Fast maximum aperture

A maximum aperture of f/2.8 allows photographers to shoot hand-held in low-light conditions without worrying about blur from camera shake.
 
Aspherical and UD elements

For optimum visual performance the lens incorporates aspherical elements to correct spherical aberrations, and Super UD (ultra-low dispersion) elements to eliminate chromatic aberrations. The result is crisp, high-contrast images that are free from distortion all the way across the frame.
 
Ultrasonic focusing

A ring-type ultrasonic motor drives autofocus extremely quickly, and in near silence. Excellent holding torque ensures the point of focus is reached accurately, without overshooting. Furthermore, full-time manual override is available, making it possible to adjust focus without leaving AF mode.
