Olympus Zuiko Digital 40-150mm f/4-5.6 Lens (Four Thirds System)

This is a telephoto zoom lens manufactured by Olympus for the Four Thirds (not Micro Four Thirds) digital SLR system. The lens features a black polycarbonate exterior construction with a distinctive blue ring below the front element, a signature of the Zuiko Digital line. It is equipped with a large, reversible plastic lens hood marked 'CHINA' and an alignment arrow. The lens barrel displays focal length markings of 40, 50, 70, 100, and 150mm, with a minimum focusing distance indicated as 0.9m/2.96ft to infinity. A red mounting index dot is visible near the base. The rubberized zoom grip shows significant cosmetic wear, characterized by a heavy white 'blooming' or oxidation typical of aging rubber compounds found in older camera equipment. Despite this surface oxidation, the structural integrity of the barrel appears intact, though the overall condition would be rated as fair to good due to these surface aesthetics. This specific model was common as a 'kit' telephoto lens in the mid-to-late 2000s. The craftsmanship is standard for consumer-grade optics of that period, prioritizing lightweight design over professional-grade weather sealing or metal construction.
