Industar 50-2 is a lens from the era of industrialization of the USSR. The most compact of all Soviet lenses for SLR cameras that were produced in the Soviet Union. Despite the miniature size and years of production, Industar 50-2 is able to give a high-quality picture on modern digital cameras.

Miniature Soviet lens, made according to the "Tessar" scheme. Industar 50-2 is a lens for SLR cameras with M42 screw connection. This lens is installed on modern SLR and mirrorless cameras through the appropriate adapter. Read the article about adapters... Industar-50-2 - the cheapest Soviet manual lens and is "Kitovym (kit)".

Industar 50-2 - standard lens for Zorky cameras, "ZENITH", which replaced Industar-50. Tessar-type coated four-lens anastigmat in a threaded frame with a non-retractable tube. Equipped with an iris diaphragm. For its time, it had high resolution with well-corrected chromatic aberration. Recommended for all types of shooting, including shooting on color film and for reproductions. On later versions of lenses made in the USSR, the year of manufacture of the lens can be found on the basis of the first two digits of the serial number stamped on the bottom of the focus ring frame.

Lenses similar to Industar 50-2 3.5 / 50

Industar-50-2 is a continuation of the Industar-50 line. Industar-50, in turn, is a recalculated Industar-22.

The variations of Industar 50-2 themselves are much smaller than Industar-50:

  • Industar-50-2 black for SLR cameras with white font
  • Industar-50-2 black for SLR cameras with white-green font (example photo below)
  • Industar-50-2 black for SLR cameras with white lettering
  • Industar-50-2 black for SLR cameras with white-green font

Industar-50 is known in variants for photographic enlargers. Lenses with multi-coating (MC) were not produced.

 

Focusing

The focus ring of the Industar-50-2 is located just behind the aperture ring. With this design, it is difficult to control the lens, and if the grease near the focus ring is dry, the aperture ring leads the focus ring. The minimum focusing distance is 65 centimeters, the focus ring rotates almost 360 degrees around the axis, and thanks to this it allows you to more accurately adjust the focus. Very sharp from f5.6, and wide open it allows you to take portraits with background swirling.

Diaphragm

The lens aperture is controlled by a ring located on the front of the body. The diaphragm consists of 7 blades, and at narrow values, in the out-of-focus area, "nuts" will be noticeable. Maximum diaphragm Industar-50-2 - f/3.5. In the presence of bright sources in the frame, the lens, in addition to losing contrast, also draws reflections on the matrix, even in the light of a flashlight. Reflections rotate around their axis when the focus ring is rotated.

Depth of field control

Despite the large depth of field, focusing on cameras with a small viewfinder can lead to problems with hitting the target. You have to use LiveView mode much more often than with autofocus lenses. As an alternative to LiveView, you can use the distance scale and the depth of field of the lens itself, or adapter rings with a focus confirmation chip (more expensive, but not much more effective).

Industar 50-2 can be set to hyperfocal distance using the depth of field calculator printed on the body, and shoot without touching the viewfinder eyepiece. This is useful in street photography, for example.

Aberration

The Industar 50-2 corrects or minimizes aberrations such as astigmatism, spherical and spherochromatic aberrations. The tessar scheme itself implies high sharpness and minimization of various aberrations. On the open aperture of Industar-50-2, I noticed a slight green coating on the borders with contrasting transitions. So light that it can be neglected.

Vignetting

At the widest aperture, the Industar 50-2 has strong vignetting in the corners of the frame. Disappears already by f / 4. On a cropped camera, it will not be noticeable at all.

Sharpness, contrast, color

At the open Industar 50-2 there is a drop in sharpness towards the edge of the image, which is eliminated by deviating the aperture ring half a stop in the direction of narrowing the aperture. Industar 50-2 does not like bright backgrounds, local light sources in the frame. However, it tolerates their presence better than the first "fifties". Open/5.6:

Case and build quality

The gripe is the location of the aperture ring. In view of the small dimensions, the location of the diaphragm ring causes great inconvenience in operation. Such an arrangement of small rings one after the other, as on the Industar 50-2, forces you to be distracted to set aperture values. All the lenses that came across suffered in one way or another from the problems associated with the miniaturization of the controls. To work with unmaintained lenses, both hands must be used.

industar 50 2 canon liveviewer.ru 13

With one hand you have to hold the focusing ring, with the other you have to set the aperture. 70% area lens occupies the focus ring. 15% - on the base and diaphragm ring. It is worth being patient and adapting in order to achieve more or less precise lens control “on the fly”. Build quality has complaints. The gaps of the rings are felt, because of them something interesting happens:

  • The aperture ring (ALWAYS!) Pulls out the focusing ring.
  • The focusing ring when rotating on a serviceable one, Industar drags the aperture ring when rotating.

To be honest, although Industar 50-2 is built on the same principle as the tube Industar-50 or Industar-22, it is more convenient to work with the latter. Industar 50-2 is easy to disassemble, does not require special skills other than attentiveness. When disassembling, pay attention to the blackening of the case. The slightest wrong move with a screwdriver, and the paint peels off. The inscriptions on the frame are engraved and painted over. Colors may vary. I came across both with yellow, green and white inscriptions.

