Soviet Jupiter-11 lens in excellent, fully functional condition! Made in 1962 at the Kazan Optical and Mechanical Plant. The lens has a classic Sonnar (from Sonnar) scheme of 4 lenses in 3 groups. The number of aperture blades is 12 pieces and allows you to get smooth bokeh. The focus ring rotates 360 degrees for smooth focusing. In the photo it gives a soft, contrasting picture, great for portraits (see photo examples). With the help of an adapter, it is perfect for modern mirrorless cameras.
