Overview of Industar-50-2 3,5 / 50

Industar-50-2 and Industar-50-2 are one and the same lens with different spellings of the name. At the end of the review, in the supplement, the differences between lenses with different spellings of the name are indicated.

Industar 50-2 Lens Overview

Industar 50-2 Lens Overview

TTX Industar-50-2 (Industar-50-2)
Focal length: 50 mm
Diaphragm: F3.5-F16
Number of aperture blades: 7 pieces
Thread: M42
The weight: 70gram
Optical design: 4 lenses in 3 groups (4-lens enlightened anastigmatis). The circuit is similar to Tessar lenses.
Filter Diameter: 35mm (there are also 33.5mm lenses)

Of course, after you see the lens in reality, it turns out that it is much smaller than it seems in the pictures. Industar-50-2 - very light and compact lens, I can’t even believe that in those far times they could make such small lenses. I even got the impression that Industar-50-2 pulled out of the camera of some sophisticated modern mobile smartphone.

But its size doesn’t stop the Industar-50-2 from taking great pictures. Industar-50-2 is a medium aperture... Its maximum F-number is only F / 3.5. For comparison, an aperture of F / 3.5 is 3 times 'darker' beyond F / 2.0, which is available with a number of lenses, such as MS Helios-44m-7 2 / 58

General useful information about Industar-50-2:

  1. The lens is small. Industar-50-2 can always be taken with you. It fits comfortably in your pocket.
  2. Little weight. On a hike he will not create excess weight. And with such a tiny lens, any heavy SLR camera becomes an order of magnitude lighter than other lenses.
  3. Cheap. It is unlikely that one can now find a cheaper Soviet-era lens. You can not be afraid to damage it, lose it, get it dirty - which means you can always take it with you to the most extreme conditions. Buy Industar-50-2 can be approximately 10 cu
  4. Excellent sharpness. Sharpness allows you to use the lens starting at F3.5 aperture. The sharpness of the lens is due to its optical design. The circuit was copied from brand lenses Carl Zeiss Tessar... The Tessars are also referred to as the 'Eagle Eye' for their excellent resolution performance. By the way, you can read a review of such a Tessara - Carl Zeiss Jena DDR Tessar 2.8 / 50
  5. The lens has all the necessary indicators: distance, aperture, depth of field. Moreover, the aperture indicators are duplicated twice, which is rare.
  6. Due to the small size of the lens, it is quite difficult for him to find the front cover. If not, you can use the hollow (usually white) cover from the back lens of the lenses of modern Nikon, Canon lenses, etc.
Dual aperture

Dual aperture scale. The lens has two rows of numbers for iris control.

Image quality:

The lens is almost completely fixed HA. Distortion is very small, not very different from other fifty dollars. Of course, aperture fails a little, but the Tessar scheme does not allow particularly fast lenses. A characteristic feature of Industar-50-2 is its ability to twist bokeh, this can be seen in the examples of photographs. What does it twist at the level of Helios-81n. The contrast of the lens is satisfactory. Backlight holds normally. In general, the picture on Industar-50-2 is pleasantly different for the better from the whale lenses that come with the new digital cameras.

Focus ring Industar-50-2 rotates approximately 320 degrees, which makes manual focusing very smooth and enjoyable. When focusing, the trunk of the lens lengthens by about one centimeter, while focusing front lens rotates. The depth of field scale is indicated for aperture values ​​of F / 3.5, 4, 5.6, 8, 11, 16. Compared to other fifty dollars, Industar-50-2 a rather large depth of field at F / 3.5 (seen in the picture above).

But the lens aperture control ring is quite inconvenient. It is located in front of the lens. To see what aperture value is set, you need flip the lens front lens to yourself. Iris control is smooth, without fixed values ​​- you can set any intermediate value of the F number from 3.5 to 16.0. When focusing, the aperture control ring is very, very rarely touched. The lens aperture blades have 7 pieces, they create the usual 'nuts' in the out-of-focus area in bright light sources.

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 aliexpress.com... 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.

Industar-50-2 3,5 / 50


I recently purchased INDUSTRAR-50-2 3,5 / 50 (the name is written in Cyrillic, serial number # 7457498), which differs very little from Industar-50-2 3,5 / 50 (from this review, serial number # 80126529). The differences are miniature:

  • INDUSTR-50-2 3,5 / 50 has vertical green lines to indicate the focusing distance. During focusing, the frame rim extends forward, vertical lines allow you to accurately determine the focusing distance.
  • INDUSTRAR-50-2 3,5 / 50 has an older KMZ factory logo with an arrow at the end of a stylized beam.
  • different spelling of the name: INDUSTR-50-2 and INDUSTAR-50-2

The differences are clearly shown below:

Personal experience

Modern cameras look very funny with such a small lens, some people even ask what kind of bayonet cap I have. Many photographers do not attach any importance to the capabilities of the Industar-50-2 lens, but with its help you can really get great photos. If you are interested in this lens and you want to purchase it, then contact us using the contacts from the manual optics section.

