16-45 mm SMC-ED DA Digital Series Zoom Lens
The perfect companion lens for the *ist D digital SLR. The compact, high-performance, interchangeable SMC Pentax DA 16mm-45mm f/4 ED AL lens features a three-times zoom ratio with focal lengths covering ultra-wide to moderate-telephoto ranges for the angle of view equivalent to 24.5mm-69mm in the 35mm format. The DA-Series Lens lens features a responsive Quick-Shift Focus System that allows photographers to instantly switch the focus mode from auto to manual with a slight twist of the focus ring. Coupled with a simple, functional design and the elimination of an aperture ring, this new mechanism considerably improves the camera's operability. The lens also incorporates an Extra-low Dispersion (ED) glass lens element and two aspherical lens elements for true-to-life image reproduction and overall size reduction. The image circle in DA-series lenses, including the SMC Pentax DA 16mm-45mm f/4 ED AL, is designed to perfectly match the 23.5mm x 15.7mm size of the CCD used in Pentax digital SLRs, optimizing camera performance. The new design also contributes to a drastic reduction in size, weight and production cost, compared to 35mm-format counterparts with similar specifications....
