Mir-1V 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... Mir-1 exists in modifications with threads m39, m42, for Kiev SLR cameras, with a replaceable shank (Mir-1A), and even “simplified” variations of the “School” type. Refers to wide angle lenses. Major modifications:
- Mir-1 with M39 × 1 mount.
- Mir-1 Avtomat with bayonet mount for Kiev-10 and Kiev-15 SLR cameras.
- "Mir-1Ts" with a "C" mount for DSLR cameras of the "Zenit-4" family with a central lens shutter.
- Mir-1A - with replaceable adapter shank. After installing the appropriate adapter, it could be used on cameras with different mounts, including M42 × 1.
- "Mir-1V" ("Vologda") early, before 1990 - the most common lens from the entire Mir series, produced at VOMZ. Fastening - thread M42 × 1. The early ones - with a logo in the form of an arrow passing through the letter "B", the later ones - with a modern stylization of the logo.
- "Mir-1V" ("Vologda") late, after 1990 - in the 1990s Mir-1V has already been produced with a modernized frame, but the device and optical characteristics have not changed. Fastening - thread M42 × 1.
- "Mir-1Sh" ("School") - rejected by the quality control department of the party "Mir-1V", intended for the centralized supply of school photo circles. But it is not exactly. Thread M42 × 1.
The Mir-1 was the first Soviet retro-focus wide-angle lens, made on the principle of an "inverted telephoto lens" and suitable for use with single-lens reflex cameras. It was intended primarily as a replacement for the latest Zenit cameras at that time and for several years remained the widest-angle lens for SLR cameras in the USSR. Variants for television cameras and other equipment were also produced.

