Mir-1V is a lens for small-format cameras with M42x1 / 45,5 thread. Mir-1V - This is a Mir-1 lens produced at Vologda Optical Plant. "B" means "Vologda". Miracle, "work of art" VOMZ (Vologda Optical and Mechanical Plant). The model is as long-lasting as Helios, the production history is not limited to one modification. The review uses materials from the lenses serial numbers:

number85015166 (Sample photo on Sony A7) release '85, in excellent technical condition.

number89018719 (sample photo on Canon 600D and 60D), 89 edition, tight focusing ring, bubble in the front lens.

and No.00000971 (example photo on Canon 7D) - released after 1990, modernized frame

 

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.

Everything written below refers to Mir-1V and Mir-1V lenses in a modernized frame, unless specifically noted otherwise.

Mir-1V scheme

Mir-1V is built on the optical scheme of Flektogon lenses from Carl Zeiss recalculated for Soviet glass.

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.

Body, ergonomics

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.
