This is an Olympus Pen D3 camera. Released in 1964, it's a half-frame camera featuring a large-aperture F1.7 lens. Despite its compact size, it allowed for serious photography and was popular among camera enthusiasts at the time. The Olympus Pen D3, being a half-frame camera, allows you to take twice as many photos per roll of film. This allowed for more photos while keeping costs down. It also uses a lens shutter, enabling serious photography despite its compact size. Condition: Has scratches and stains. Please purchase with the understanding that this is a vintage camera. The shutter and film advance work without issue. If there are any problems, please message me before rating the item.
