 Pentax DA 18-55mm and 50-200mm lenses : Pentax Imaging Systems Division is pleased to announce the launch of two compact, lightweight zoom lenses: the smc Pentax DA 18-55mm F3.5-5.6 AL WR, and the smc Pentax DA 50-200mm F4-5.6 ED WR. Featuring a newly designed, simplified weather-resistant construction, these zoom enses offer excellent reliability in various outdoor applications - especially in rain, fog and mist. The new zoom lenses feature a simplified weather-resistant construction designed to minimize the intrusion of water and moisture into the lens barrel. With these lenses mounted on Pentax weather-resistant digital SLR camera bodies, the user is assured of improved durability and reliability during shooting in rain, fog or mist and at locations subject to a spray or splash of water.

Pentax zoom lenses with SP coating
The front surface of these lenses is treated with Pentax-original SP (Super Protect) coating, which applies a special fluorine compound to the lens surface through a vapor deposition process. This SP coating not only effectively repels dust, water and grease, but it also makes it easy to wipe off fingerprints and cosmetics.
Pentax lenses for digital SLR cameras
Pentax has optimized the characteristics of these lenses - including lens coating, curvature and positioning of optical elements - to reproduce the finest possible digital images. As a result, they are practically free of flare and ghost images, and bring out the best in the Pentax digital SLR camera bodies they are coupled with. Their image circle is also perfectly proportioned to the size of the image sensor used in Pentax digital SLR cameras, helping to reduce the camera’s overall size and weight and guarantee outstanding cost performance.
Quick-Shift focus system on the Pentax zoom lenses
After the subject is captured in focus by the camera’s AF system, the unique Quick-Shift Focus system lets the photographer instantly switch to manual-focus operation for final pinpoint focus adjustment. |
