Although it is a wide-angle zoom, and an ideal supplement to a high-performance mid-range zoom, the 16-35mm range of this lens will satisfy the core focal length requirements of many photographers who shoot primarily indoors or in the city. At the other end of the spectrum it can be a great choice for spacious landscapes as well. Regardless of where or how the SAL1635Z is used, its advanced coated optical path delivers exceedingly crisp images with striking contrast, without the aberration and peripheral light falloff that commonly plague wide-angle zooms. That same superlative quality is maintained throughout the zoom range, even at the maximum F2.8 aperture.
