OLYPMUS lens interchangeable digital SLR cameras are a completely new digital SLR camera system all based on the development philosophy “exclusively digital”, incorporating the “Four Thirds System”, and are designed and developed to extract the most out of digital camera characteristics.

The “Four Thirds System” has freed itself from pre-existing 35mm SLR film camera lens systems, basing designs on digital-exclusive exchangeable lenses specifically developed to meet the properties necessary for optics used in digital cameras. It is a standard created to allow lenses to reach the maximum potential of the imaging device in order to deliver the highest quality in images, while providing mobility and ease of handing as well.
