Olympus Digital SLR Lenses

Olympus has a long history in making fine lenses and its camera systems using the Olympus OM mount were used widely by photographers throughout the latter part of the 20th century. In 2003 Olympus decided to take a new approach to the production of digital SLR cameras and helped form the Four Thirds system with other manufacturers.

The Four Thirds system uses a sensor which has an aspect ration of 4:3 and measures only 13 x 17mm. This allows for the creation of smaller cameras and lighter more compact lenses which can be optically superior to systems using an APS-C size sensor. More recently, Panasonic and Olympus have taken the concept of a small camera system with interchangeable lenses a step further with the creation of the Micro Four Thirds system.