Lens advantages

  • Lack of autofocus I am not worried - in portrait photography and macro, it can be omitted.
  • DOF calculator and distance scale in most modern lenses is not represented by anything. Industar 50-2 can be set according to the lens marks and shoot without looking through the viewfinder eyepiece.
  • Sturdy construction. The lens is not afraid of changes in temperature, altitude and humidity, drops. The metal body will not crack on impact, the lack of electronics and tolerances for rough assembly allows you to handle the lens without sparing it.
  • Can be used with any digital cameras, through an adapter from M42x1.
  • Miniature size allows you to easily carry it with you on long hikes, and simply, "on the light". A miniature lens hood can be found under the lens. Industar-22, and shoot in bright light.
  • High maintainability... The lens can be repaired on the knee.

The main trump card of the lens is its small dimensions and scanty weight. The Industar 50-2 lens weighs only 112 grams.

Use on modern cameras

On a camera with APS-C sensor (kf = 1.6) the camera will have a field of view equal to the equivalent 80mm focal length, and the aperture will correspond to the value f / 5,6. Why is that? Due to the narrow viewing angle, you will have to move further. A lens mounted on a camera with a small matrix has a drop in sharpness due to a denser arrangement of pixels on the matrix and their concentration in the center of the lens. It is easiest to shoot in the mode Aperture Priority (Av)when the camera adjusts the required shutter speed based on the current aperture value and the light in the frame. To work on digital cameras, you need an adapter from the M42x1 threaded connection to your camera. Industar 50-2 3.5 / 50 it is easiest to put on Canon EOS with EF (-s) mount, due to the insignificant difference in focal lengths. Adapters without focus confirmation chips on Canon are cheap.

Industar 50-2 (50mm f / 3.5) on a full-frame camera

Has a 45 degree field of view, standard lens. Vignetting will be observed around the edges of the frame at wide apertures.

Industar 50-2 (50mm f / 3.5) at 1,6 crop

Will have an angle of view equal to ~73mm lens for full frame. Vignetting Industar 50-2 will not be noticeable. It is permissible to use for portraits and reproductions.

Alternatives Industar 50-2 (50mm f / 3.5)

The main probable application of Industar 50-2 is for shooting bust portraits, shooting on a hike (when weight matters). The lens is not suitable for video shooting. management is far from the best. The alternatives below are a legacy of yesteryear that is still in use today.

Helios 44 series

Helios of any modification will have better artistic characteristics due to the working wide aperture of f / 2, and older Helios models are more resistant to backlight.

Sample photos

If we compare the picture with Industar-50, it turns out that Industar-50-2 wins significantly in image quality. the veil at an open aperture is almost invisible, and is eliminated by twisting the contrast when converting RAW. Sharpness is also noticeably better, and vignetting, although present, is not so striking.

Summary

Not a bad, "first easy fix" for a novice amateur photographer, if you close your eyes to the shortcomings of the controls and the darkness of the image. Its shortcomings in ergonomics do not diminish its merits in the least - the lens perfectly fulfills its direct functions. Given the low cost on Internet sites, it regularly finds its owners for a long time.

  1. I have an Industar on Canon. I am glad that there are adapters. I am pleased with the sharpness of photos both in normal shooting and in macro photography.

  2. I like that the Industar-50-2 50mm f / 3.5 has adapters for many modern camera models. I have Nikon DX / FX and Samsung NX, thanks to this lens, the photos are of excellent quality on both cameras.

  3. I want to add on my own. Standard lens for a camera produced for the 80 Olympics at the Krasnogorsk Mechanical Plant.

  4. Not the best pictures, but I came across such a life hack, people advertise that they are taking modern pictures on the lens of the times of the USSR and the most interesting thing is that it is now in demand and fans of the USSR are ordering pictures from it.

  5. I love to travel with my husband and take pictures of new landscapes of all seasons. Industar-50-2 50mm f / 3.5 pleased me with good photo quality and ease of disassembly. A big plus is that there are adapters, since we have different cameras. And we also made sure that the harsh winter and falls are not terrible for this lens. For travel and hiking just what you need.

  6. The given optical scheme is not a scheme for Industar 50.
    The diameter of the glasses cannot be 49 mm, and the lens length is 81 mm, and the flange distance is 183 mm.
    This is some kind of lens for a fur camera. but definitely not for a DSLR.

      1. The scheme is of course tessar, but it is signed as "Scheme Industar 50-2"
        Your experience with this lens described in the article is very interesting.
        And I went to your article while looking for the optical scheme Industar 50-2, and was surprised to see it.

        1. well ... analyzing the industries I see the same thing. 4 lenses, 3 groups. He is a Tessar and Tessar in Africa. Yes, it was probably worth covering up the dimensions, but I did not consider this an important critical moment. For me it’s just, it’s obvious that the industrial is 50, that the fed is 3,5 / 50, that the i-22, i-10, i-61, i-51, that the rest of the tessars are one and the same. canon 50 1.8, for example, is also a Tessar, but modified.
