The lenses in this series represent exceptionally high optical performance and outstanding features. The Star series is designed not only to meet the current demands of digital photography but also to be prepared for future generations. Like all lenses in this line, the 11-18 mm ultra-wide-angle zoom lens delivers high-resolution and high-contrast images without blurriness at the edges and ensures excellent imaging performance even at wide open apertures.

With the introduction of this lens, the high-quality and powerful Star series now offers compact lenses with a minimum aperture of F2.8, ranging from ultra-wide-angle to telephoto, for PENTAX digital cameras.

As with all lenses in this series, special attention has been paid to usability under adverse conditions. The lens is equipped not only with seals against moisture and dust ingress but also with preparation for using a dew cap heater, significantly enhancing the usability of the lens when photographing landscapes and starry skies.
