Olympus Imaging Corporation (Olympus Imaging) and Matsushita Electric Industrial Co., Ltd. (Panasonic) have announced joint development of technologies and devices for the 'Micro Four Thirds System standard'.
In a statement, both companies said that this new standard extends the benefits of the Four Thirds System standard for interchangeable lens type digital camera systems by enabling dramatic reductions in size and weight. Under the terms of an agreement between the two companies, they will work jointly toward commercial production of significantly lighter and more compact interchangeable lens type digital camera systems.
When compared to the Four Thirds System standard, the primary distinguishing characteristics of the Micro Four Thirds System standard are an approximately 50 per cent shorter flangeback distance (mount-to-sensor distance), 6mm smaller lens mount outer diameter, and electrical contacts in mount increased from 9 to 11. The image sensor diagonal dimensions are the same for both Four Thirds System and Micro Four Thirds System standards.
The companies say that the Micro Four Thirds System enables users to enjoy the high image quality benefits of the Four Thirds System's 4/3-type image sensor in a much more compact camera body, and also take advantage of significantly more compact lenses, particularly in the wide-angle and high-power zoom range.
The Four Thirds System offers compact, lightweight performance, and the new Micro Four Thirds System will take this even further by making it possible to develop ultra-compact interchangeable lens type digital camera systems unlike anything seen before. The new Micro Four Thirds System also incorporates a greater number of lens-mount electrical contacts, enabling support for new features and increased system functionality in the future.
Use the same lenses
In addition, users will be able to mount their existing Four Thirds System lenses on Micro Four Thirds System bodies via an adapter.
Moving forward, Olympus Imaging and Panasonic will jointly develop relevant technologies and devices for both Four Thirds System and Micro Four Thirds System standards, and will develop and introduce standards-compliant products in accordance with their respective business strategies.
While continuing to develop Four Thirds System interchangeable lens type digital camera system products, Olympus Imaging will also develop a range of Micro Four Thirds System lenses and accessories, and Micro Four Thirds System camera bodies that are even smaller and slimmer than the light, compact, and widely acclaimed Olympus E-410 and E420.
While continuing to develop Four Thirds System interchangeable lens type digital camera system products, Panasonic will also develop a new generation of compact, lightweight, interchangeable lens type digital camera system products, including ultra-portable camera bodies, interchangeable lenses, and related system accessories.
