PENTAX DA 18-55mm F3.5-5.6 AL WR
The Pentax 18-55mm F/3.5-5.6 AL WR is a zoom lens with a simplified weather-resistant construction design offering excellent reliability in various outdoor conditions. This standard zoom lens covers focal lengths equivalent to 27.5mm wide-angle to 84.5mm medium telephoto (in the 35mm format). Incorporating a high-performance aspherical (AL) optical element and a super-low-dispersion glass optical element in its optics, it assures outstanding image resolution and remarkable brightness, even at the edges, while effectively compensating various aberrations.
The front surface of this lens has been treated with Pentax' original SP (Super Protect) coating, which applies a special fluorine compound to the lens surface through a vapour deposition process. This SP coating not only repels dust, water and grease effectively, but it also makes it easy to wipe off fingerprints and cosmetics.
Pentax has optimised 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. 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. Another feature of the 18-55mm F/3.5-5.6 AL WR is its durable and dependable metallic lens mount. A lens hood with a PL (polarising filter) window is included as a standard accessory.
