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

This photographic equipment consists of a telephoto camera lens housed in a black metal and polycarbonate barrel with a heavily textured rubberized focus ring around the central body. The physical design features distinct markings printed in white and orange around the lens components. Specifically, text along the front filter ring clearly reads 'CANON LENS FD 135mm 1:2.5', and an attached filter reads 'Canon 58mm SKY 1-A U.S.A.'. Closer to the mounting end, numeric distance scales in both feet and meters are visible alongside aperture values ranging from 2.5 up to 22. The lens appears consistent with vintage manual focus photographic gear produced during the late 20th century. The external condition shows minor dust accumulation and standard handling wear on the metal and rubber surfaces, but no major structural damage or heavy scratching is immediately apparent from this angle. The identification rests primarily on the clearly legible branding and technical specifications printed directly on the lens barrel, though the physical item remains unauthenticated and has not been tested for mechanical or optical functionality.

Based on what I can see in the photograph, the equipment bears markings consistent with a vintage Canon FD 135mm f/2.5 manual focus telephoto lens, complete with a Canon 58mm SKY 1-A filter. The external barrel displays standard handling wear and minor dust, but I can't verify internal optical clarity, fungus, haze, or mechanical functionality from a photo alone. Would need physical inspection to confirm whether the aperture blades and focus helicoid operate smoothly. The estimated value range of $60-120 reflects typical secondary market behavior for vintage manual focus lenses of this type under the assumption that the branding is accurate. However, this valuation depends entirely on physical authentication and testing. If the item were found to be a non-functional replica, heavily damaged internally, or lacking the expected optical performance, the value would drop significantly toward nominal parts-only pricing. To confirm authenticity and overall condition, an in-person examination by a qualified camera technician or vintage optical expert would be necessary, along with practical testing on a compatible camera body.
