The Pentax 01 Standard Prime Lens for Q Camera System (47mm Equivalent Format) is a focal length equivalent to 47mm in the 35mm format. Since it offers a natural perspective similar to that of the human eye, it can be used as a multipurpose, daily-use standard lens for many different subjects, including landscape and portraiture. With maximum aperture of F/1.9, it not only performs superbly in dim locations, but also makes it easy to throw the background out of focus. Incorporating two high grade aspherical optical elements, this lens compensates various aberrations to a minimum and produces beautiful, high resolution images that are bright and crisp even at the edge of the image field. .
