This lens, which is a member of Sony's prestigious G Master series, is made to correct a broad range of chromatic and spherical aberrations in order to produce remarkably high resolution and sharpness. An XA element with exceptional surface precision is one of the three aspherical components integrated into the lens design, and it effectively reduces astigmatism, field curvature, coma, and other monochromatic aberrations from images. The lens design incorporates one Super ED element and one extra-low dispersion element, which help to reduce color fringing and control chromatic aberrations for improved clarity and color fidelity. In addition to providing more selective focus control, a bright constant f/2.8 maximum aperture keeps performance steady from wide-angle to telephoto focal length settings.
