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.

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 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

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 :)

    Here. Found! I'll take it. Lots of good feedback and great review! Thank you, Arkady!

  • Alexey

    How to distinguish the mirror and rangefinder Industar-50-2. I bought a lens converted for Nikon. Nothing close up yet. Everything is blurry in the distance. Maybe they slipped a rangefinder? But in general the picture seems to have been smeared with oil. Maybe there really is oil in there, take it apart and wash it?

    • Alexey

      Correction: Industar-50-2, if that matters.
