Micro Four Thirds cameras

14-150mm F/3.5-5.8 Di III (Model C001)

High-performance zoom lens in a compact body with high-grade metal finish.

June 19, 2014, Saitama, Japan - Tamron Co., Ltd. (President & CEO: Morio Ono Headquarters: Saitama City, Japan), a leading manufacturer of optical equipment launches its first high-power zoom lens designed for Micro Four Thirds mirrorless interchangeable-lens cameras.

For the past 22 years since Tamron released to the market an extremely practical high-power zoom lens (28-200mm Model 71D) in 1992, the company has endeavored to continually develop high-power zoom lenses. By actively using its long-cultivated technology, Tamron has successfully developed an epoch-making compact and stylish, high-power all-in-one zoom lens that will further accelerate the attractiveness of the Micro Four Thirds cameras in the market.

Product Highlights

  • Employing one LD (Low Dispersion) glass element, two AD (Anomalous Dispersion) glass elements, two Molded-Glass Aspherical elements and one Hybrid Aspherical element, Tamron’s new Micro Four Thirds high-power all-in-one zoom lens delivers leading-edge image quality by reducing aberrations to a bare minimum.
  • The ingenious optical design achieves a compact body with a filter diameter of just 52mm.
  • A stepping motor that is optimized to match this model provides silent, quick and accurate auto focusing.
  • The metal lens barrel exterior is available in two colors: black and silver, providing the most popular color options to match high end cameras.
  • Using a circular diaphragm*1, this lens achieves spectacular background blur effects.

*1 This circular diaphragm retains a nearly circular shape even at two stops down from the maximum aperture.

Detailed Feature Explanation

About the stepping motor

The stepping motor’s actuator allows finely tuned control of angular rotation, and since it drives the focusing mechanism directly without an intermediate reduction gear, it also provides superbly quiet performance.
