the same characteristics for the same money! There are also a couple of millimeters to move the lens unit, but this is unlikely to allow you to reach infinity. However, the drawing, for my taste, the lens has good, beautiful bokeh, narrow depth of field. I really miss the ability to cover the aperture and smoother focusing. In practice, you have to focus with the body, but for “manual maniacs” this is a familiar thing =)

  • Radmir

    Bravo to the author, really the picture on the lens) is good!

  • Sergei

    A cool photo turned out!

  • Alexander

    Isn’t it better to order a helicoid to a turner, sanded, painted with powder paint?
    If everything is done carefully, it will not be distinguished from the factory one, even drawings are ready on the network.

  • alexey_laa

    I tried to do this, but did not expect to get something suitable for shooting, but more to see what photos would turn out. I put the lens from the slide projector into a plastic tube. The photo turned out to be software, low contrast. I did not experiment further. :)

  • Dim

    Those. Nicam mugs are still much cooler than Caniam - that's what comes out to be tested. Everywhere the same thing, even the Chinese admitted it ☺

  • Igor

    Before you wait for the harvest, you need to plant or plant something. Namely, material. Investments like there over the hill for whom we all chase every day using their equipment. From where in the USSR, especially in Russia there will now be competitive optics and photos. I have somewhere there is a document of the Krasnogorsk Zenit plant, and so they were preparing for release in 2007 two FF SLRs 8 and 7 PPIX. but who destroyed these developments, the question is not complicated. The economic crime of leaders of leading brands, this would reduce the sales of well-known companies, and even the optics on these mirrors should support Nikorov’s glasses.

    • Oleg

      That is, again, someone is to blame

    • Denis

      if they really tried, then they would not have done anything for objective reasons. maximum pulls on a scam. google "belarusian monitor integral"

    • Jury

      The release of Zenith "would reduce the sales of well-known companies" - do not tell my sneakers

      • Obama seducer

        That's what poverty does with photographers :) The Pringles are already ready to shoot weddings. Oh pasans. Dump to Europe or to me in the USA, you will take photos exclusively to Otus and Lake. For a wedding for $ 6000 you will receive cheese and bulldozers crush. True, we have lack of spirituality here, but still it’s better to shoot than at Lomo Prings.

        • anonym

          Everyone here has decent glasses (And not very cheap.). Everyone here has a craving for research and the use of ANY GLASS for photography, but at least a peephole !!! :-) And we will do it always and under any conditions! Because it's interesting ! And often watering cans, some, give the result much more boring and worse than brands without “legendary” backstories. Inquisitiveness of mind and interest in our surroundings, sir. (And yes, you better come to us! :-) We are not badly fed even here! :-)
          ……)

        • Alexander Hedgehog

          happiness is not in the watering can and otus, but in self-realization and understanding that you are at home, around your brothers, and you can do everything here, and who are you in a foreign country, a tourist, a servant or already a mankurt?

  • Ilyas

    • Rodion

      Not soon. In the best case, around the new year.

      • Daemon

        Good luck! Will wait :)

  • Igor

    There is a rule that every disaster has a name and surname, and who brings down the industrial and rural. households and so on, removing competitors, think for yourself. The topic is closed.

    • Denis

      policy is prohibited here. I hope the garbage will be cleaned

    • Oleg

      “Every calamity has a name and surname” - yes there is human stupidity. When a person cannot do something, he comes up with conspiracy theories and enemies. About “Zenith” amused of course. For example, no one bothers Samyang. Take at least the Samyang niche, and then write about the enemies

      • Simon

        :)))) You do not understand anything, the main thing is to find the enemy, there is an enemy there is a great sense ...

    • a lion

      In the USSR, the state had no more enemies, which did not stop in the years 50-70 selling excellent competitive photographic equipment abroad (!). No one bothers the Chinese Xiaomi to release its mirrorless.

      • Vitaliy U

        What “photographic equipment” did the USSR export? Lenses converted from Zeiss? Made from glass exported from Germany? On the German (exported) equipment? Do you know about the history of the “legendary” LOMO camera? This is how new technologies “appeared” in the USSR, and not only in the field of photographic equipment production ... What are you talking about, dear?

        • anonym

          The car was invented by the Germans. And the whole world tore this scheme and began to produce their own. What are you talking about, SER!? Our optics and photographic equipment went on sale worldwide. Millions !!! Had a good reputation. She was even faked. So, you are biased and say absurdity politicized, not looking at reality and facts at all. Listening to you is boring and not interesting. (Tell me how used German machine tools worked FIFTY YEARS, with jewelry tolerances and did not break! That's the same, the machines were ours, our engineers, our glass, our calculations. And where were the Germans all this time? :-) (You voiced delusions. I feel sorry for you, since you are divorced from reality and live in your own invented world of silly delusions.)

