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
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.
Industar-50-2 on a modern digital camera
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
Lens view Industar 50-2
General useful information about Industar-50-2:
- The lens is small. Industar-50-2 can always be taken with you. It fits comfortably in your pocket.
- 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.
- 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
- 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
- The lens has all the necessary indicators: distance, aperture, depth of field. Moreover, the aperture indicators are duplicated twice, which is rare.
- 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 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.
View of the Industar-50-2 lens when focusing on MDF
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).
Industar-50-2 with native ZENIT front cover
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 at 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, with the Nikon F-mount), you need to use adapters with a corrective lens, which allows you to focus correctly at all focusing distances. For any mirrorless cameras, 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
Addition
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.

selling industar 50-2.
Also tested this lens. Shot macro. It turns out very well. All scratches are visible even on small details.
The I-50 is greatly underestimated - in fact, it is quite a usable lens. They can even click portraits completely. It should be more fun on the full frame than on the crop, because twists the bokeshka.
A comrade sells it to me with macro rings for 500 rubles. I will take it!
And this is the original size of the object, shot by Helios
Thanks for the interesting review.
I am a beginner - and it is important for me to learn how to do everything manually. Therefore, some time ago I became interested in Soviet optics: cheap and everything is manual, twist it as much as you like. After your review, I bought an Industar 50-2. After use, there were questions.
Portraits and small objects are fine, but landscapes are not so smooth. When focusing at infinity, even with closed apertures, I cannot achieve satisfactory sharpness. You look - everything seems to be fine, you enlarge the image a little - soap. Or am I expecting too much from the fifty dollar, using it on the landscape?
Camera: Canon 600d + adapter with dandelion.
Maybe he still does not reach infinity (a feature of a particular instance)? On Canon it should, then somewhere is a jamb.
... we try the second Industar 50-2 and compare
marriage on the lens, most likely.
maybe someone was trying to remake it under nikon.
I also have this situation, on canon does not reach infinity. I will try to remove one adjustment ring. Here it is not difficult, judging by the descriptions.
Arkady, do I understand correctly that the lens with the name in the Latin alphabet is an export version and the quality of these will generally be better?
Such legends go. Nowadays, you need to look at a specific instance.
I have an industrial 50-2 under m39
I thought they were only with M42 thread.
The story of the sudden inequality of instances of Industar 50-2 and Industar 50-2
I used my Industar 50-2 since the bearded 98th with varying success (sometime with films ...). I felt all the strength when I screwed the contrast to Sony alpha 3500, the clarity is at the level of quite solid lenses !!! Nice color, nice bokeh, everything is smooth. Of course, the fear of backlight is yes ...
Got to experiment with Industar 50-2. I thought before disassembling to check - and SUDDENLY! If Industar puts out a rainbow from a light bulb in a room, then Industar gives in the same places a rainbow 3 times fainter in brightness, in places not noticeable at all.
Perplexed by a few ...
So, it means that this industrial was lying with me and I remembered it so disgustedly when I came across it :)))) And today I decided to wear it on Canon 5D ... Then see for yourself what happened ...

Fig. 3
And now I look at the pictures above with some sprat and I don’t understand, or do people not know how to sow, or do they have plastic lenses there?
And it seems to me that export and import have nothing to do with it. It's the old fashioned way that they underestimated their country and sold it for demon crt :)))
I completely forgot to say RAW showed up in this test, but I can tell you that JPG was not bad. I just wanted to understand what you can get from this lens in RAW. As I opened the footage on my computer, I got crazy ... and I called my wife and my son to look at this miracle ... So, now this is a free piece of glass my friend for always! :)))))
Well, in the review, he is 36 megapixels Sony a7p showed no worse than himself.
Arkady I was embarrassed by what they began to show in the comments ... And I just fell in love with this glass ... My wife got the same cool result. On the street I will try later, but in the morning I took a few shots through the window and realized that on the street he would show himself a fine fellow, I will show later what happened ...
I thank Arkady for the wonderful site ... I often run here to look at help ...
For photographing a wife, the lens is very sharp :)
It depends on who has a wife ... :))))))
Hello! Remaking for infinity Industar for Nikon is very simple. At the back of the pictures of the lens itself in the review you can see the adjustment nut. She, as a rule (maybe there are other options, but I have not seen one yet), holds the entire rear lens unit. Unscrew it so that infinity with an adapter without a lens (thin, otherwise it may not be enough just block length) was (determined empirically: after each movement with a screwdriver, hook the lens onto the camera, aim at the remote landscape from the window and take it off, and then examine the r-tat comparing it with the previous pictures) and gently glue the nut (to fix it in the right position) with a black cloth insulating tape. Spins, as before, sharp as before.
