Functionality: In practically pristine condition: used only a couple of times, carefully stored as a collector's item at room temperature and humidity. It is fully functional and operational – the lens is clean inside, focusing and aperture operate smoothly, pleasantly, and without problems. The aperture blades are dry and free of excess grease. The lens has been tested. The photos are excellent. My highest recommendations))) The Jupiter-37A 3.5/135 is a legendary Soviet short-focus telephoto lens (portrait lens) of the Sonnar type, known for its high sharpness, excellent contrast, and beautiful bokeh. Its maximum aperture and 135mm focal length make it ideal for portraits, especially the multi-coated (MC) version. It is reliable, compact, and versatile. Key specifications and features: Type: Prime telephoto lens. Focal length: 135mm. Aperture: Mount/Thread: Typically M42x1, which simplifies installation on modern cameras via an adapter. Optics: 4 elements in 3 groups (Sonnar type). Aperture: 12 blades providing a very round aperture and soft bokeh. Minimum Focusing Distance (MFD): 1.2 meters.
