The OM-System interchangeable lenses range from 8mm fisheye to 1000mm telephoto and also include a variety of unique and special purpose lenses.
	ZUIKO lenses, manufactured by Olympus, have long enjoyed a world-wide reputation for excellence. Building upon this accumulated experience and employing the most up-to-date technologies such as computerized design, image evaluating simulation based on Modulation Transfer Function, etc., the task force of Olympus engineers has produced a new generation of superb lenses.
The lenses which emphasize close distance ability utilize a group of correcting elements that automatically compensate for aberrations created at close distances, maintaining unusually high performance. Careful attention was paid to color balance, including special coatings applied to certain lens surfaces. Efforts were concentrated on shortening the overall length to achieve the worlds most compact and lightweight lens designs, permitting handheld photography even with super telephotos.
	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.
	Although an SLR with a standard lens can be used with good results for general close-up photography, one lens can never be expected to satisfy all the needs of the expert in the field. Usually lenses are designed to deliver best performance at specific focusing distances. Because of this, the lens quality inevitably falls off as the distance of the subject changes.
Most lenses are optimized for best performance at infinity, but in practice, for example, a standard lens performs well up to distances as close as 1m from the film plane. However , as the focusing distance becomes closer, the magnification of the image increases to such a great extent that it becomes increasingly difficult for the lens to deliver high resolution.
