This is a Canon zoom lens, the EF 75-300mm f/4-5.6 III USM. The lens is clean with no mold or haze. It looks clear even under LED light. Please excuse any minor dust particles. I have confirmed that it functions properly on a camera body, including the aperture blades and autofocus. The zoom ring is also smooth. It is an EF mount lens. The exterior may have some minor scratches, but it is generally in good condition.
