Zuiko digital specific lenses are designed specifically for digital capture with smart technology that delivers edge-to-edge sharpness with reduced distortion and shading. The lenses are designed to perfectly match the imager so light strikes the sensor directly, ensuring rich, accurate colors, sharp contrasts, and bright images even at the edges. Zuiko digital specific lenses deliver higher resolutions, faster aperture speeds and focusing, and more compact sizes than equivalent 35 millimeter lenses.

Zuiko digital specific lenses are based on the new Four Thirds System, an open standard for digital SLR cameras and interchangeable lens systems that utilize a 4/3-type image sensor. The Four Thirds System is designed to achieve an optimal balance between image quality, camera and lens size, and system expandability. The system maximizes the performance of image sensors and lenses with a 100 percent digital-from-the-ground-up design.