Examples of photographs on INDUSTRAR-50-2 3,5 / 50 (like this) and a camera Nikon D700 a photographer shared with readers of Radozhiva Vladimir Tuzlay:


Industar-50-2 3,5 / 50 is very compact and contented cutting half a ruble, which allows you to use it for a number of standard photo tasks. From the big conclusions, this small lens can simply be arrogant :)

Comments: 471, on the topic: Industar-50-2 3,5 / 50 overview

  • Eugene

    The lens, I'm not afraid of the word, is sincere ..) There is no point in comparing the I-50 with modern lenses, as some did in the comments. It's like (sorry for the banality) to compare the 21st Volga with the Hyundai Solaris. But the fact that you want to shoot on this glass is yes.

    • Matthew

      Especially considering its current price of 6 - 7 dollars)))

    • Alexey

      Everything about him is good. I really like him.

  • Michael

    Strange, but today I bought the same one only with the designation Industar-50.
    But he looks like this one, not a rangefinder. And the aperture is 7 blades.
    It turns out there were Industars like this before modification 2
    year of manufacture 71 (number 7111617)

    • ba3lur

      yes the first were white rangefinder and mirror just 50

  • Thomas Irkutsk

    I look at the photos and think, why didn’t they wipe the fat from the glass? :)

  • Oleg

    And in the corners on the open hole there is soap soap ... It's a pity. And there is no point in covering it up - it's already dark, where else ....

  • Bald

    I found the Industar-50-2 lens, which came with Zenit-E. In the late 60s, my parents bought it in order to record my childhood on it. But a year later they decided to buy Helios-44-2 all the same. The Industar-50-2 has not been filmed for more than half a century, and now its time has come. We'll see..

  • Bald

    Today I attached it to a Nikon1 mirrorless camera (Nikon One), through an adapter with a crop of 2.7 and in 35mm equivalent it turned out to be 135mm.

  • Bald

    I even found documents for him.

    • Victor

      Great, yes. It remains to upload a photo of what such a bundle gives.

      • Vyacheslav

        I had a Nikon 1 and an industrial 61l / d 2,8 / 53 I put it on through an adapter, took a picture of everything I could (the photo is gone). It gave nothing special at all. At the same time, there were Nikon's native autofocus lenses 11-27.5 18.5 30-110, which gave a better picture. Industar is manual rubbish for a penny and nothing else.

        • Victor

          I just have a nikolka from 30-110, I also have an industrial)) The desire to cling to it on nikolka somehow did not even arise.

          • Vyacheslav

            When I had Nikon and Industar, I didn’t think much about photography at all (although of course I didn’t think so :). In the internet there were articles about manuals on the bzk, incl. Nikon was tempting, I bought a cheap adapter for Ali and just tried to understand the magic that everyone wrote about. I did not understand :), which is not surprising, what was there to catch with this crop.
            Now there is already a new bzk nikon z50, the crop is already 1,5 instead of 2,7 and I understand about what I could get from the industrial, but I no longer need it. Instead of aperture 2,8, autofocus fixes 35 50 Nikon have already been bought, and there is no point in fiddling with Soviet manuals. If you really buy a manual, then 1,2 and immediately under the Nikon Z mount. The rest is a waste of money.

  • Matthew

    Thank you for letting me know how to use it with a full-frame Canon, otherwise I completely forgot about it. It will be necessary to fasten and click)))

  • Paul

    Do you need an M-42 with a lens to focus INDUSTAR-50-2 to infinity, or will focus without a lens be possible?

    • Oleg

      on which camera? Yes for kenon, no for nikon

      • Oleg

        In the sense of kenon everything becomes without a lens, but nikon does not

        • Victor

          On a mirror kenon, far from everything becomes without a lens (although certainly more than on a mirror nikon)

          • Oleg

            Industar 50-2 becomes without a lens

  • Paul

    Thanks for the answers, camera Nikon and have already figured out the question. In the internet and on YouTube there is infa about how to modify Industar 50-2 for Nikon. Some of the lenses can be refined by twisting a couple of screws, while the other part will have to be protookar on the machine. Optically, they all give out different sharpness, so how lucky.