By the way, Helios 44-2 is being redesigned in a similar way. Only there, the back ring only presses one lens, which lies freely inside the frame. I put a ring made of an old guitar string under this lens (blackened :-)), the 4th string from a set of “ten” came up to me. Then I put it all together again, I didn’t seem to lose either bokeh or sharpness. So, if anyone needs it ...
Oh, sorry, I forgot the second point. All my Soviet optics (Helios-44-2, Industary - 50-2 and 22U) fit perfectly (without flares) into the Nikon mount just like that, without any adapter. True, there are some difficulties with hand holding. Also, if someone needs it suddenly.
Hello! Tell me how industrial will work with canon 600 ??
As well as with others. The question is not very clear. Will photograph, on a covered diaphragm even sharply.
Please tell me, does this lens have the same optical design as the i96u 3.5 / 50 from the enlarger?
(The thought crept into my head to try to swap the lenses ...)
Although they are identical in characteristics, the I-96U seems to be designed to work at a finite distance. In short, this is still a different lens, hardly lenses are interchangeable.
Plus, in photomagnification lenses, the lenses are rolled into pancakes, in photographic ones - not.
Yeah ... They have a different working distance, industrial 50 2 - M42, and u96u M39 - it's immediately clear that it won't work ...

Good day! I ordered it yesterday, and today I arrived, opened the parcel and gasped! as soon as from the factory (did not expect) for just 6 ye with an adapter m42 / eos with a chip) brought it in 40d, slapped the cat in a hurry and went crazy (not special, but just like sharpness) .. put it in K20 ... glass number 8305662 Krasnogorsk) so the question is, why the hell are I expensive canon and pentax? for an amateur above the roof, if I take something with me, and suddenly there you can also take a picture :-))) ... Arkady! thank you for the great reviews
Photo of a cat! ^ __ ^
A very interesting review. I use the Industar-50-2 on a Sony-slt57 camera through an m42-mA AF-1 adapter. 1987 Lens release, Krasnogorsk plant. I bought it in 1988 and will survive more than one camera. Photos are excellent.
PS I often read your reviews and articles. Thank you for being …
Mistake! When focusing in Industar-50, it is not the front lens that rotates (this is not a triplet, as in Smena and Lyubitel), but the entire lens unit moves relative to the film plane.
Mistake! When focusing Industar-50, it is not the front lens that rotates (this is not a triplet, as in Smena and Lyubitel, which changes the focal length of the lens and this achieves focusing on focus), but the entire lens moves relative to the film plane. block. “I-50-2” was recalculated in comparison with the early “I-50” to increase the resolution. On the rangefinder FED, Zorkiy, Mir, Leningrad, Friend and Zenit, according to the first series of Zenit-E, the connecting thread was M39x1 with a working distance of 45,3 mm, then they switched to M42x1 with increasing the working distance up to 45,5 mm. Therefore, lenses of M39 DSLRs are installed on M42 cameras through an adapter, on the contrary, it will not work, or you need to change the camera's threaded seat ring. Lenses M39 rangefinder cameras with a working distance of 28,8 mm, installed on Zenits with an M39 thread and a working distance of 45,3 mm, are obtained as if with an extension ring of 16,5 mm (for reproduction, macro photography. Or it is necessary to shorten the frame accordingly. However lenses with M42 are not in short supply, especially the I-50-2.
Suddenly! The whole lens block, the whole Carl! The shift is also full. But Arkady writes not about the front lens and the focusing system, but about the possibility of using polar explorers with convenience.
Friends, please tell me: I have an Industar 50-2, the external state of which is not satisfactory. But my copy at open F3.5 is decently “darker” than at the same F3.5 Nikkor 50mm 1.8G. I also compared it with Helios 81n (both on F4) - the result is the same, on equal settings the images from Industar 50-2 are not noticeably over-exposed. How are things going with your copies - do they really transmit less light (for example, due to their simple enlightenment) than lenses of a higher class at comparable aperture values, all other things being equal, or do I have such a copy?
Good afternoon! It's all about the diameter of the front lens - the larger it is, the more light the lens lets through, and aperture is just a term referring to the lens design. Those. two lenses with the same aperture but different lens diameters have different apertures, so the industar is darker - its front lens is much smaller than the other lenses you named.
The comment above contains lulz ...
This is something like this:
1. Indeed, as you indicated, due to differences in the type of enlightenment, a simple lens such as the I50 with small thicknesses of lenses can transmit less light than a planar-shaped 50 / 1.8.
2. Industar-50 has 50% geometric vignetting at an open aperture, which, as you know, means a drop in illumination to the edge from the specified. In other words, it turns out that the luminosity indicated on the lens is not an “integral” value, which does not take into account the possible difference between the illumination of the center and the edge.
Nikkor 50 / 1.8 on a covered diaphragm will not have geometric vignetting, because the light distribution will be uniform, without falling to the edge.
Both factors can lead to the observed result. Successes.
Apples and uncle in Kiev.
