Olympus OM-SYSTEM ZUIKO MC AUTO-T 1:4.5 300mm Olympus Zuiko 300mm 4.5 Although I have selected the Four Thirds mount due to the absence of the appropriate category, this is an Olympus OM mount lens. This is a telephoto lens for Olympus film SLR cameras. It was purchased over 40 years ago. I used it when I first bought it, but it has been stored at home in a storage room for over 30 years. Please understand that this is a used item.
