For the opportunity of MS Helios-77M 1,8 / 50 lens review Many thanks to Vadim Shkurat, who sent me a lens from another area for review.

Overview of MS Helios-77M 1,8 / 50
MS Helios-77M 1,8 / 50 is a very interesting lens. Firstly, the presence of multi-layer enlightenment is very strangely indicated in his name, for which the combination of letters 'MS' is responsible in the name. Usually МtionСLoyal enlightenment is referred to as 'MC'. Soviet optics 'renowned' for its unique ability to confuse names, especially when translating or transliterating. Personally, I am amused by the name of the lens. Vega-12B (a mixture of Cyrillic and Latin letters).

Secondly, I would like to draw your attention to the fact that on my MS Helios-77M 1,8 / 50 there is no manufacturer designation, most likely this is an export version of the lens. Also, most likely MS Helios-77M 1,8 / 50 is a copy or modification of the lens MS HELIOS-77M-4 1,8 / 50. Who has additional information, add it in the comments.

The lens twists the background very strongly, has excellent sharpness, holds back and side light well. As for me, this is one of the best Soviet fifty dollars. If you find one or MS Helios-77m-4 1,8 / 50 - I highly recommend purchasing.

Focusing on the lens is smooth. The focusing ring rotates 180 degrees, while focusing the front lens does not rotate, and the trunk of the lens lengthens by 1 cm. The minimum distance, as for many fifty-fifty dollars, is 45 centimeters. The lens has a focus distance scale for accurate focusing and a depth of field scale. Focusing ring metal. In general, the lens is very well assembled, although the frame near the front lens on my copy is plastic and slightly backlash. The lens uses a 52mm diameter for the front light filter. The frame of the case is made in classic colors for the latest lenses of the Helios family.

The aperture can be set from f / 1.8 to f / 16. The number of aperture blades is 6 pieces. It is a pity, if the lens had a round multi-blade diaphragm, it would not have a price. The aperture of the lens is blinking type. Only automatic iris control is available. For use on modern digital cameras, the aperture must be locked in order to gain manual control over its control.

My copy is serial number 92029111. Most likely it is 1992 production. Enlightenment on the lens is greenish, most likely enlightenment on MS HELIOS-77M-4 1,8 / 50 and MS Helios-77M 1,8 / 50 are slightly different.

How to use with modern cameras?
Lenses with mounting thread M42 (M42 X 1 / 45.5), such as the lens from this review, are very easy to use on almost any modern digital camera (both SLR and mirrorless), for this it is enough to choose the right adapter (adapter). You do not need to carry out any additional steps to modify the lens.
The cheapest adapters can be found aliexpress.com... There are adapters (adapters) with a chip that provide more convenience during shooting, usually chips are used to confirm focus and / or metering exposure, and form the correct EXIF. The chip does not affect the image quality in any way.
For some SLR cameras (for example, Nikon F) it is necessary to use adapters with a corrective lens, which allows correct focusing at all focusing distances. For any mirrorless camera, such a lens is not needed, and the adapter is a simple decorated hollow metal tube with an appropriate mount.

Personal experience
I really liked the MS Helios-77M 1,8 / 50. MS Helios-77M 1,8 / 50 lenses, MS HELIOS-77M-4 1,8 / 50 и MC HELIOS-77M-4 50mm 1: 1,8 twist the background very much.

MC HELIOS-44M-5 58mm 1: 2 and MS Helios-77M 1,8 / 50
Conclusions:
MS Helios-77M 1,8 / 50 is an excellent fast prime lens. The distant shot in the out-of-focus area spins very strongly. Recommend.
Familiarity with the Soviet Helios brand lenses I recommend starting with an inexpensive and common lens Helios-44-2 2/58 (aka HELIOS-44-2 2/58). The following links can look at modern lenses Zenitar и HELIOS.
