COSINA CO., Ltd. Joins the Micro Four Thirds System Standard Group

Micro Four Thirds

Announced jointly by Olympus Imaging Corporation (President Masaharu Okubo) and Panasonic Corporation in 2008, the Micro Four Thirds System standard has rapidly grown in popularity. Now, support for the standard is expanding with the decision of COSINA CO., Ltd to join the Micro Four Thirds System standard. To coincide with this announcement, the company is releasing interchangeable lenses compliant with Micro Four Thirds System standard.

With COSINA CO., Ltd. coming on board, consumers will now be able to take advantage of the company's unique traditions and advanced optical technology as it will now be possible to use Voigtländer and other renowned lenses with any camera compliant with Micro Four Thirds System standard.

As the company responsible for initiating both the Four Thirds System and Micro Four Thirds System standards, Olympus Imaging Corporation will continue to develop and enhance the product lineup for both standards to meet the diverse needs of our customers.

Outline of the Micro Four Thirds System standard

The Micro Four Thirds System standard was designed and developed to maximize the performance potential of digital imaging technology, and to extend the benefits of the Four Thirds System standard for digital camera systems. When compared to the Four Thirds System standard, the primary distinguishing features of the Micro Four Thirds System standard are:

  1. Approximately 50% shorter flangeback distance (mount-to-sensor distance)
  2. Lens mount outer diameter approximately 6mm smaller
  3. Electrical contacts in mount increased from 9 to 11
Image sensor diagonal dimensions are the same for both Four Thirds System and Micro Four Thirds System standards.

The Micro Four Thirds System standard enables users to enjoy the same high image quality of the Four Thirds System's 4/3-type image sensor in a much more compact body, and also take advantage of significantly more compact lenses, particularly in the wide-angle and high-power zoom range. The Four Thirds System standard offers the benefits of compact, lightweight performance, and the new Micro Four Thirds System standard takes this still further to enable development of ultra-compact interchangeable lens type digital camera systems unlike anything seen before. The new Micro Four Thirds System standard also incorporates a greater number of lens-mount electrical contacts for the support of new features and expanded system functionality in the future.
