Designed for exclusive use with Pentax KAF-mount digital SLR cameras including the *ist D and the *ist DS digital SLRs, the Pentax DA 50-200mm f4-5.6 ED lens offers 4x zoom coverage in the telephoto range. Further, the lens features an angle of view from 31.5 degrees to 8.1 degrees (equivalent in focal length from 76.5mm to 306mm in the 35mm format). The lens also incorporates an Extra-low Dispersion (ED) glass lens element (11-element/10-group optical construction) and two aspherical lens elements for true-to-life image reproduction and overall size reduction. The image circle in DA-series lenses is designed to perfectly match the 23.5mm x 15.7mm size of the CCD used in Pentax digital SLRs to optimize 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. Other features include: Compact dimensions with minimal aberrations Responsive Quick-Shift Focus System allows instant shift from AF to MF Comes with a lens hood to minimize flare and ghost images 52mm filter size Weighs 9.2 ounces Measures 2.6 x 3.1 inches (diameter x length)
