The Olympus Auto-S 50mm f/1.2 is a lens from Japanese production. It was introduced in the 1980s and developed for the OM system SLR cameras.
The focal length of the lens is specified as 50mm. Therefore, it belongs to the group of normal lenses and can be used for versatile subjects. The lens is equipped with a maximum aperture of f/1.2. The smallest aperture that can be set is f/16. The focus of this model is set manually. For sharp images, do not get closer than 45 cm to your subject.
The lens can be used on analog cameras with Olympus OM mount. It can also be used on modern digital cameras. For this, an adapter is needed, with which OM lenses can also be used on a different bayonet. For example, there are corresponding accessories for Canon’s EOS cameras. If it is a camera with crop sensor, the image detail is somewhat smaller, depending on the sensor size. To capture the full power of the 50 mm, you need a DSLR with a full-frame sensor.
Built up, the Olympus Auto-S 50mm f/1.2 consists of seven elements in six groups. A 49 mm filter lens, such as an Orange filter, can be attached in front of the lens. The lens weighs 285 grams. The overall length is 4.3 cm. The lens is well suited for travel use, indoor shooting and portrait photography.
