Auto Zoom Lens Appraisal

Kenlock Auto Zoom Camera Lens

This item is a vintage Kenlock Auto Zoom camera lens, presented in a cylindrical form factor typical of photographic lenses. The lens is predominantly black with a matte finish, suggesting a metal or high-quality plastic construction. The main barrel is textured with a fine, crosshatch knurling pattern, which provides a secure grip for manual adjustments. Markings visible on the lens include 'KENLOCK AUTO ZOOM' emblazoned in white lettering on the frontmost ring. Below this, there are distance scales marked in both feet and meters, with numerical values such as '20', '30', '70' (feet) and '7', '10', '25' (meters), as well as an infinity symbol. Further down the barrel, there is a focal length scale with numbers like '85' and '100'. An aperture ring is also visible, with f-stop values such as '22', '16', '11', '8', '5.6', and '4.5', indicated by a yellow triangular marker. The overall construction appears robust, suggesting a professional or enthusiast-grade optical instrument from the mid to late 20th century. There are no significant visible condition issues such as major scratches, dents, or fungus within the glass, though detailed internal inspection is not possible from the image. The knurling appears intact and well-defined, indicating reasonable care. This lens likely belongs to a period when manual focus and zoom control were standard, emphasizing quality craftsmanship and mechanical precision.
