Soviet Lens INDUSTAR-61 L/D 2.8/53 mm, mount M39, for Fed, Zorki, *130

Description: Item details Quantity: 1 piecesWeight: 130 grams Description Soviet Lens INDUSTAR-61 L/D 2.8/53 mm, mount M39, for Fed, Zorki. Suitable for all modern cameras with M39 mount. ---------------------------------- Industar-61 - Enlightened lens of medium aperture with lanthanum glass. The calculation was made by the well-known Soviet opticians Academician G. Slyusarev and V. Sokolova in accordance with the trends in the use of the latest types of optical glass with rare earth elements. Both positive lenses use STK-6 lanthanum superheavy crown. Such glass has a high refractive index, allowing to obtain the same optical power with less surface curvature and, as a result, reduced aberrations. Compared to earlier Industars with a very fast drop in resolution towards the edges of the frame, the new lens provides more even field sharpness. Produced in different frames for different types of small-format photographic equipment. On frames of various versions, the focal length could be indicated as 50, 52, 53 and 55 mm, although its exact value is 52.42 mm. The four-lens Industar-61 has almost the same resolution as the six-lens Helios-81. It was used as a standard for the FEDs and as a replacement for the Zeniths. The designation "D" means the version for rangefinder cameras, and "Z" - for SLR. In the mirror version, the frame could be pulled out strongly, allowing macro photography at a distance of up to 0.3 meters without extension rings. For excellent sharpness and high contrast, in many cases, photographers preferred the Industar-61 L / Z to the regular Helios-44. In the USSR, it was produced at three factories.
