Specifications
Although its focal length is twice as long, this 100mm lens is approximately the same size (telephoto ratio 0.93) and weight as a conventional standard 50mm lens. However, because of its 24° angle of view, it produces images twice as large. It has been designed to deliver the same high resolution and contrast as a standard lens and a moderate telephoto perspective. Accepts a 49mm filter. • Telephoto Ratio Telephoto ratio is derived by dividing the distance from the front vertex of a lens to the film plane by the focal length. The smaller the telephoto ratio, the smaller the total length of the lens. • Angle of View The total subject area which can be photographed by a particular lens is expressed as an angle. Though there are three types of angles which can be measured (based on horizontal, vertical, and diagonals of the film frame), the lens expressive capabilities must be designed to cover the widest angle in the diagonal direction.

Although its focal length is twice as long, this 100mm lens is approximately the same size (telephoto ratio 0.93) and weight as a conventional standard 50mm lens. However, because of its 24° angle of view, it produces images twice as large. It has been designed to deliver the same high resolution and contrast as a standard lens yet it yields a better perspective that is ideal for portraits and all other situations where a moderate telephoto focal length is required. Accepts 49mm filter. The OM-System interchangeable lenses range from 8mm fisheye to 1000mm telephoto and also include a variety of unique and special purpose lenses. The Olympus OM-System was developed to provide both the advanced photographer and the scientist with the world's most versatile and sophisticated 35mm photographic system.
