Auto MC Zoom f=80-200mm 1:4.5 Camera Lens

This is a vintage camera zoom lens, specifically marked 'Auto MC Zoom f=80-200mm 1:4.5' with a serial number 'No. 919917'. The lens has a filter thread size of 55mm, indicated by '55Φ'. The 'MC' designation likely stands for 'Multi-Coated,' a common feature in lenses from the mid-20th century onwards, aiming to reduce flare and ghosting and improve light transmission. The 'Auto' marking suggests it may have some form of automatic diaphragm control or compatibility with cameras offering aperture-priority or program modes. The focal length range of 80-200mm at a constant maximum aperture of f/4.5 indicates a telephoto zoom lens, suitable for a variety of photographic situations from portraits to sports and wildlife. The physical construction appears to be predominantly black metal, typical of camera lenses from its likely era, which would be late 1970s to 1980s based on the markings and general design. The front element shows visible dust and possibly some smudges or internal particles, indicating a need for cleaning and potential service. While the image only shows the front of the lens, the robust metal construction generally implies good build quality for its period. No significant scratches or dents are visible on the outer barrel, but the condition of the optical elements (front and rear) would require a more in-depth inspection to assess fully. The engraved markings are clear, suggesting durability in their application. This type of lens would typically be used with SLR cameras of that period, often requiring a specific lens mount (e.g., K-mount, M42, FD, MD etc.), which is not visible here. The presence of dust on the front element affects its immediate usability and potential image quality.
