The wide zoom range of the EF 28-200mm f/3.5-5.6 USM makes this a perfect lens for almost any situation. Its sixteen-element design includes two aspherical elements, and it focuses as close as 17.7 inches throughout the entire zoom range, even at the 28mm wide-angle zoom setting. Inner focusing means the front section doesn\'\'t rotate, a real benefit to photographers who use filters. Fast and quiet AF - an EOS hallmark - is provided by Canon\'\'s exclusive micro USM, unique among 28-200mm lenses.
