Photo Stats

Designed for use with Pentax digital SLR cameras with K-mount, this wide-aperture telephoto zoom lens is a new addition to the Star * high-performance lens series developed to offer the best quality and highest level of image definition.

This telephoto lens marks a new milestone in terms of image quality within the range of optics of the Star * series, both in resolution and in control of aberrations. Thanks to its design it offers a constant brightness of F2.8 and a coverage equivalent to 107-307 mm when used with a Pentax digital SLR sensor camera APS-C. This objective has a new optical coating (Aero Bright Coating II) to avoid reflections and phantom lights, and incorporates a total of 8 elements of low dispersion in its structure. In addition to 4 elements of ultra low dispersion glass and 2 ED elements of extra low dispersion, its optics includes a pair of new Super ED glass elements to effectively compensate chromatic aberration throughout the zoom range, thus offering high resolution images with excellent sharpness from end to end. Its dustproof and weather resistant (AW) body also makes it very reliable and durable in extreme outdoor conditions.

High performance lens of the Star series (*) with constant luminosity of F2.8

This telephoto zoom has been developed as a new high-performance model of the Star (*) series, which ensures exceptional image rendition with edge-to-edge sharpness, effectively reducing various aberrations to the minimum. When mounted on a digital SLR camera body of PENTAX, offers a zoom ratio of approximately 2.9X to cover a focal length from 107mm to 307mm in the 35mm format. Since it provides a large maximum aperture of F2.8 throughout the zoom range, it is ideal for beautifully out-of-focus foreground / background portraits and sports photography requiring high shutter speeds to freeze action. Its image circle is optimized to cover even the image size of 35mm format film SLR cameras. As a result, not only ensures, bright images in high resolution without compromising edge sharpness, even when mounted on a current body of PENTAX digital SLR camera, but is also able to accept future models with higher image sensors size without modifications.

The latest in optical technology


This zoom telephoto lens features the newly developed Aero Bright Coating II coating - a lens coating nanotechnology that employs a very low refraction film manufacturing process to ensure a lower light reflection than conventional Aero Bright * coating. By coupling this advanced lens coating with the high-grade HD ** multi-layer coating that reduces an average of visible-beam reflectance to less than 50% of conventional multi-layer coatings, this lens effectively reduces reflections and ghost lights in the images to the minimum, even in demanding lighting conditions such as backlight. In addition to 4 elements of ultra low dispersion glass and 2 ED elements of extra low dispersion, its optics includes a pair of new Super ED glass elements to effectively compensate chromatic aberration throughout the zoom range, thus offering high resolution images with excellent sharpness from end to end.

* The latest in technology, an original PENTAX lens coating developed from nanotechnology. A silica airgel coating layer with uniform porous structure is applied over a regular multiple coating layer to reduce surface reflections across a wide range of wavelengths and produce high quality and super sharp images.

** HD means high definition.

Weatherproof and dustproof construction (AW)


The lens has a weatherproof construction with 13 sealed parts (AW - All Weather) to effectively prevent the intrusion of water inside. By pairing with a DSLR camera with weatherproof body, a durable and reliable imaging system with excellent performance in demanding shooting conditions is guaranteed - even in rain or fog, or in places prone to water splash or spray .

New three-position switch for Quick-Shift focusing system


The lens is equipped with the Quick-Shift focusing system developed by PENTAX, which allows the user to immediately switch to manual focus operation after the subject is captured by the camera's autofocus system. In order to improve its operability, the new three-position switch has been installed, allowing instantaneous switching between the QFS / A, QFS / M and MF modes. QFS / A
