The Olympus AF 35-105mm f/3.5-4.5 is a lens from the supplier Olympus. It was introduced in the 1980s. It was probably produced in a factory in Japan.
The specimen comes with a zoom and has a zoom ratio of 3. The focal length range goes from 35mm to 105mm. f/3.5 or f/4.5 is the largest aperture available. The stated closest focusing distance in “Close Focus Mode” is 85 cm. Otherwise, the value is 1.5 m.
The lens can be connected to cameras with Olympus OM mount. However, it should be noted here that you can only really use it with two models. Since it is an autofocus lens, the focus setting is made by the camera. There is no manual focus option. The aperture is also changed by the camera electronics.
Therefore, the lens can only be used with the OM-707 (OM-77 AF) and the OM-101 PF (OM-88). Using it on the other Olympus SLR cameras does not make sense. Also, there is no adapter to use the zoom lens on a modern digital camera.
The Olympus AF 35-105mm f/3.5-4.5 is composed of fourteen elements in thirteen groups. A 55mm filter lens, such as an IR filter, can be screwed in front of the lens. The weight is listed at 460 grams and the length at 8.4 cm.
