This lens covers a wide zoom range and features Pentax's latest lens technology, including the Quick-Shift focus system, SP (Super Protect) coating, and a DC motor for the SDM focusing system. When this lens auto-focuses, the external focusing ring does not move, allowing for comfortable holding and fine manual adjustment on the fly. The lens also features an aspherical element, internal focusing, and extra-low dispersion element, and weather sealing to compliment the weather sealing of the K-5. The aperture blades are rounded to help render a very smooth bokeh. Finally, the lens hood also features a filter window for easy use of CPL filters.
