The Olympus Zuiko Auto-Macro 50mm f/2 is a lens from the supplier Olympus. It was built in a factory in Japan.
The manufacturer specifies the focal length as 50mm. The lens is equipped with a maximum aperture of f/2. When closed, the aperture is f/16. The focus of this model is set manually. The closest focusing distance is specified at 24 cm. The magnification is 1:2, and 1:1 is also possible with a bellows. Of course, you can also use the lens for “normal” photography.
The lens has an Olympus OM mount. SLR cameras with this mount can be used together with it. Through an adapter, it is also possible to use it with a modern digital camera, which of course does not require film. If it is a full-frame camera, the lens naturally corresponds to a modern 50 mm lens. If it is a crop sensor, the crop factor is added, depending on the size.
The number of elements of the Olympus Zuiko Auto-Macro 50mm f/2 is 9. These are arranged in 7 groups. A 55mm filter lens, such as an Orange filter, can be screwed in front of the lens. There is no need for a lens hood, since the front element is deep in the mount. The weight of the lens is listed at 320 grams. The overall length is 5.5 cm.
