The Olympus Zuiko Auto-T 100mm f/2.8 is a lens from Japanese production. It was developed by Olympus for the models of the OM series. It can be used directly on the analog SLR cameras with the corresponding mount. Use on a modern digital camera is partially possible with an additional adapter.
The fixed focal length comes with a focal length of 100 mm. Therefore, the lens can be counted to the group of telephoto lenses. f/2.8 is the largest aperture of the lens. Completely closed, the aperture is f/22. The lens must be focused manually. If you want the subject to be in focus, you have to keep at least 100 cm away from the subject.
