The Vega-M-1 35 / 2.8 lens was designed in 1960 at the KMZ (Evseeva G.I., Maltsev M.D.) and was intended for the Narcissus narrow-film SLR camera. The camera was conceived for medical and technical use, but in the end it became an "elite Soviet crop", which did not take root in its homeland due to its rare format, but went well for export. Since just over 10 cameras were produced, Narcissus has a collectible value.

Vega-M-1 was supplied as a standard lens, but the angle of view on the 16 mm film format turned out to be 40 °, not 45 ° - apparently, as in the case of Helios-44, we had to choose the focal length so that the rear focal length a section of the lens made it possible to use it on an SLR camera Important: the Narcissa mirror and the mirror of even modern APS-C DSLRs are very different in size, therefore, even on APS-C SLR cameras Vega-M-1 does not allow focusing to infinity!

There were two production versions of the lens: a white body (rare) and a black one (the most common, presented in this article). Experimental lenses produced in 1960 were called "Vega" without additional designations. Early production samples - "Vega-1M" or "Vega M-1". Taking into account the small-scale production at KMZ of another lens Vega-1 50 / 2.8 (predecessor Vega 3), the name of the narrow-film staff caused a lot of confusion.

Features of the design and adaptation of the lens

A pleasant feature of Vega-M-1 is the FED / Zorky working distance, unified with Soviet rangefinder cameras, equal to 28.8 mm. To install the lens on a modern camera, it is enough to make an adapter ring M24 * 1-> M39 * 1. Full use is possible only on mirrorless cameras due to the short rear focal length of the lens.

An unpleasant feature is the design of the helicoid. Its stroke is quite large for a 35 mm MDF lens - as much as 0.5 m. For comparison: the MDF Mir-1A 37 / 2.8 is 0.24 m. Focusing with the lens is unpleasant because of the narrow focusing ring with corrugation cutting the fingers. The lens had the same problem. Vega 3... To eliminate these shortcomings, I used a 10-15 mm macrogelcoid with a thin M42-NEX ring as an adapter. It did not become much easier to focus, but the MDF decreased very noticeably without losing focus to infinity.

The lens diaphragm consists of 7 rounded dark but shiny blades. Perhaps, in this case, the engineers took the diaphragm assembly of the mass Industar-50-2 as a basis. The diaphragm forms an opening in the form of a distorted heptagon, but in reality, the uneven edge of the discs in the bokeh rarely manifests itself.
Vega-M-1 is much smaller in size than most lenses (even than Industar-50!). On the Sony A7s, the nose of the lens barely protrudes from the camera grip.

Optics Vega-M-1 has the usual single-layer coating of violet shades - typical for the early 60s. The lens turns slightly yellow in the light.

Summing up, it can be noted that Vega-M-1 is a small, but inconvenient lens: a clumsy focusing ring, a large MDF greatly spoil the tactile perception. But it is very compact and easily adaptable to modern mirrorless cameras.

Optical properties

Among Carl Zeiss small format lenses, there was a rather rare Biometar 35 / 2.8 T http://alii.pub/6alpff" target="_blank" title="/lenses/item/c_4149.html for Contax cameras with a frame format of 36 * 24 mm. Vega-M-1 uses the same type of optical design, which suggests the possibility of working with full-frame cameras. In reality, the Vega-M-3 does not cover the full frame of the 2:1 format, but it copes well with the full frame of the 4:3 format. There are also no problems with black corners when focusing on MDF even at a 3:2 aspect ratio. On crop cameras, of course, there will be no problems with vignette.

Vega-M-1 creates a sharp image in the center from an open aperture. The edges, of course, are far from ideal on APS-C too, but not as bad as on the Vega-3 lens. With aperture down to F / 8 for the edges on APS-C, you can no longer be afraid, aperture up to F / 11 sharpens the sharpness well in the full frame, although the corners remain blurred (4: 3 aspect ratio). On the full frame are noticeable chromatic aberration at the edges of the frame.

Such a fierce struggle for the focal segment during the calculation of Vega-M-1, apparently, did not take place, unlike the Vega-3 lens: the field aberrations are not as great as I expected.

Bokeh Vega-M-1 is rather soft and calm. The defocus discs are uniformly illuminated and have no bright edging - a sign of well-corrected spherical aberration. This distinguishes the lens from the lurid "helios". Closer to the edge of the frame, the discs turn into lemons due to strong vignetting, while changes in the illumination of the discs are hardly noticeable (unlike Vega-3 or Vega-11).

The color rendition is slightly shifted to the warm area. The lens does not like backlight - a veil appears. In normal light, the image is contrasty, saturated and practically does not require any processing in the RAW converter.

Below are examples of photos on Sony A7s. Part of the photo is cropped to 4: 3 format.

Conclusions

At first, I reacted with distrust to Vega-M-1 after the experience of using other lenses with a similar optical design, but it turned out to be quite pleasant. The lens proved to be especially good in shooting small objects due to the large depth of field, high sharpness and pleasant pattern. A big plus is the ability to work with full-frame cameras (at least 4: 3) - the Vega-M-1 can serve as an ultra-compact near-width. For crop cameras, of course, the most preferable of these older lenses is the excellent Pentakta 30 / 2.8, but it is noticeably more difficult to adapt, and it is difficult to find a ready-made version with an installed aperture.

  • Novel

    And that's what is characteristic - for flowers, even 2.8 in most cases is not enough, it would be good to clamp up to 4, sometimes up to 5.6. But we methodically turn our nose up at 2.8 and crave 1.2, 1.0, or even 0.95. For what? To a microscopic cut, and everything else to the trash?

    • Rodion

      Yeah, that's why I prefer not even 50 / 2.8, but quite 35 / 2.8 or even 24 / 2.8 (damn Canon).

      • Novel

        Now, if the old 135 / 2.8 had a fast autofocus with its size, it would have been a hurray. On a mirrorless camera with a stub on the matrix, a set of three glasses with an emphasis on compactness, some 24-50-135 / 2.8 would be a marching ideal. Even 24/4, 50/2, 135 / 2.8 - something like that. In straight hands, it would be enough for everything.

    • Alexey

      strange conclusion. I shot full frame (5Dsr) at 24 1.4L II in full-frame portraits. The depth of field was more than enough. there was a blur of the background, the ISO did not have to be raised when there was a lack of light. so light shirik is very much needed and useful.

      • Rodion

        Well, 24 / 1.4 is like 50/2. And a portrait is not nearly a macro flower. There is enough depth of field - of course.

      • Novel

        Because you used a fast lens the way it was intended. Adequate distance from subject and in low light conditions. And from us Narid buys lenses with aperture tending to zero with one single purpose - flowers. Well, cats, yes. With a depth of field of one vibris.

        • Victor

          Xs, I took 50 / 1.2 with one goal - full-length portraits, maximum - chest-deep))

          Of course it's strange to shoot flowers on it)))

          I like flowers on long-focus telephoto lenses more, there is enough depth of field, and the background is well washed.

  • Onotole

    With this name, this camera should have been intended for selfies)))

    • Jury

      And so it was :)