Lens in work
Mir-1V, as a lens, is not very happy with ringing sharpness, resistance to backlight and image micro-contrast. A focal length of 37 mm on full-frame cameras makes Mir-1V as useful in everyday life as Canon EF 40mm f2.8 canon pancake ... If not for one thing. Not a "wide-angle" focusing ring, but a portrait one. Scale too fine for wide angle. At least at close range, there are definitely problems with getting into sharpness.
On cropped cameras, of course, the situation is a little better - the viewing angle of the Mir-1V can be roughly placed in a row with "fifty dollars", but the depth of field, although it increases, is not much. Mir-1V has one interesting property - the swirling of the background and sharply outlined circles of glare in the out-of-focus area. A similar effect has Helios, Pentacons 50mm, 29mm, and some other lens models.
The design is interesting. Honestly. I liked the look of this lens. The focusing ring is tight if the lubricant is dry (classic of manual optics of the USSR), rotates 360 degrees, but is close to the end lens, and, accordingly, to the camera. There is a preset aperture ring. The diaphragm ring is too easy to move, and the set value constantly gets lost, even from a light touch. It is inconvenient to use with gloves - all the time the focus ring and the diaphragm strive to rotate together. In the later version of the Mir-1V frame, it is quite a disaster. The rings are on the same level, and without looking at the lens, you can turn even three rings (including the focusing ring).
Despite the fact that the lens is a wide-angle lens, it cannot be called a classic wide-angle with a large depth of field. I would call it a wide-angle portrait lens, as the depth of field at short distances allows you to fine-tune the sharpness. By the way, this is evidenced by the marking of the focusing range - at distances up to 10 meters, the step of the marks on the body is quite large.
In order to shoot from the waist, you need to clamp the aperture down to f / 16, and then you need to control the sharpness range. The lens has a flight over infinity.
The blades of the Mir-1V diaphragm shine and shimmer. The petals, although matte, are gray, not black. This did not have a positive effect on the quality of the picture. There are eight blades in the diaphragm in total.
The rear of the lens, unlike some portraits (for rangefinders, for example), is darkened. This should not create multiple reflections when bright light sources hit the frame. When open, it greatly blurs the background, swirls it, but lathers... The lens in the updated frame also gives moire, it is not very comfortable to work with it at an open aperture. Perhaps he just needed an adjustment, or maybe just a lens from some installation batch, judging by the number on the body. It is impossible to focus correctly without enlarging the picture in the viewfinder. Dislikes shooting against a bright background.
Focus and iris operation
Focusing (focusing) is performed by rotating the ring with the marked distance scale. The distance scale index is the central red line of the depth-of-field scale. The design of the diaphragm presetting unit allows you to change the position of the diaphragm limiter, which is done by turning the ring on which the diaphragm scale is applied. The index of the pre-set stop is a point marked on the fixed part of the frame.
The actual diaphragm is performed by rotating the diaphragm ring. The lens is screwed into the camera until it stops and tightened slightly. Before starting work diaphragm set to the maximum hole by rotating the ring until it stops by aligning two points. Turning the ring, set the stop in accordance with the selected working diaphragm by aligning the index with the required number on the diaphragm scale.
At the same time, you should feel a slight click, confirming that the preset ring is locked. Focusing by turning the ring for curly knurling at the maximum aperture lens, without interrupting the observation of the subject, turn the aperture ring until it stops, and then press the camera shutter button. If the distance to the subject is known in advance, find it on the distance scale and turn the ring to set this value against the red index. The distance to the subject is measured along the optical axis lens from the plane of the sensor or film, usually indicated on the camera.
When photographing objects at different distances from the camera, it is recommended to use the depth-of-field scale. It consists of pairs of divisions, symmetrically located on both sides of the index. Each pair corresponds to a certain value of the set aperture. Against these divisions, you can read two values on the distance scale, within which all objects will appear sharply in the picture. These two distances are referred to as the near and far limits of the depth of field.
Color aberrations at apertures up to f / 4, the difficulty in controlling sharpness during focusing through the viewfinder, as well as the tight movement of the focusing ring close by and the virtual lack of sharpness ... leaves not the best opinion. HA:
Distortion is not very noticeable. but it is. An interesting effect of the drop in sharpness at the edge of the image:
But in this photo you can see how Mir-1V behaves on the open one when shooting against the background of the sky.
Effect is enhanced:
Vignetting disappears (more precisely, leveled out) at f / 5.6. Center sharpness and hips at f / 6.3 it looks like this:
Picture "lack of sharpness at f / 3.2". The cropping of the first image makes it clear about the quality of the image around the edges.
It can be used in artistic photography, but personally, the lens has caused conflicting feelings in me. Despite its low sharpness, the picture is harmonious (color rendering is not lame).
For problem-free operation on Canon 1Ds, lens I had to cut off the part that rises above the last optical element, otherwise the camera mirror would cling to the lens (on Zeniths and cropped Canon cameras, the mirror area is much smaller, and tail cutting is not required. On mirrorless cameras, this operation is not necessary, and this applies to all generations lenses Mir-1V. On a later modification, the metal plate is reduced).
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 60mm focal length, and the aperture will correspond to the value f / 4,5... Why is that? Because, firstly, because of the narrow viewing angle, you will have to move further. Secondly, the camera's sensor receives 1,6 times less light than a full-frame 35mm sensor. Thirdly, although this does not apply to the previous two statements, the lens on the crop has a drop in sharpness due to the denser arrangement of pixels on the matrix and their concentration in the center of the lens.
In practice, the lens is best used on a full frame. Despite the fact that the cropped sensor will work with the sharpest part of the lens (in the center), these lenses give the best image quality exactly on the full frame, since in the center the optics, although sharper, still have the pixel density on the cropped matrix many times higher. From this it turns out that we, as if under a magnifying glass, are examining the optical distortion of the lens.
It is advisable to use a hood with the Mir-1V lens, otherwise the image quality drops. When buying, you should carefully check the copies for software with an open aperture.
The easiest way to shoot is 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.

When ordering, it should be borne in mind that cheap adapters of poor quality with a lens for Nikon F significantly spoil the picture. Adapters without a lens reduce the maximum focusing range (due to the difference in focal lengths). Adapters with chips come across poor quality, exposure metering and focus confirmation on some Canon EOS models may suffer from this.

A lens that is easy to buy and hard to sell. Mir-1V, even in perfect condition, due to the abundance of conflicting reviews, not everyone wants to buy. It is especially repulsive that the optical qualities lens far from up to par, and sharpness, in comparison with its early copies of the release of KMZ, Zagorsk and even the Valdai "Jupiter", is not very impressive. The model, which received the Grand Prix at the Brussels Exhibition in 1958 and a second degree diploma from the VDNKh of the USSR, has remained in the distant past and seems to have nothing to do with later releases. The lens performed best on full-frame cameras. For cropped cameras, it’s better to look at something else.
