Visionary Soviet lens Helios-44M-4 2/58

A fast lens manual lens with a fixed focal length of 58 mm and the luminosity is 2. The optical circuit is Biotar. It was produced at Krasnogorsk Mechanical Plant and Valdai Plant "Jupiter." There are versions with both single-layer chemical enlightenment and multi-illumination (MC added in the marking).

Helios-44M-4 is a further improvement of the Helios-44M lens. The numbering of lenses is interesting, which from 44М jumped to 44М-4, although there were no intermediate versions (-2, -3). It is a standard lens for the mirror cameras Zenith-11 Zenith-12sD, etc.

Specifications: Focal length: 58 mm
Maximum diaphragm: 2
Minimum diaphragm: 16
Number of lenses/groups: 6/4
Minimum focusing distance: 0.5 m
Center/edge resolution: 38/19 lines per mm
Number of diaphragm petals: 6
Enlightenment type: single-layer
Fastening: m42
Weight: 242 g.


Ergonomics and construct:

The copy is compact - like all standard lenses have relatively not large dimensions, made of metal and glass. The lens has a large diaphragm stroke of 2.0 to 16.0 quite enough for any type of shooting. Helios-44M-4 traditionally has a diaphragm pimple, a mechanism that closes the diaphragm to an operating value at the moment of descent or measurement of TTL exposure with an extensometer. The diaphragm is switched by steps with intermediate values.

Another difference of the lens is one small but important detail: if you twist the focusing ring to the indicator "infinity," the rear part of the lens is seen literally 1-1.5mm less than the predecessor. This means that this lens will work at infinity on later anti-aircraft, for example on Zenith-412LS.

Artistic features and examples of photos: Helios-44M-4 was installed on film cameras Zenith as a standard lens. This means its versatility on a full-frame - they can shoot a wide range of objects. From a large plan of butterfly flowers from a distance of 0.5 meters to portraits from a distance of several meters and landscapes at infinity.

The photo shows wonderful colors. The lens has excellent sharpness in the center. To the edges, it naturally decreases, but it is the "chip" of all Helios. When shooting on a large diaphragm you can see a beautiful twisted side, which gives the photos a certain charm.

Helios-44M-4 is afraid of counter light. When it hits, the picture loses contrast. If there is no direct or sidelight, the lens gives a good contrast.


Conclusion: Helios-44M-4 has good characteristics. Because of its simplicity, it is now often used as an alternative to fixed autofocus lenses on modern digital mirrors. Because of its focal length, it can be used as a portrait that blurs the back background well, has an interesting side - a very beautiful art picture.
