<p>This is a mid telephoto lens with the bright aperture of f/2.4 despite its compact size. It uses a glass molded aspheric lens at the 7th element to prevent field curvature, and places an ED (extra-low dispersion) glass lens at the 6th element to contain chromatic aberration. The lens is ideal for portraiture because of its beautiful blur and high-definition description. At the minimum working distance of 26.7cm, the lens delivers the maximum magnification of 0.5x for macro photography.</p>
