Canon Lens FD 135mm 1:2.5 (not authenticated)

The item presented in the photograph is a camera lens featuring a black metal and polycarbonate barrel with a heavily textured rubberized focus ring around the center section. The front element of the lens is attached with a screw-on filter, specifically a Canon 58mm SKY 1-A U.S.A. filter. The text printed around the front bezel of the lens reads 'CANON LENS FD 135mm 1:2.5'. Further down the barrel, near the mounting base, various distance scales are visible in both feet (ft, shown in orange) and meters (m, shown in white), along with aperture markings ranging from 2.5 up to 22. The physical condition exhibits some light dust accumulation and minor wear on the surfaces consistent with previous use, though no major structural damage, cracks, or severe denting are immediately apparent from this angle. The manufacturing details such as the focal length and maximum aperture are directly readable from the printed text on the lens housing. The overall design and typography are consistent with vintage manual focus photographic equipment produced during the late analog photography era, specifically matching the Canon FD mount system timeline. The attribution in the item name rests directly on the legible text and brand markings printed on the barrel and filter ring. As this is an evaluation based solely on a photographic image, the item remains unauthenticated and its internal mechanical or optical functionality is unverified.

Based on what I can see in the provided photograph, the item appears to be a vintage camera lens bearing markings consistent with a Canon FD 135mm 1:2.5. The barrel shows light surface wear and minor dust accumulation, but no obvious cracks or severe structural damage are visible from this angle. However, I cannot verify from a photo whether the internal optical elements are free of haze, fungus, or separation, nor can I test the mechanical operation of the focus and aperture rings, which would need physical inspection to confirm. My value estimate of $60-120 assumes the attribution to Canon is correct and that the internal mechanics and optics are in functional working order. Vintage manual focus lenses of this type generally experience steady demand among analog photography enthusiasts and hobbyists. If this item were to turn out to be a non-functional unit, a replica, or a generic copy lacking the optical assemblies of the presumed brand, the value would decrease significantly, likely dropping to nominal parts-value of $15-30. To confirm authenticity and optimal working condition, a physical examination by a qualified camera technician, alongside operational testing of the aperture blades and glass clarity, would be necessary.
