The Olympus Zuiko Auto Zoom 75-150mm f/4 is a lens. It was developed for the OM system
and was one of the first zoom lenses for the lens mount. The production took place in a factory of the traditional company in Japan.
The focal length at one end is 75 mm and at the other end 150 mm. This gives a zoom factor of 2. The maximum aperture is f/4 throughout. The focus has to be adjusted manually every time with this model. A minimum distance of 160 cm from the subject must be maintained for sharp images.
The Olympus Zuiko Auto Zoom 75-150mm f/4 can be used on cameras with Olympus OM mount. Use with an adapter is also possible. Thus, it can also be used on digital cameras.
The zoom lens is composed of 15 elements in 11 groups. A 49 mm filter lens, e.g. an IR filter, can be screwed in front of the lens. The lens weighs 450 grams.
