Item details Quantity: 1 piecesTotal Weight: 248 grams. Description Soviet Lens Helios 44M-4 1:2/58 mm, mount M42, for Zenit, made in USSR. Manufactured at the Jupiter plant in Valdai. ———————————- Helios-44 is a Soviet photo lens of the Helios family, created on the basis of the German Zeiss Biotar 2.0/58 and produced from 1958 to 1999 in different versions as a standard lens for different types of small-format SLR cameras. One of the most popular photo lenses in the world. Initially produced at the Krasnogorsk Mechanical Plant and MMZ, and in the late 1980s, production was moved from Krasnogorsk to the subsidiary Valdai plant Jupiter. CJSC Jupiter Plant is a large machine-building enterprise located in the city of Valdai, Novgorod Region. Specializes in the production of optical instruments. Helios-44M In terms of mass production, this version is not inferior to the Helios-44-2, and was used as a standard lens on all Zenit cameras with a push-button or jumping diaphragm drive. The order of the chief engineer of KMZ on preparation for serial production of the lens was signed in February 1972. The first batches were intended for the Zenit-EM camera. The letter “M” in the name means jumping (“blinking” or “twinkling”) diaphragm. In early versions of the lens, the diaphragm consists of 8 blades, and in subsequent modifications 44M-4 – 44M-7 their number was reduced to 6. After the appearance of the following models of photographic equipment with a drive for such a diaphragm, for example, “Zenit-TTL” and “Zenit-19”, the production of the lens was expanded to two more factories in Minsk and Valdai. The widespread use of multi-layer lens coating in the world prompted designers to implement it on Soviet lenses. The first in the series to receive such an enlightenment in 1987 was the “MC Helios-44M-4”, the production of which was launched at KMZ simultaneously with the bayonet “MC Helios-44K-4”. Lens “MC Helios-44M-6” At the “Jupiter” plant, mass-produced lenses were divided into subtypes: “Helios-44M-5”, “Helios-44M-6” and “Helios-44M-7” according to the actually measured value of the resolution. Marking was done after quality control checks in such a way that the value of the number depended on the level of quality and resolution. Thus, the sharpness of the lens “Helios-44M-7” is higher than “Helios-44M-5”. The minimum values of resolution according to technical specifications were (center/edge): “MC Helios-44M-5” – 40/20 lines per mm; “MS Helios-44M-6” — 45/25 lines per mm; “MS Helios-44M-7” — 50/30 lines per mm; Compared to previous modifications of “Helios-44” with manual aperture drive, all versions with the “M” index have a number of features. The main one is the impossibility of smooth adjustment of the aperture due to the ring being fixed at discrete values. In addition, without an aperture drive in the camera, it can be closed to the working value only by a special switch on the frame, installed as a repeater and for the possibility of using it with older Zenit models. On the Helios-44M-4, this switch was excluded from the design, leaving the aperture operable only with cameras equipped with a drive pusher. Nevertheless, prototypes of such lenses with an M/A selector are known. Starting with this model, the rear segment was increased for compatibility with the larger mirror of new cameras. For installation on modern cameras, for example with a Canon EF bayonet, adapters with a flange that locks the aperture pusher are available. All lenses MS 44m-4, MS 44m-5, MS 44m-6, MS 44m-7 (Jupiter plant) are identical in appearance. The difference between them is mainly only in the resolution of the optics. Lenses with a mounting thread M42 (M42 X 1/45.5), such as the lens from this lot, are very easy to use on almost any modern digital cameras (both SLR and mirrorless), for this it is enough to choose the right adapter. No additional actions to remake the lens are required. ———————————- The buyer will receive exactly the same item as in the photo. Come visit us again. Thanks and Regards.