          • koba

            Everything is correct. after World War II, almost all patents for optics and not only were opened, everyone could use the existing schemes. First of all, they were used in Japan and in the USA, and in the USSR they were used, some even modified and improved, established the production of glass, and before that there was no time for glass, as some still remember, generally enlightened Europeans came to kill Soviet people, including our ancestors (by the way, the enlightened Germans in those years destroyed more than 20 million Soviet citizens and destroyed almost half of the USSR, and what was exported by right of trophies in exchange for the inflicted many times greater damage to the USSR (!!!) - the USA and England they were also taken out and no less! - this was not even 1% of the damage caused). So, for example, the design of the Leica camera, as successful at that time, was adopted by more than 150 manufacturers all over the world, but for some reason no one talks about it, all at once about the USSR. There is even a catalog of Leica copies, but in my opinion it's not worth talking about at all - everything that is advanced and excellent, regardless of which country it is from, has the right to become the property of all mankind after a certain time, when the patent terms expire, usually 25 years. Everyone created something of value, and they sold it too. The USSR also exported goods, and if the Khrushchevites had not inflicted a targeted economic blow on the USSR economy in order to destroy it, and then all the others did the same, then, according to Nixon himself, by 1960 every third product in the world would bear the stigma “Made in USSR". This is what the Chinese did, everyone can see - they followed the Stalinist model of the economy, that is, they did everything to build heavy industry as the basis of the foundations of the entire real economy and production, it took more than 40 years, but there was nothing without him, and then they did that what they did, and now the Japanese themselves are importing tons of Chinese optical glasses, and I recently bought a new wide-angle lens for $ 95. Admiring other people's achievements is good, but spitting in your own garden and signing your own worthlessness is always bad.

        • Oleg

          The Germans are everywhere from cars to lenses. And where there are no Germans, there are Japanese. In general, you need to attribute the letter G or D to Helios-44-2, like in Nikon. Such a clever marketing ploy to increase sales. You come to a store like this and say: “Give me a Helios-44-2G” Do not take it to heart - these are reflections on the current rebranding of old Soviet lenses. All schemes of Soviet lenses are well known to everyone: tesars, planars, sonnars, distagons. As well as the FED was a copy of Leica. From ours only comes to mind: Mir-1 and Maksutov's mirror-lens lenses. So, unfortunately, there is very little “our” here

  • Lynx

    No, painting the jar is not good. Only filming in the pringles, only hardcore !!

  • Simon

    Into the piggy bank: I can say a couple of sentences from my experience. All sorts of Helios, Jupiters, Industars and other trash - with projection lenses, they just relax and smoke nervously. If anyone wants to understand what a real portrait painter is for little money, then this is the only place for you. And there is no need to fence the building out of cans. Buy Helicoid, insert glass and enjoy the L-class lens :))))

    • Arkady Shapoval

      Yes, and on the S5 pro

    • Dmitriy

      Could you tell me more about the helicoid? Where does such a handsome come from?

      • Simon

        From Voronezh, he offers for 3500, lost for 3300 + forwarding ... Look at Avito.

    • zzzzzz

      they play with him. already encountered know.

  • Simon

    For your information:
    KO-120M 1,8 / 120 Becomes Canon and Sony Only
    Visionar 1,6 / 84 Becomes only on cameras like Sony Next or filed on Canon
    35KP 1,8 / 100; 1,8 / 120 Becomes Nikon as a Native
    From 35KP, look for and buy only six lens options.
    All projectors belong to the class of portrait lenses, this must be known before you become disappointed expecting something else from him.
    Good luck with your creativity ...

    • Alexander

      Can you please tell me, otherwise I am already smoking from searches .., will the lens 35 KP-1,8 / 70 or not be on the Sony a57, a700 DSLR? And on the Canon 1ds markII?
      Some are convinced that yes, others - definitely not ..., I can't find anything about the flange of this glass ..., and even if I did, I don't know much about it))
      My 2/92 from Leti 60 is now on Sonya and even a flight is infinite, as far as I can understand ... because it is focused to infinity, it turns out 1-2 turns further than a sharp frame! after sharp at infinity, I do a couple more turns on the soapy frame.
      But what about these 35 KPs?

      • Rodion

        The back section is definitely enough for a DSLR.

  • Alexey

    Or maybe it's easier to buy Kaleinar 5N ?, not much more expensive than self-publishing, and at the price of a purchased helicoid.

  • Alexey

    And projectors can be used as portrait ones, but for people with a certain type of face.

    • Simon

      What kind of nonsense are you talking about a certain type? 35KP ideal distortion is zero and no kaleinar will give the picture it gives and no glass at all ... look here ... everything is done 35kp 100mm http://rasfokus.ru/photos/photo2246222.html#c4363494

  • Simon

    Click on the image and view ... http://rasfokus.ru/photos/photo2240556.html

    • Simon

      I am the first on the Internet who can show all the beauty of this lens. When I bought it I thought so - I'll play around and oh well ... because there is no Internet that could really see what kind of glass it is. And when I planted him and the first day he brought me into euphoria !!! I did not expect such a result from this glass precisely because no one showed this lens in all its glory as it is. So look practice and look for this glass. I suspect that 1,8 / 120 is exactly the same, only it should be taken on a full frame, for a crop it will be too much. 140mm is not the same lens.

