1. The world’s shortest standard zoom lens 
This standard zoom lens offers a zoom ratio of approximately 2.8 times to cover the wide-angle to standard ranges (for focal lengths equivalent to 27.5mm to 76.5mm in the 35mm format), which are the most frequently used ranges in general photographic applications. Thanks to its new retractable mechanism, it measures a mere 41millimeters in length in the stored position - the world’s shortest for a standard zoom lens - to assure outstanding portability in combination with today’s downsized digital SLR camera body.

2. Dependable weather-resistant construction 
This lens features a dependable weather-resistant construction with nine special seals to effectively prevent the intrusion of water into the interior. By pairing it with a weather-resistant PENTAX digital SLR camera body, the user is assured of a durable, reliable digital imaging system that performs superbly in demanding shooting settings - even in the rain or mist, or at locations prone to water splashes or spray.

3. Exceptional image rendition to accommodate latest digital SLR cameras 
Incorporating super-low dispersion glass elements and aspherical elements in its 11-element/eight-group optics, this lens effectively compensates various aberrations for high-contrast, high-resolution, fine-detailed images with minimal colour bleeding.

4. Quick-Shift Focus System 
This lens is equipped with the PENTAX-developed Quick- Shift Focus System, which allows the user to instantly switch to manual-focus operation, even when the camera’s AF system is in operation.
