The Olympus Zuiko Auto Fisheye 16mm f/3.5 is a lens from the Olympus brand. It comes from Japanese production. It is the widest-angle full-frame fisheye lens for the OM system.
The lens comes with a fixed focal length of 16 mm. It therefore belongs to the group of fisheye lenses. The maximum large aperture of the fixed focal length is specified as f/3.5. The smallest aperture can be set to f/22.
The focus has to be adjusted manually every time with this model. You have to keep a distance of 20 cm for sharp pictures. According to the manual, the viewing angle is specified as 180 degrees diagonally.
You can't attach your own filter to the fisheye lens. But there is a built-in turret for three filters (UV, yellow, orange).
The 11 elements of the Olympus Zuiko Auto-Fisheye 16mm f/3.5 are arranged in 8 groups. It is very compact in itself and thus cuts a good figure on the compact OM-system SLR cameras. The weight is specified at 189 grams.
