A rare non-tube version of the Industar-22, without a focusing ring. Production Kazan optical-mechanical plant, 1949 release. Perfect condition, close to new. The focusing ring rotates 180 degrees, the minimum focusing distance is 1 meter. The aperture setting is smooth, without intermediate values from F / 3.5 to F / 16.0. The number of aperture blades is 8 pieces. Working with such a lens is very interesting and unusual, this is not some modern autofocus super-zoom for you. Has excellent sharpness and enlightenment of lenses.
