The Olympus AF 50mm f/1.8 is a classic lens. It can be used well in everyday life and for portraits. It is part of a generation of autofocus lenses for OM SLR cameras.
The focal length of the fixed focal length is specified as 50 mm. Therefore, the lens can be counted among the group of standard lenses. The fixed focal length is equipped with a maximum aperture of f/1.8. The smallest aperture is f/22. For a sharp subject, you need to keep a distance of 47 cm.
The design of the Olympus AF 50mm f/1.8 consists of six elements. These lens elements are arranged in 5 groups. Filters can be screwed onto the 49 mm thread. Suitable filters, such as ND filters or UV filters, are available from various manufacturers. Matching 49 mm filters are very easy to find. The lens weighs 170 grams. The overall length of the whole model is 3.2 cm.
The 50 mm lens can only be used on two models of the OM series. These are the OM-707 (OM-77 AF) and OM-101 PF (OM-88). This is because the settings in the lens are handled by the camera electronics. There is no focus ring or aperture adjustment option on the lens. Therefore, there is no way to use the autofocus lens on a modern SLR camera. So if you want to use an old Olympus lens with your DSLR, you should reach for an alternative specimen without autofocus.
