Press Release:

Two new smc DA* (DA Star) lenses from Pentax enable high-performance, top-quality telephoto and medium-telephoto zoom

September 22, 2008 - PENTAX U.K. launches two high-performance interchangeable lenses for the smc PENTAX-DA* (DA Star) series. These lenses are designed exclusively for use with PENTAX digital SLR cameras to deliver top-quality digital images. The smc PENTAX-DA* 60-250mm F4ED[IF] SDM is a versatile telephoto zoom lens offering a high zoom ratio, while the smc PENTAX-DA*55mm F1.4 SDM is a compact medium-telephoto lens offering a large maximum aperture.

High image quality
The two lenses are the newest members of the exclusive DA Star series and are designed to deliver the top optical performance of all PENTAX interchangeable lenses. Combining a host of advanced technologies including super-low-dispersion optical elements, extra-low dispersion (ED) optical elements and PENTAX-original lens coatings, they assure outstanding image distinction with clear, high-contrast images, even at the edges of the image field.

Dust/water-resistant construction
Featuring a set of special seals, the lenses feature a reliable dust-resistant, water-resistant construction to prevent intrusion of dust, water and moisture into the lens body.

Quick-Shift Focus system
The PENTAX-invented Quick-Shift Focus system allows instant switching to manual-focus operation, after the subject is captured in focus by the camera’s autofocus system.

SP coating to block dust and stains
The front surface of the optics is treated with the PENTAX-original Super Protect (SP) coating. Applying a special fluorine compound to the lens surface through a vapour deposition process, this coating effectively repels dust, water and grease, making it easy to wipe off annoying stains such as fingerprints and cosmetic marks.

Digital SLR-exclusive optical design
Thanks to a combination of special lens coatings, ideal curvature and best positioning of optical elements, these lenses are designed to optimise digital imaging characteristics, while effectively minimising flare and ghost images. Their image circle is perfectly proportioned to the image-sensor size of PENTAX digital SLR cameras. Despite their large maximum aperture, they are designed to be compact and lightweight to enhance manoeuverability and operability.