The man wrote about Thomas, and you about Yerema.
Very strange answer.
Rodion is right and gave a substantive answer, unlike Denis, who provided incorrect information.
In my opinion, when Denis wrote that “in the diameter of the front lens - the larger it is, the more light the lens lets through” and “two lenses with the same aperture but different lens diameters have different apertures” from a part he was somewhat right.
For example, Tokina 24-70 / 2.8 is more “aperture” than Nikkor 24-70 / 2.8, which is expressed in faster shutter speeds with completely identical preset aperture and ISO settings, as well as focal. The exposure is also adjusted. The diameter of the light-collecting lens is 82mm for Tokina and 77mm for Nikkor. I understand that optically, they can be noticeably different and I do not argue. But the fact that the larger diameter of the light-collecting lens has a positive effect on the “luminosity” of the lens still takes place, although this is not always noticeable.
In the general case, there is no direct dependence on the front lens diameter and aperture ratio. A good counter example is lenses for mobile phones with f / 1.7-f / 2 with an EGF of 24-28mm.
Simple counter-examples are Nikon 50 / 1.4D and Sigma 50 / 1.4 HSM. The diameter of the front lens is unknown, but the diameter of the filters is known: 52 and 77 mm. The diameters differ by 1.5 times, while the exposure is practically the same.
Once again - there is no direct relationship, it cannot be said that the larger the front lens, the faster the lens. Everything depends much more on the optical scheme, focal length and frame format for which the lens is designed.
But do not confuse the aperture (f-feet), which is a strictly geometric parameter, with the effective aperture (T-feet), which takes into account the light transmission and other amenities of life.
About the diameter of the front lens of retrofocus lenses (most of the current especially high-aperture glasses, universal zooms and shirikov) to speak generally bad manners, because it is scattering and does not collect light in any way). The “rule” of the size of the front lens works more or less only with simple telephoto lenses (for example, Jupiters, Tair), as well as with lenses that are compact relative to the optical center (triplet, tessar - and that is the nuances of darkness).
The effect you observed with two zooms can either indicate that the electronics are incorrectly exhibiting, or about different light transmission of the lenses.
The simplest example of the second case. We take two glasses - Helios-81H 50/2 and Takumar 50 / 1.4 and suddenly we find that exposure with takumar on the open one is 1/3 of a stop longer than that of Helios on the open one. SHOCK !!! 11 And all because thorium during alpha decay kills the microstructure of glass and it turns yellow, acquiring a wild extinction coefficient. And so - takumar is twice as light geometrically)
But what do you think f-stops and T-stops have no connection?
There is no geometry there and there the Kenonowsky light transmission is 50 / 1.2, for example, in f-stops it is darker than its declared aperture
I apologize for the t-stops of course
By the way, is thorium yellowness treated with ultraviolet light? I'm talking about Takumar. And in G81N lanthanum glasses with magic bubbles :) which undoubtedly has a beneficial effect on the luminosity (all the power is in the bubbles!)
You are well done Rodion, I always admire your enthusiasm and your skillful hands.
And why did you draw such a conclusion? Despite the clearly rhetorical and provocative question, I will give in and write in detail.
They have a connection, obviously, through the coefficient of proportionality. "Which takes into account light transmission and other delights of life." But as soon as you start talking about the size of lenses, this clearly indicates the transition to the consideration of geometric parameters, i.e. f-, not T-stops. And in these specific examples (I-50 and nikkor, zooms) this is a wrong step. Good? Anything else you want to know about what I believe?)
Yes, the question is provocative. He asked him because to the interesting question of Mikhail Menshov, Denis answered in the right direction, albeit partially. And you concentrated only on the light transmission coefficient, without indicating the importance of the proportionality coefficient, which clearly shows that the aperture ratio depends on the ratio of the entrance pupil diameter to the rear focal length. And f-stops, these geometric parameters determine T-stops taking into account the light transmission coefficient, which, of course, only spoils everything. So, size matters, and not only in a well-known joke :).
And the correct answer was given by Anonymous in the post above, yes, the industrial aperture does not have an effective aperture of open 3,5, it is embossed on it with a geometric aperture, the effective one is significantly less. But those brought by Mikhail Nikor 50 1,8 and Helios 50 2,0 on aperture 4 have the corresponding 4 precisely the effective aperture.
But why would they have an effective aperture of 4 equal to 5? Why on earth suddenly? What are you talking about, comrade?
And where did you see 5 in my post?
Typo. 4. But the essence is the same.
And what is the same essence of your question? I did not see the essence in your question. What is wrong with what I wrote?
Okay, I understand, clearly)))))))))))))))))))))
I came across a third type lens. The name is in Latin letters, but there are vertical green stripes and the logo is old. Year of manufacture 1975)
Stripes are not uncommon, but the norm for this lens. Rarity is the absence of "stripes"