  • Vadyukhin

    Fantastic, terribly liked it! And the pictures are such that it is clear - it was not for nothing that the work worked :)

  • ...

    Have fun. We must come up with a lens to shove into a Chinese glass. When Lomovsky changed 1.8 to 100 from a projector, it’s true that he invented a helicoid from helios-44. Focused somewhere up to 10 meters ..

  • Vitaliy U

    I still don't see the point in such alteration ... There are already ready-made glasses, for the same “penny” with replaceable backs (or adapters). And according to the picture (a very subjective category, by the way) they are not very different. Jupiter37, for example. And if you have $ 100 on glass, then the choice is wide.

    • Ivan

      hmm, is Jupiter 2 in aperture?) is available and high-aperture, if you wish, you can also with a verchenka worse than helios 40 - these are only projections

    • Rodion

      I'm afraid that before Petzval, Jupiter-37 - as before Beijing, ahem, in reverse.

  • Sergei

    I want to purchase 35KP 1,8 / 100 and put it on the D90 (I want to convert the helicode myself according to the above scheme), tell me, please, who is more comfortable, are they all 6 lenses? There are like 4, if so how to distinguish them, maybe by weight?

    • Rodion

      The six-lens one weighs very heavily - this is its difference, the plus was not the 35KP 1.8 / 100 petzhals.
      So take Minsky 35 KP 100 / 1.8 and you will be happy - the machine is very good.

      • Sergei

        Thank you, let me clarify: "Plus there were no petzhals marked 35KP 1.8 / 100" This means that all 35 KP 100 / 1.8 six-lens, right I understand? I have an option to buy 35 KP 100 / 1.8, the seller says the weight is 800g, he knows nothing about the number of lenses. From the photo, you can determine the number of lenses and the origin (Minsky)?

        • Rodion

          This is it, Planar, a six-lens Minsk factory. On all Minsk 35KP 100 / 1.8 six lenses.

          • Sergei

            Rodion, thanks for the information, after your message, I boldly bought a sample.

        • Simon

          He is the happiest owner of a new gorgeous lens, it will be about 150mm on the crop, otherwise I have exactly the same one, see the pictures on the link above ...

          • Sergei

            Simon, it’s precisely under the impression of your photos that I found 35KP 100 in perfect condition in perfect condition for a couple of days, as well as a turner, now I need a d16 bar.

            • Simon

              I ordered in Voronezh for Avito, it cost me 3300 + shipping ... If there is someone to sharpen and understand, then it can be cheaper ...

              • Sergei

                3300 is very expensive, according to the plan, the amount is three times less, and there it will be visible. According to Helikoid, according to the plan, the costs are only for the bar and adapter M42.

          • Sergei

            Simon, I have a few questions for you:
            1. Is the helicoid inside thread lubricated?
            2. Is the helicoid blackened inside?
            3. Maybe you can advise what, my friend will produce from scratch.
            Thank you in advance.

            • Simon

              Not blackened NO, in the internet, this factor is greatly exaggerated. It would be nice, but in practice I do not find that this somehow spoils at least something.

              Smear? No, it is not greased, so it is made that it goes smoothly and without grease and your hands do not splash into fat ... You can, of course, grease whoever you want. Usually this is done when the turner has a curve and made a backlash (large gap) then the lubricant compensates for this factor.

              • Sergei

                It’s clear that the turner is my own person, I’ll ask that I would definitely fit.

              I forgot about the account of the council. It would be nice if the thread was screwed to the carcass and the glass would ride on the thread. In my case, the thread is twisted out of the glass.

                Sorry, I didn’t understand, I will do according to the scheme that is laid out a little higher.

              • Simon

                You asked for advice, I gave it to you, the drawing above is not my drawing. And what did you not understand actually in my advice?

              • Sergei

                Understood, the question is how to implement this? Should it be a ring that rotates in place and pushes the lens through the internal thread?

              • Sergei

                Simon, thanks for the answers and advice and for your photos, tomorrow I will ask the turner how to implement your advice.

              • Simon

                What you described is the best you can think of and the most difficult. I offered you simpler but better than mine. A glass with a mount to the M42X1 camera under the adapter and a thread on the glass on top. A second glass with an internal thread is screwed onto it and a lens is attached to the front of this glass with an internal thread. This design is not complicated and will be more convenient in operation.

        but not Minsky ?, 70 mm weighs more than 400 g .., I think there are many lenses?))

        • Rodion

          There are seven lenses in 35KP 70 / 1.8, manufactured by the Izium plant. The scheme is the same as in Pancolar 55 / 1.4, only lens groups 6 - the front gluing is glued.

  • Sergei

    I see Minsky written on the instructions, this is if the instruction is from him.

  • Sergei

    It seems to figure it out, there is a Planar system 6pcs. lenses on all 35Kp 100?

    I had to climb into the nightstand, take off. Maybe someone is interested. Then without any turning operations with the help of a helicoid from helios-44m.
    Below is a photo. I dreamed a lot before, then burned out. Quarrel for balances, did not want to play. Well, the meaning is clear. watch photos by this projector offhand.
