The optical formula features 14 elements in 10 groups, including three Super-low Dispersion glass elements for the minimization of chromatic aberrations, and three aspherical elements to reduce distortion and other aberrations. Users of Canon cameras benefit from an ultrasonic-type 'HyperSonic Motor' (HSM) for fast & silent autofocus.The 'DC' designation indicates that this lens is designed for DSLRs with APS-C or smaller sensors, and isn't suitable for use on a full-frame body (the image circle isn't large enough, and vignetting will occur).
